Ways to insulate frameless hangars

For frameless hangars to maintain ideal temperature control, lower energy costs, and extend the life of the structure, adequate insulation is essential. Effective insulation is essential to creating a cozy and useful space in the hangar, whether it’s being used for equipment storage, housing livestock, or other uses.

Insulation presents special challenges for frameless hangars because of their open-span design and absence of conventional support structures like beams or columns. Frameless hangars, in contrast to traditional buildings, need specific insulation methods to increase energy efficiency and reduce heat loss.

Thankfully, frameless hangars can be effectively insulated in a number of ways, each with unique benefits and considerations. Finding the ideal solution, which ranges from spray foam insulation to reflective insulation, depends on a number of variables, including the hangar’s intended use, climate, and financial constraints.

For insulating frameless hangars, reflective insulation—typically made of aluminum foil or other reflective materials—is a popular option. By reflecting radiant heat, this kind of insulation helps to keep the hangar’s temperature constant. Installing reflective insulation is not too difficult, and it can save a lot of energy in the long run.

Another choice for insulating frameless hangars is spray foam insulation, which has superior air sealing and heat resistance qualities. The entire structure is effectively insulated by spray foam insulation, which expands to fill gaps and cracks and creates a seamless barrier against heat transfer. For many hangar owners, spray foam insulation is a worthwhile investment because of its long-term performance and durability, even though installation may need to be done by professionals.

Insulation Material	Advantages
Fiberglass Insulation	Cost-effective, easy to install, widely available
Spray Foam Insulation	Excellent air sealing, fills gaps effectively, long-lasting
Rigid Foam Insulation	High R-value per inch, moisture resistant, durable

Lifetime

A monolithic hard surface made of submerged polyurethane foam has been in use for decades.

According to the manufacturer’s stated specs, polyurethane foam has a service life of more than thirty years. even make a call for at least 50 years. PPUs may sustain mechanical damage during operation, but this is easily preventable, and repairs seem to be reasonably priced—the costs involved will just be high.

Frameless or frame hangar construction and insulation is a different, complex industry with its own set of nuances.

You should research your options before pursuing it. One of the greatest solutions, in my opinion, for thermal insulation of spaces like hangars and warehouses is polyurethane foam technology, which includes three key elements: swiftly, effectively, and qualitatively. Watch informative videos about this subject:

1 consistency of the polyurethane foam

Any geometric shape can be utilized for hangar thermal insulation by using the polyurethane foam spray method. At the customer’s request, the insulation system is installed either from the inside or the outside of the building.

The following are some benefits of using PPU material:

• Exceptional quality of thermal insulation; high wear resistance; resistance of polyurethane foam to surrounding factors; rapid installation as in the case of liquid he heaters of astratek; absence of seams on the surface of the walls; strengthening the construction of the hangar; fire resistance; low costs for work.

Whether installed from the inside or outside of the hangar, PPU wall insulation is a very efficient way to prevent heat loss. Because of the material’s low heat conductivity coefficient (less than 0.03 W/MK), outstanding thermal insulation is possible.

PPU spraying procedure from the inside on the hangar walls

One significant benefit of polyurethane foam is that it can be used to coat the entire structure, including the hangar’s beams and other components. There are no seams on the processed surface as a result.

This offers a wall type that is aesthetically pleasing and ensures that the structure is adequately insulated.

Whether applied from the inside or outside of the hangar, polyurethane foam keeps its insulating qualities for over thirty years. Furthermore, the PPU spraying method doesn’t require a significant investment and is cost-effective.

Additional fasteners are not needed for the work to be completed, and the design itself does not require the application of a hydro-, steam-, or windproof layer. The time needed to install PPU or liquid thermal insulation from the inside of the hangar is greatly decreased because the hangar doesn’t need to be prepared beforehand.

Types of insulation

Polistyle foam is among the best heaters available today for heat insulation because it has a high level of thermal insulation, doesn’t deteriorate, and doesn’t absorb moisture.

Penoizole is a cheap material that has been known for a century. possesses a small, porous mesh structure. aesthetically pleasing but inexpensive. can be applied as a filling method or in leaf form.

Glass wool, also known as fiberglass, is made up of long, wide fibers with many voids that fill the space in between. This guarantees both effective noise reduction and thermal insulation. It’s said that the material is resilient, elastic, and vibration-tolerant. The fiberglass resists chemical and biological influences and does not burn when it passes steam without absorbing water. used to insulate metal roofs and structures made of wood.

Because mineral wool basalt is made from basalt melts, it has an extremely long service life. is safe for humans because it doesn’t release any harmful substances and doesn’t alter its characteristics in the presence of harsh chemicals or high temperatures.

Materials

Metal structures can have insulation systems fastened to their exterior or interior surfaces. Depending on the type of structure and its intended use, it can be made of polyurethane foam, sandwich panels, or leafy or liquid heaters (ecovata).

Sandwich panels

Sandwich panels don’t freeze and can withstand moisture.

Typical sandwich panels consist of steel profile sheets sandwiched between foamed polystyrene, mineral wool (density starting at 100 kg/cube m), or polyurethane foam (PPU). For internal or external installation, manufacturers provide "sandwiches" for the roof, ceiling, wall, and corners.

A large range of design options are available; the outer sheet can mimic masonry, plaster, or stain wood. An excellent choice for buildings whose appearance is subject to strict specifications.

Slab, roller materials

An efficient thermal insulation system can be created using flexible plates, rolls of natural or synthetic materials (such as glass wool, mineral wool, foamed polyethylene, and non-woven canvases made of plant fibers called holofiber).

Angars’s insulating supplies

Overlapping roller materials are used to solve the cold bridge problem. The only aspects of sheet insulation’s installation that are difficult to use are these:

• crate;
• fasteners – adhesive compounds, self -tapping screws, etc.D.

In addition to adding to the weight on the metal structure, the fastener system compromises the vapor barrier and waterproofing canvases’ tightness. There are more "cold bridges" built. The fabrication of contemporary multilayer thermal insulation systems is made easier by foil materials.

It is challenging to insulate surfaces with intricate patterns, such as protrusions and recesses. Furthermore, the metal hangar’s "soft" insulation is vulnerable to mechanical stresses, so adding a "hard" layer of external decoration is necessary to shield it from harm.

Ecowata, polyurethane foam

In the field of construction, using liquid heat insulators is a relatively new development. They will create a uniform, continuous coating by penetrating even the most difficult-to-reach places.

Ecowata: superior frame structure insulation. The method suggests building a stiff structure and blowing cellulose material into it. Using a moisture and vapor barrier is essential.

Polyurethane foam Angara insulation is the most efficient technique.

There is no need for an extra fastener when using polyurethane or polyurethane foam. PPU is applied to metal surfaces by simply spraying it on, much like staining. There are several layers used. The resultant monolithic surface can be left unfinished, plastered, or painted and is resistant to mechanical damage. Sheet finishing materials (PVC panels, drywall, etc.) are easily mounted on a dense frozen mass. P.

Although the PPU system is resilient to moisture and temperature fluctuations, extra precautions should be taken if direct UV radiation or water damage is anticipated.

It is challenging to isolate insulated arched hangars or other frameless and frameless metal structures, such as tents, polygonal PPUs with straight walls, or ecovite. Technology suggests the use of costly, specialized tools and skilled artisans. Sheet materials such as sandwich panels, rolls, and mats can be fastened independently.

Additionally, there are a number of pre-made options that use liquid, bulk, or leaf building materials to warm the floor surface. They can be fixed straight into the ground. It is possible to install "Warm floor" electric or water systems if needed.

Crucial! No need to schedule a low-cost hangar warming! Insulation should be effective first and foremost. The selection of methods and materials is contingent upon the building’s functionality.

Provisions are made for ventilation, air conditioning, and other communication lines when designing the thermal insulation system. Only by carefully measuring the "pies" of insulation and closely adhering to building codes can high insulation efficiency be achieved.

The reasons for choosing a PPU for the installation of refrigerated cameras

Because of their physical and functional qualities, polyurethane foams are the primary material used for thermal insulation in large volume refrigerated installations and mobile refrigerated chambers.

• A small specific mass of PPU -based insulation allows you to mount refrigerated installations based on ordinary freight transport, such thermal insulation does not create an additional load on the car chassis.
• Excellent adhesion of polyurethane foam allows you to apply it to almost any initial surfaces. In this case, the resulting coating is highly resistant to vibration loads, which arise as a result of the installation that ensures the circulation of the refrigerant.
• Warming with the use of PPU can be carried out both in the factory and at the place of direct installation of the refrigerator. It is thanks to this that the thermal insulation of industrial plants in logistics and shopping centers is carried out by spraying polyurethane foam. Small setting dimensions allow you to perform work both outside and from the inside of the industrial refrigerator.
• Two -component polyurethane foam can be applied in several layers without violation of the monolithic coating. This allows you to obtain thermal insulation of the required thickness (determined by the calculation of thermotechnical characteristics and the required operating mode of the refrigerator). At the same time, spraying is seamless, which significantly reduces the heat loss of the installation.
• The minimum moisture absorption and vapor permeability of the PPU allows you to create the most optimal microclimate in the refrigerator for storing various products. At the same time, the likelihood of condensation is significantly reduced on the installation surfaces.

The cost of producing refrigeration equipment can be decreased by the ability to apply polyurethane foam in a mechanized manner and by requiring a minimum thickness of coating. As a result, the cost of a refrigerated chamber with PPU thermal insulation is comparatively lower than that of other products in its class.

Please take note that the precise cost will only be known after our specialist has visited the location and become familiar with the features of the upcoming work. depends on the area, surface smoothness, humidity, accessibility to the surface, and working conditions (time, temperature, period, etc.), including the tools utilized.

Comparative analysis

A basic comparison of the properties reveals that all materials have nearly the same level of insulation and that foamed polyurethane and polystyrene have the lowest weights. Furthermore, if solid foamy material or mineral wool is used, the weight of the frame structure must be taken into account in the calculation. How using stone cotton wool provides the most dependable fire protection. Nonetheless, installing liquid polyurethane is simpler overall.

The price of the materials is another crucial feature. The most affordable are foam plates, and the most costly are stone-welded heaters. The features of the buildings, the type of wall, and the warehouse’s financial resources all influence the choice of thermal insulation.

Warehouse insulation

The insulation of warehouses is different from that of typical residential buildings because warehouses are larger areas with higher ceilings. Furthermore, not all businesses can afford to temporarily halt operations at the warehouse; as a result, insulation projects should be completed at night or right in the middle of business hours.

Examine a few varieties of insulation for warehouses:

1. Mineral wool. This is a classic way, quite cheap and therefore popular. Mineral cotton wool is fireproof and is not deceived. Its disadvantages are a high ability to absorb moisture and high plates weight, which can be dangerous for walls organized from thin galvanized steel (hangars).
2. Sprayed polyurethane foam. Recently, this is a very popular method of warehousing. Poliuretan foam is not a fuel, has low thermal conductivity and high vapor barrier, it easily and quickly apply it, it forms a dense seamless coating without any “cold bridges”. Its disadvantage is a fairly high cost, and the inability to carry out work with a functioning warehouse.
3. Sandwich panels. Ready -made factory panels are very beautiful, strong enough and do not require additional processing. The disadvantage of the sandwich panels is the complexity of their installation and high weight, which can create an additional load on the walls and the foundation.
4. Polystyrene. A very cheap way, the foam plate is easy to mount even with a working warehouse. The disadvantage is a high -fledged material.

An illustration of using polyurethane foam for warehouse insulation is as follows:

Warming of metal structures by hard PPU

Using polyurethane foam for precisely warming makes it possible to address nearly all issues related to a building’s thermal insulation. Furthermore, technology such as spraying is applicable to almost any structure, despite the geometry metal structures being a rather complex structure. However, from a technological standpoint, polyurethane foam and metal structures are very similar:

Comfortable. Metal structure: Out of all the options that have been available up to this point, this is the building’s easiest supporting frame. One of the lightest materials for thermal insulation with the highest coefficient of heat-saving properties is poliuretan foam.

Dependability. Because they are constructed with state-of-the-art technology, metal structures are very reliable. Modern equipment and forward-thinking manufacturing techniques determine the optimal operational properties of polyurethane foam, which is used for spraying.

Transparency.Because of its high density, liquids and gases cannot pass through the metal. Since many structural elements are joined by welding, the joints also have the aforementioned qualities. Excellent thermal insulation qualities are not the only benefits of poliuretan foam. Metal constructions Absolute tightness and moisture resistance characterize polyurethane foam construction insulation because there are no joints in this thermal insulation material. Foam insulation also shields the metal from the damaging effects of corrosion.

Cost savings and improved output. As was previously mentioned, using metal structures typically lowers construction costs and speeds up work. In addition, support foam spraying It can be completed quickly and in very large quantities, and the cost of the building’s thermal insulation is kept to a minimum because no extra fasteners or auxiliary frames are required.

Advantages of PPU insulation on metal structures

Since polyurethane foam is extremely resistant to atmospheric phenomena, processing metal structures both inside and outside the structure is unquestionably another benefit of liquid foam. Simultaneously, the geometry of metal structures is meaningless, regardless of whether they have straight walls, domes, or arches, and sealing complex architectural forms in buildings is a common issue when using different types of known heaters. Consequently, spraying technology insulation Both residential and high-rise buildings are appropriate for Angarov.

Also, the technological features of metal structures often make it impossible to use Tolstoy Thermal insulation layer, And this despite the fact that the metal itself has a very high degree of thermal conductivity. That is, in this case, a rather difficult problem arises – to ensure the heat conservation of the building by neutralizing thermal conductivity metal, but without violating the technological requirements for the thickness of the thermal insulation layer. Exactly Warming of metal structures polyurethane foam allows you to easily solve such problems, since liquid foam has the lowest coefficient of thermal conductivity, therefore, even a small A layer of spraying will create a reliable and effective thermal shell of the structure.

Buildings with metal structures that isolate sound are also prone to this issue, which affects both residential and commercial structures. And in this instance, using polyurethane foam for warming allows for the creation of the coziest indoor environment possible because it offers acoustic insulation, one of its distinguishing qualities.

Considering everything mentioned above, we can state with confidence that the production of metal building frames and the application of polyurethane foam insulation represent the most effective combination available today. The only things you can add to this are a longer working life for metal construction structures made of polyurethane foam, absence of condensation and decay, absence of an aggressive atmosphere, and chemical and biological inertia. In other words, it eliminates every drawback that regular metal has.

It is important to know that when warming, only a classic PPU is used with a density of 45-60kg/m3 on a freon basis.

Alternative insulation options

Insulation of frame-tents of the hangars is carried out, as a rule, even in the conditions of the factory. If there is a need to purchase a heat -insulated design, then your desire should be declared to the product supplier. He will make sure that the tent coating is three -layer: thermal insulation will be located between the layers. This allows you to operate such structures at a wide temperature range: from -55 to +70 °. Depending on the region, frost -resistant materials can be used, which increase the quality of thermal insulation. There is another way of insulation, during which the tepofol is used. It is used for frame structures, and for the work should be prepared wooden bars, construction glue or stapler, additional insulation of the electrical wiring and nails.

Thermo -insulating materials of the bygone century

This is not to argue that they are not utilized anywhere nowadays. Even now, contractors who want to save as much money as possible for themselves use these materials to build homes and apartments, warm certain commercial and industrial facilities, and build private structures.

Styrofoam

Everybody is familiar with this material. In certain nations, it is still utilized as an external insulation today. But there are a lot of risks and challenges involved in using it. Among the drawbacks are the following:

Some nations still utilize foam as an external insulator today. But there are a lot of risks and challenges involved in using it.

• High degree of combustibility – foam is blazing like high -octane fuel. At the same time, he releases toxic volatile compounds into the air – pure poison. Extremely dangerous for people"s life and health
• Loves only even planes – it is pretty fragile. This is a sheet material that can only be used on flat walls. The lack of flexibility makes it impossible or extremely difficult to warm the structures of irregular shapes
• Installation is destructive for the base – requires the use of anchors. You can fix it not everywhere. Violating the integrity of the base, experts lower the operational period of the entire structure
• Short-lived-average service life of only 15-20 years

Even though they would like to save money, they are unable to do so and cannot be isolated from a distance. Additionally, joints greatly lessen its effectiveness. Furthermore, discussing environmental cleanliness is also unnecessary. thorough protective finishes are necessary. Thus, please remove it right away from our applicant list.

Master’s advice: 90% of the time, foam—like a waterproofing coating, which is typically made of regular polyethylene—gets damaged when backfilled with soil. Consequently, the wall becomes windier and loses heat efficiency as a result of rising groundwater levels.

Mineral wool

More safe material than polystyrene, at least because it doesn’t support burning. It’s not entirely safe, though, because he releases volatile formaldehydes when exposed to fire or even very high temperatures. Since the material necessitates the use of additional fasteners, installation is also associated with several challenges. However, this is not the primary flaw in the content:

Mineral wool is a safer material than polystyrene because it doesn’t support combustion, at least not in general.

• Afraid of moisture – when getting wet, it loses up to 80% of its nominal efficiency
• It is a heavy and dense leaf material – this indicates not only about the impossibility of applying the vaulted roofs of the hangars for insulation, but also about the presence of seams that are a weak point of any insulation
• The durability is average – the service life does not exceed 25 years

This material isn’t even close to being the best insulation. However, a lot of businesses sell these materials for insulating hangars, warehouses, and vegetable storage. Furthermore, we highly advise against using these "bear" services. Ultimately, a more contemporary substance exists that is far more potent. Why not use mineral wool to stay warm? The video contains the solution:

How we are working

It is well known that in recent decades, the vast majority of arched hangars under construction in our country are quick -made structures. Moreover, hangars can be used as a trading or trading and warehouse, market, production workshop, parking lots. Such a structure costs inexpensively at the purchase and installation stage, and installation is done very quickly. Long is the life of the structure, which is ensured by high operational properties of galvanized steel, corrugated board. But in the climatic conditions of Russia, the full -functional operation of such structures is almost impossible without thermal insulation. And it is the insulation of the hangars and warehouses of the PPU that is the best option for resolving the issue! The best method is primarily because the thermal insulation layer is very light, it practically does not create an additional load on the structure. High adhesive characteristics of polyurethane foam allow it to quickly and successfully spray it to various kinds of structural elements, walls, ceiling, provide an uniform insulation layer without the use of fasteners, the occurrence of "cold bridges". PPU has low water and vapor permeability, and the absence between the thermal insulation layer and the construction surface of the clearance excludes the appearance of condensate.

How can I order insulation for a hangar or warehouse from "Technopen" with PPU spraying? What will be the process for carrying out the calculations and work?

Our work is built so that customers have to spend a minimum of time and effort. By phone, through the site you can provide all the necessary information about the object, apply for an application. In the agreed time, our employee comes to the object and examines it. If the thermal insulation service of the Angara or warehouse is provided in Moscow, then the examination is not paid. According to the terms of the concluded agreement, the customer makes 50-70% of the prepayment (necessary for the purchase of compositions, payment of transport). Within one to four days, the necessary equipment is delivered to the facility and the warehouse or hangar is insulated with the spraying of PPUs. When accepting work, quality control is carried out using thermal imagers (this service is provided for free). A 5-year guarantee is provided for thermal insulation work.

Insulation

Angars from metal structures are not supplied with heating systems, since in implementation they are quite complex and costly. In order to exclude damage to building materials, as well as failure of the equipment stored in the warehouse, thermal insulation should be carried out. This allows you to maintain a certain temperature inside the building for a large amount of time. The described solution is profitable from an economic point of view, as it avoids the cost of heating. It does not delay heat inside the building without thermal insulation, since the walls have a slight thickness (maximum 2 mm). The formation of condensate due to temperature changes can cause metal corrosion. In this case, there is a need to spend money on protecting the material or pay money for electricity.

1 Process of Angara insulation using a video video

Arched hangars are a very profitable and popular way to save construction costs these days. These buildings serve a variety of equally vital purposes, such as parking, storage, and transportation (garages).

These designs serve as the foundation for offices, workshops, and retail spaces.Apart from the undeniable benefits, diabetes is noted when the hangars are in operation.The primary disadvantage of arched constructions is the intricacy of heating steel due to its 1-1 thickness.The 2 mm used for collecting arched structures is not very heat-resistant. Large arched hangars that are expertly heated are an extremely costly pleasure. For this reason, the hangars need expertly installed, high-grade thermal insulation.

Floor insulation

It is also possible to insulate an earthen floor. The top 15 cm of soil must be removed in order to accomplish this. Next, apply a layer of either expanded clay or sand. This will enable you to level the surface and is also required for drainage to prevent moisture buildup beneath the insulation.

Stoves made of foam are then laid. 5 cm is a sufficient thickness. Additional waterproofing is not necessary for this material. Sand with a thickness of three to four centimeters is poured on top of the insulation. A reinforcement frame needs to be installed on top of the structure in two layers, each measuring one centimeter. It’s essential for screed. After adding cement mortar, wait.

Screed can be substituted with a dodgy board. In order to accomplish this, drainage is installed with wooden lags spaced 30 to 40 cm apart, separated by foam or polystyrene. Foam needs to be poured into all of the cracks. Attach the boards to the top of the lags. You can apply linoleum as a finish. It is preferable to begin any garage insulation with the floor.

If not, it will be difficult and inconvenient to complete the work without causing any damage to the wall decorations.

2 Technology of insulation by means of PPU

The first steps in the PPU insulation process are the initial drying of the treated surfaces, dust removal from the walls, and degreasing. These unfavorable circumstances make the composition stick together less well and impede the flow of chemical reactions.

If rusting, metal structural components are cleaned. Testing is a necessary step before insulation; a control sample of the composition is applied to the surface and the process of hardening the masses can be tracked.

Once the outcome aligns perfectly with your expectations, you can move on to the main task. PPU spraying is done in multiple layers, with the first layer having a thickness of 10–15 mm, in conjunction with the installation of vapor barrier isoospan. Applying the second and third comes after a few minutes.

When the ambient temperature rises above 10 °C, insulation must be done to prevent disruptions to the chemical reaction process. Rain and higher air humidity have negative effects.

By following a few basic guidelines and keeping an eye on the technology, you can effectively insulate the structure, shield it from the elements, corrosion, and rodent infiltration, and lower hangar maintenance costs by using less heating.

2.1 The process of warming the hangar using PPU (video)

Insulation of mineral wool

Wool made of stone or slag is used to warm the hangars. Because they come from nature, they are safe to use. Dangerous impurities do not release even when heated.

These kinds of insulation simply function. Long, entwined fibers serve as a representation of the structure. They do not irritate the skin and are not in flight.

Work with materials without wearing a protective suit or taking any other safety measures.

The material’s thermal conductivity is:

• 0.077- 0.12 W/(m*K) for stone cotton wool;
• 0.46- 0.48 W/(m*K) for slag.

It is evident that there is little heat retention. As a result, foil-layered matting are frequently utilized. Benefits of applying the reflective surface:

• retention up to 98% heat in the room;
• reflection of cold from the outside;
• reduction of thickness, and, accordingly, cost, a layer of insulation;
• Reducing the expenses of the Angara heating.

It is mounted inside the room on one foil side. The insulation is installed from the outside of the structure. Constructively, the air gap forms in front of the reflective coating. If not, you must make arrangements. Minimum layer thickness of 1 centimeter.

Two methods are available for warming a metal hangar:

Varieties of warehouses, hangars and vegetable stores. Their design features and the requirements for insulation from them

It will appropriately take into account the most typical hangar, warehouse, and vegetable store types first. You’ll be able to comprehend which insulation materials are essential better as a result.

Angars

Various kinds of equipment and equipment are frequently stored in these kinds of objects. It can include aircraft equipment, farm vehicles, and much more. The following are some of the hangars’ features:

Angars are frequently used to store a variety of equipment and tools. It can include aircraft equipment, farm vehicles, and much more.

• They differ in large scale – the height, width and length of the hangar should allow large equipment to accommodate
• Using vaulted roofs – for hangars, this is the optimal design. In fact, this avoids the need to erect walls, but during the construction of large hangars for certain types of equipment, walls can also rise, to which a vaulted roof is mounted
• The use of thin sheet materials – thin -leaf steel is often used for construction, which is sheathed with a metal frame. This allows you to reduce expenses in the construction of such large objects

Wood can be used to line old hangars. However, it is extremely uncommon these days. The specifications that the insulation must fulfill are determined by the design elements of these kinds of objects themselves:

• It should be easily fixed on metal thin surfaces
• Should tolerate the dynamic thermal deformations of the base, since the metal reacts very sensitively to changes in temperature
• It should be highly effective – in fact it will not only insulate, but to make 95% of the thickness of the entire wall, so it should be as effective as possible
• Possess a small mass – the vaulted roofs of such hangars are designed for certain loads, so they cannot be overloaded. And taking into account the scale of the structure, the use of heavy heater is simply unacceptable

Warehouses

This idea is very flexible because the warehouse can be built using nearly any type of building material, can have any design, and can be just a small portion of a larger real estate complex. Warehouses can simultaneously hold nearly any kind of equipment, raw material, or good. As a result, the insulation will be subjected to requirements. You can mention the following in addition to what has already been said regarding the hangars:

Almost any type of equipment, raw material, or good can be kept in a warehouse. As a result, insulation is subject to laxer regulations.

• Resistance to moisture and chemicals – the warehouse area can periodically undergo sanitary treatment using water and chemicals, so the material should not be vulnerable to them
• The possibility of applying almost any surface – a warehouse can be built of metal, stone, concrete, wood or their combinations. The material should be perfectly held on any basis
• To differ in maximum efficiency with a minimum consumption of the useful volume of rooms – if the insulation layer is too large, and an additional frame will be needed to fasten it, then its use will be inappropriate, as this will go to the minus of the useful internal volume of the warehouse
• To be affordable – there can be a lot of insulation – it all depends on the scale of the warehouse. Therefore, the price of the material should be not only acceptable, but also fully justified, economically justified

Vegetable stores

These are hangars or specialized warehouses made just for keeping fresh fruit and vegetables. In this case, the humidity level and temperature range are very crucial. They are frequently built of stone or concrete and come with required refrigeration and ventilation systems.

In this instance, it is crucial to ensure the vegetable store is adequately insulated to minimize energy consumption and maintain its functionality. Given that we’re discussing food storage, environmental purity and chemical neutrality are two essential criteria for insulation.

Toxic substances should not be released by thermo-insulating material under any temperature conditions or influences. Its operating temperature range should also be sufficiently broad.

Why is it worth warming the hangar with polyurethane foam

You must comprehend the various types of thermal insulation found in these kinds of rooms in order to respond to this question. The hangar can be warmed using two primary methods:

• tile building materials;
• The gradual spraying of polyurethane foam.

Polyurethane foam insulation system by Angara.

Mineral wool, basalt fiber, and polystyrene foam are typically utilized in the first method. The thermal conductivity of the processed floor can be greatly decreased by warming with these materials, but the floor will become more vulnerable to moisture buildup from condensation. The setup of the crate—into which the plate of the chosen building material will be inserted—is part of the thermal insulation technique with tile heaters.

Before putting the metal mesh crate in place, the material that shields the structure from the elements must be mounted, and vapor barrier polyethylene must be stretched over it. It is obvious that this approach will cost a significant sum of money, especially considering how difficult the thermal insulation procedure is. Additionally, because lightweight metal structures are more likely to experience slight deformations due to mobility under wind pressure, there is a chance that the film used for steam isolation will wear down quickly in the winter.

The technology used for thermal insulation with tile building materials is significantly different from that of polyurethane foam. It is important to remember that polyurethane foam (PPU) has a high adhesion level. This eliminates the need to build a crate and lets you process the surface. Angars insulation is applied seamlessly, without creating cold bridges.

Diagram of the insulated hangar’s transverse section.

An additional layer of protection against condensate and wind pressure is not necessary for this material. It can be sprayed from outside or inside. It is sufficient to apply a specific mixture to the thermal insulation layer in order to shield it from sunlight’s UV rays when using the second insulation method.

Mineral wool puts a lot of strain on the metal structure; in contrast, polyurethane foam for hangars reinforces the walls’ structure without adding extra bulk. For frameless hangars, this is especially helpful for thermal insulation.

Polyurethane foam also has an aesthetic benefit. You can leave the hangar in this state once the thermal insulation is finished. Of course, you can paint the desired color over this layer if you’d like.

Go back to the contents table.

Ways to insulate structures made of metal and concrete

Among the many techniques for keeping the warehouse warm, a few stand out as being particularly effective.

Method 1: Creating an internal circuit

The process of creating a light, insulated, non-carcass structure inside the hangar is the insulation by internal circuit building method.

Several technologies can be used for installation, such as metal profile frames or wooden racks, in which panels are installed after polystyrene or slab insulation has been installed.

The method’s reduction of the warehouse’s useful area and the high cost of the design are significant drawbacks.

Method 2: insulation slabs of basalt and glass wool

Slab, basalt, or glass wool insulation is an effective way to retain heat, but it is inconvenient to use. This option is actually the same as the inner contour, but the frame is fixed straight into the warehouse walls.

Additionally, this loads the Angara sections, which may compromise stability. Additionally, installing rails or profiles for wall steel might present some challenges. Moisture that does not evaporate and inevitably builds up in the insulation thickness is another drawback of this technique.

Method 3: Foam as a heater

Polyurethane foam warming gained popularity. There are two different forms of this material: plates and a liquid mixture that foams separately after application. Slabs are used to insulate the exterior of concrete or wooden walls, and foam is applied to the walls within. For steel structures, liquid polyurethane is most likely the best insulation option.

Any surface can be effectively adhered to by construction foam. Its thermal systems are independent of the wall’s shape, and the layer’s thickness allows for adjustment of the insulation level. The inability to process at negative air temperatures and walls can be regarded as a drawback.

Materials for insulation

Foam and mineral cotton make an economical and efficient hangar insulation.

Angar can have both interior and exterior insulation. The purpose and design of the building determine the material selection. Most frequently employed:

• sandwich panels;
• sheet heaters;
• Liquid thermal insulation materials.

Garage insulation and Angara insulation are extremely similar. See our article on garage insulation for additional information.

Sandwich panels

The material is available in multiple configurations:

• with polystyrene foam;
• with dense mineral wool;
• with PPU (polyurethane foam).

In any event, the insulation is situated between metal sheets that make up the panel. Installation of the panels can be done inside or outside. Manufacturers provide "specialized" materials, such as corner-configured "sandwiches" and floor and ceiling slabs.

The panels’ unique feature is their extensive assortment of external embellishments. The exterior can be painted, processed "under the tree," or made to resemble brickwork or embossed plaster.

If the hangar’s appearance is important, it’s worth investigating the different sandwich panel options in more detail.

Warms in rolls and plates

Rolls and slabs with heaters are useful for work, and they can be made of both natural and artificial materials. Even in metal structures, a stable microclimate can be created with foamed polyethylene, non-woven canvases, and mineral and glass wool.

Rolling materials: an incredibly practical method for working in big spaces

Overlapping rolled materials prevent the formation of "cold bridges." Another technology is used when putting in the insulation in the plates: glue, dowels, and screws are used to secure the material to the crate.

Fasteners increase the load on the building’s walls. Furthermore, unneeded "cold bridges" appear, disrupting the layers of waterproofing and steam protection as well as the tightness of the slabs themselves.

The intricacy of processing angles, joints, and uneven surfaces is the drawback of the insulation of metal structures with slabs and roller heaters. Furthermore, heaters are vulnerable to mechanical damage, so an external sheathing that is reasonably strong and hard to mount must be placed on top of them.

Ecowata, spraying from polyurethane foam

Not too long ago, liquid insulation materials were introduced to the market. They provide a consistent layer of coating and dependable thermal insulation because they can fill in even tiny cracks and "hard-to-reach" areas.

Ecowata works great with framework constructions. Insulation is positioned between pre-built intervals of a sturdy base. A hydro- and vapor barrier is required with this type of insulation pattern.

The nuclear cotton wool swings nearly in a monolithic fashion against the wall.

Installing extra structures is not necessary when using polyurethane foam for thermal insulation of the building. PPU is sprayed all over the walls in an even layer, just like paint. You will need to apply the composition multiple times to achieve optimal protection against the cold. Finishing (plaster, paint, drywall) or leaving the walls bare is also an option. The polyurethane foam insulation protects the surface from mechanical forces.

PPU coating can withstand variations in temperature and elevated humidity with ease. It is preferable to further protect the surface from direct sunlight and water.

Advantages of insulation of the vegetable store with polyurethane foam

PPU stands for polypropylene. It can be used to create the required microclimate in vegetable stores, waterproof basements, and warm the hangar from the inside out.

Certain airplane and air temperature parameters were observed in order to maintain the proper microclimate inside the warehouse where vegetables are stored, enabling them to be preserved until a new harvest. This can be accomplished by using foamed polyurethane for thermal insulation, which not only acts as a waterproof barrier but also stops moisture from evaporating from the storage and from penetrating from the outside.

Low humidity levels are crucial for the effective storage of grain crops, and the waterproofing qualities of polyurethane make it the best choice. If not, the grain may bloom and eventually disappear entirely or lose some of its class value.

Additionally, because polyurethane foam has protective qualities, using it to insulate wooden granaries from heat helps stop treewoods and other harmful insects from spreading throughout the wood.

Outdated and most dangerous insulation

In an attempt to determine what is acceptable and clearly inappropriate for hangar and warehouse insulation, we will perform a sort of hit parade. Now let’s begin with the least expensive option, foam.

Everyone knows the formula: low cost, quick turnaround, and high efficiency. The drawback is that you are limited to selecting two elements. There is just one component in the case of the foam, and that is cheap. What dangers are therefore in store for anyone wishing to utilize this material?

• It is extremely dangerous – Foam burns like gunpowder! But even worse, he distinguishes by the by -products of combustion – poisonous toxins that can kill all living things. Therefore, it cannot be categorically used for internal insulation
• Installation takes a lot of time and effort- the use of fasteners, decoration of the seams, additional protection of foam – all this seriously complicates the work. Foam – fragile material. It is not suitable for insulation of structures of complex forms, and is also very afraid of mechanical influences
• Fragility- As a rule, such insulation requires improvements after 5 years, and a complete replacement after 10 years

Simply put, move on. Only external insulation should be used with foam, and even then, there is a big "but."

Glass wool or mineral (basalt) cotton wool are further options. The substance is more secure. At least he does not burn, nor does he encourage burning, even though the half-life temperature frequently stays below 100 degrees Celsius. The issue is that these materials are only appropriate for frame structure insulation, necessitating the installation of additional waterproofing.

All of this is therefore condensed into a monetary sum that not everyone will be willing to spend. And even with the greatest of desires, the installation cannot be deemed operational.

Features of applying polyurethane foam

This kind of thermal insulation is a member of the gas-filled plastics family, also known as polystyrene. Polystyrene and urea-type plastic products are comparable to polyuertan foam.

Two types of liquid are delivered to the hangar location:

The wiring schematic for the installation’s parts that spray polyurethane foam under pressure.

By using the air spraying technology, the air pressure causes the two liquids to mix inside the nozzle. This technique allows the smallest particles to form an even layer that reaches the most difficult-to-reach places on the metal structure, much like an aerosol. An impenetrable layer is created by meticulously plugging all crevices, holes, and cracks.

A chemical reaction takes place during the application of the polyurethane foam to the hangar, causing the sprayer to foam and start to harden. A layer of the applied mixture hardens by 90% after two hours, and by the end of the day, this percentage has increased to 100%.

Since 80–90% of the mixture is made up of air, there are a lot of pores in the form that polyurethane foam is applied to. The air is responsible for the polymer properties of the material acquiring strong thermal insulation properties.

Any hangar will contain acid, alkaline, fuel, and oil exposure, all of which polyuertan foam is well-suited to withstand. It is therefore perfect for premises of this orientation. PPU can be applied to the following surfaces because of its high level of adhesion:

• metal;
• reinforced concrete;
• arched openings;
• ceiling coating;
• Coating with recesses and protrusions.

The high evaporation and moisture resistance of polyurethane foam eliminates the need for additional steam and waterproofing material surface protection.

Furthermore, since animals do not come into contact with PPU surfaces treated with this kind of material, there is no need to protect it from mice and rats. Furthermore, it doesn’t develop any fungus or mold on it. The only thing that can destroy polyurethane foam is mechanical damage; exposure to air or temperature does not work against it.

Go back to the contents table.

Why should you warm the hangar

Such a hangar’s functionality and range of applications are enhanced by high-quality thermal insulation. Therefore, a warm building can serve as an administrative space, a production workshop, a sports complex, or a farm.

Contemporary insulation materials, including foil foamed polyethylene, mineral wool, PPU, and others, are safe, environmentally friendly, and fire resistant, and they can be utilized in residential buildings as well.

Thermal insulation also addresses the following set of issues:

1. Low noise insulation. Metal structures are practically not isolated from noise. The use of insulation, in addition to reducing heat loss, will also provide insulation from noise.
2. Hypothermia and heating of the room. In winter, thermal insulation retains warm air inside, and in the summer-on the contrary, prevents overheating of the building due to high temperature on the street.
3. Insufficient strength of the hangar. The use of several layers of the heat -insulating material gives the walls additional strength and rigidity, and also protects from condensate and the occurrence of rust.

Why insulate the hangar

Angara insulation is a prerequisite for achieving cost savings in the business world.

The hangar’s thermal insulation will increase the space’s usability. The insulated building can serve as a living room, an office, a sports or retail complex, or even both. Modern materials allow you to maintain a building’s fire safety, meet code requirements, and create a comfortable microclimate without endangering occupant health. Angara insulation is expensive, but as a "side effect," it will solve a number of additional issues.

Noise insulation

Metal buildings have poor sound insulation. When using the hangar for residential or commercial uses, noise absorption and insulation are equally important, including:

• trade area;
• workshop;
• administrative or sports facility;
• dormitory;
• vegetable store;
• structures for the maintenance of animals and birds.

The hangar is not only less "noisy" in the city or during rain after insulation. Additionally, "regular" background noise from the street is kept out of the interior space.

Heating protection

In a building, thermal insulation maintains a comfortable temperature. It keeps the room from losing heat in the winter and from overheating in the summer.

This kind of thermal insulation is particularly crucial when a building is being used for residential, commercial, or storage purposes.

Increasing strength

Multiple layers of thermal insulation give the building’s walls more rigidity. Following the installation of the insulation, the metal structure will also be shielded from condensate, which is another enemy of the primary material and whose appearance over time may cause rust to form on the walls.

Angara insulation may be just as expensive, but it also increases the structure’s dependability and the room’s potential functionality multiple times.

Materials for floor insulation

Wall and floor insulation need the same supplies.

You also need to heat the hangar’s floors in addition to insulating the walls. Leaf materials, bulk mixes, or liquid compounds are utilized for this. Installation is typically done straight down the ground; extra simple structures are hardly ever used. It is technically feasible to set up "warm floors" in the hangar (both electric and water systems).

The selection of a heater for metal structures begins with the hangar’s purpose and design.

Even with cost-effective materials, such an event won’t be cheap, so the efficiency of thermal insulation is given more consideration.

It’s critical to find effective ways to insulate frameless hangars when it comes to home insulation and heating. Because of their unusual design, these hangars—which are frequently used as workshops or for storage—frequently lack conventional insulation techniques. Nonetheless, a number of practical tactics can be used to maintain these areas’ comfort and energy efficiency. There are solutions to fit different needs and budgets, from installing radiant barriers to using reflective insulation materials. Further improving the thermal performance of frameless hangars can involve adding insulation to the walls and ceiling and sealing air leaks. Homeowners can enjoy a more comfortable environment, lower energy costs, and less of an environmental impact by putting these strategies into practice.

Polistyle foam for insulation

Foam polystyrene insulation is a premium form of seamless thermal insulation.

Polystyrene foam can be used for Angara insulation. Polistyle foam is a synthetic material with good thermal insulation and moisture resistance.

It does not become wet, deform, or change its chemical or physical properties when exposed to moisture. Additionally, it resists both biological and chemical agents well. Its low cost also contributes to its high demand.

Notwithstanding their benefits, it’s crucial to remember that they should only be used to warm the floor in order to prevent heat loss from below. It’s not quite right for walls.

Polystyrene foam is used to create other materials and can also be used to warm the hangars.

They consist of foam, foam, and extruded insulation first. A foaming substance is used to create foam, which has a low mass and is filled with air—both of which effectively remove heat. Gas foam results in the formation of extruded insulation.

His cellular structure is akin to that of a sponge. its strength is high, unlike foam. The foam’s limited use stems from its inability to absorb moisture.

Properties and comparison materials

Take into consideration a few fundamental qualities that are important in particular for warehouse and hangar insulation:

• thermal conductivity, t. e. the degree of insulation of the layer of a certain thickness;
• combustibility or ability to maintain combustion. The protection of the premises from the fire depends on this parameter;
• The specific gravity or the load that the construction structure from insulation will suffer.

Mineral wool

The indicators on this insulator are as follows:

• Specific thermal conductivity: about 0.030 W/m*K*. This figure is characterized by both glass wool and basalt materials;
• Facuity: do not burn and do not support combustion. Glass wool slabs withstand the temperature up to 400 ° C without loss of properties, and the plates from the basalt fiber – up to 1000 ° C. The walls of the warehouse covered with basalt fiber are able to withstand open fire for a long time;
• Specific weight: depends on the density of the plate and ranges from 35 kg/m3 to 180 kg/m3. For insulation of a steel wall, 15 cm layer is enough with a density of 100 kg/m3. Thus, on a plot of 1 m2, the load will be 15 kg.

Foam and polystyrene foam

In a solid, slab design, foam, or polystyrene foam, has the following characteristics:

• thermal conductivity: for foam – 0.037 kg/m3, for polystyrene foam – 0.027 kg/m3, which is quite comparable to the characteristics of mineral watts;
• The degree of combustibility: polystyrene foam and polystyrene foam can burn, however, antipypees are added to them in modern production, which allows these materials to assign the combustibility class G1 and call the combustion of combustion. The heat resistance of foams is low-they do not withstand heating even up to 250-270 ° C, and when burned, the gases are distinguished for humans;
• Specific weight: foam-100 kg/m3, polystyrene foam-40 kg/m3, polyurethane foam (installation foam)-40-80 kg/m3. 1 m2 of polystyrene with a layer of 15 cm will have a weight of 15 kg, polystyrene foam – only 6 kg, and polyurethane foam – from 6 to 12 kg.

The properties of construction or installation foam insulation are identical to those of polyurethane foam slab materials.

Angara insulation with foam

Tepofol, also known as thermal insulation of foam, is a material composed of polished foil or metallized film and foamed polyethylene foam. Tepofol is a material that combines soundproofing, waterproofing, and thermal insulation. Because of the polished foil, which can reflect up to 97% of thermal energy rays, it has extremely high reflective qualities. Additionally, his porous closed structure eliminates all chance of moisture and steam absorption or stagnation. Polyethylene’s high reflectivity and low thermal conductivity prevent heat loss by over 30% and effectively shield treated wall surfaces from moisture and purging.

Penophol’s benefits:

• exceptional characteristics of elasticity;
• stability of the original shape;
• The material is absolutely safe for human health;
• good hydrophobic;
• excellent vapor permeability indicators;
• durability and wear resistance (with competent installation, the material will last more than a dozen years);
• resistance to corrosion and mechanical damage;
• resistance to atmospheric precipitation;
• high degree of noise and thermal insulation;
• Biological stability – the material is “not interested” of rodents and insects, mold or fungus does not appear on it;
• ease and ease of transportation and installation;
• lack of need for additional care;
• The possibility of combining with different building materials (gypsum, cement, lime, concrete).

Even after many years of use, Tepofol’s thermal insulation maintains all of its original qualities.

Two varieties of penophol (TePofol) are produced:

• Foamed foam – performs reflective thermal insulation and has a good absorption of noise.
• Penophol metallized – has a high degree of resistance to organic solvents and the effects of acids, and also has good mechanical strength.

When the reflecting layer is present on both sides of the coating, both types of material can be produced in the one-sided and bilateral options. Penophol can also be purchased as NPE tepofol, which lacks the upper additional layers entirely, and self-adhesive, which is available when there is an adhesive coating on one hand that makes installation easier.

Any structure’s primary insulation (ranging from 40 to 150 mm) and supplementary insulation (ranging from 2 to 10 mm) are made of tepofol.

Warming glassy

And lastly, glass wool insulation in its third iteration.

Glass wool (glass wool) is a fibrous insulating material consisting of recycled glass, soda, sand, and limestone.

Because the static air is trapped between the fibers of glass wool, the air in a room that is isolated by such a material stays warm. Glass wool is renowned for having outstanding sound-absorbing qualities as well.

The principles of glass water insulation and mineral wool insulation are very similar in that they both require a heater to be positioned between two layers of arched constructions.

Glass wool video footage:

• low thermal conductivity;
• high sound absorption;
• souvenism;
• does not deform;
• Saves thermal insulation properties.

A critical component of preserving ideal temperature control and energy efficiency is insulating frameless hangars. Homeowners can minimize heat gain in the warmer months and drastically reduce heat loss in the colder ones by properly insulating these structures. This article has examined different materials and techniques for insulating frameless hangars and has offered insights into how each can improve thermal performance.

Selecting the appropriate insulation material is a crucial factor to take into account when insulating frameless hangars. There are differences amongst options like fiberglass, spray foam, and reflective insulation in terms of cost, ease of installation, and efficacy. Homeowners should assess their unique requirements and financial limitations in order to choose the best option for their project. In order to guarantee optimal insulation performance and longevity, proper installation techniques are also crucial.

Moreover, minimizing air leakage is essential to reaching the highest level of insulation efficiency. It is possible to stop hot air infiltration in the summer and cold drafts in the winter by caulking gaps and cracks surrounding doors, windows, and other openings. Using foam sealants, caulking, or weatherstripping can help form a tight seal and increase the insulation system’s overall efficacy.

It is crucial to take into account the overall design and layout of the frameless hangar in addition to the insulating materials and air sealing techniques. Enhancing energy efficiency and indoor comfort can be achieved by implementing strategies like orienting the structure to maximize solar exposure or incorporating passive ventilation. Through a comprehensive approach to insulation and design, homeowners can establish a more comfortable and sustainable living space.

In summary, homeowners can increase overall comfort, lower utility costs, and improve energy efficiency by insulating frameless hangars. People can effectively mitigate heat transfer and create a more resilient and sustainable living space by choosing the appropriate insulation materials, taking air leakage into consideration, and taking design elements into account. Long-term energy savings and environmental benefits can result from investing in high-quality insulation and installation now.
