Insulation is essential for maintaining a comfortable and energy-efficient home. Polyurethane foam is one of the well-liked solutions that is garnering interest. It is not only reasonably simple to apply, but it also works well to seal cracks and gaps. You can take on this do-it-yourself project to increase the comfort and energy efficiency of your home if you have the necessary tools and a little know-how.
There are two varieties of polyurethane foam insulation: closed-cell and open-cell. Closed-cell foam is denser and offers superior insulation, whereas open-cell foam is softer and more flexible. Due to their superior thermal resistance, both varieties aid in keeping your house cool in the summer and warm in the winter. Polyurethane foam can drastically lower your energy costs by acting as a barrier against air leaks.
The capacity of polyurethane foam insulation to expand and fill even the smallest gaps and cracks is one of its greatest benefits. Because of this characteristic, it works especially well for sealing spaces that conventional insulation materials might not be able to. Polyurethane foam can be used to create a seamless barrier that stops heat loss and drafts around windows, doors, crawl spaces, and foundation walls.
The longevity of polyurethane foam insulation is an additional advantage. It creates a solid bond with the surface when applied correctly, offering long-lasting protection. In contrast to certain alternative insulation materials, polyurethane foam exhibits resistance against moisture, mold, and pests, guaranteeing the comfort and well-being of your home for an extended period.
Although you can always hire a professional installer, doing the polyurethane foam insulation application yourself can save costs and provide a sense of pride. Many homeowners are able to complete the project in a weekend if they take the proper safety precautions and apply the proper technique. We’ll walk you through the process of adding polyurethane foam insulation to different parts of your house in the upcoming sections, so you can improve both comfort and energy efficiency.

Properties and characteristics
Polyol and Polysocyanate are the two polymers used to make polyurethane foam. Components are combined, heated, and carbon dioxide is added before application to the surface. High pressure insulation spraying enables efficient insulation of even challenging-to-reach areas beneath the roof or in between communications. The substance becomes a tough, long-lasting coating with a knobby surface and no seams after curing.
The polyurethane foam’s appearance
This insulator has a lot of advantageous qualities.
- low thermal conductivity ;
- complete tightness;
- environmental friendliness;
- immunity to chemical agents;
- low weight;
- durability.
The material is also very firmly attached to any surface, has outstanding sound insulation, and prevents moisture from passing through. Even on the smoothest coatings, the insulation is consistently retained because of its high adhesion. Polyurethane foam can withstand severe temperature changes without catching fire, and it is not afraid of mold, insects, or rodents.
The cost of the insulation process is greatly decreased by using this insulation material instead of additional primers, waterproofing materials, and fasteners.
The range of uses for polyurethane foam is very broad:
- interior rooms of residential buildings;
- external walls of buildings;
- roofs;
- attics;
- loggias and balconies;
- bathhouses;
- garages;
- sewer systems;
- floors and foundations.
In order to independently carry out polyurethane foam thermal insulation, one must be proficient with the spraying unit. Initially, you can work with an experienced master to practice on a portion of the outer wall. You won’t have any problems working on the installation if you follow safety procedures. Professional equipment is obviously more difficult to learn how to use, but these days there are small, disposable devices that have a much simpler operating principle.
Balcony insulation technology
Insulating balconies with polyurethane foam
Because the room is small, insulating the balcony with polyurethane foam won’t take long. Because external work requires specialized equipment, thermal insulation is done by hand from the inside of the balcony.
When insulating, the following will be needed:
- aluminum profile for the purlin;
- self-tapping screws and plastic plugs;
- level;
- drill;
- spraying unit;
- insulation components.
Step 1. Surface preparation
Peeling or loose coating should be removed from the balcony’s walls and ceiling. You should also inspect the joints and corners surrounding the windows. Putty and foam fragments can be used to fill in any large gaps. The process of spraying will fill in all tiny spaces and seams. Surface grinding and leveling are not required.
Step 2. Fabrication of purlins
In vertical rows, screw the aluminum profile into the walls and ceiling. Next, use half-meter-spaced horizontal lintels to reinforce the purlins. Make sure the profile is screwed all the way around the window and doorway. Polyethylene film should be used to cover the window, door frame, and communication pipes because the insulation hardens quickly and is very difficult to remove.
Step 3. Spraying insulation
Shake the parts well after opening the polymer-filled box. Attach the hoses to the gun and select a nozzle that has a narrow torch. In order to seal the joints between the walls and ceiling and to process the joints surrounding the openings, first blow polyurethane foam into the gaps. Subsequently, a wide nozzle is fitted, and the insulation is sprayed onto the ceiling. The gun should be held level and smoothly guided along the treated surface, and the application should be consistent.
Following the insulation of the ceiling, the walls are covered in a thicker layer of polyurethane foam to level out any obvious defects or depressions. The insulation layer on flat walls should be as even as feasible. Once the material has been sprayed, carefully remove any excess from the purlins.
Step 4. Finishing
Over the thermal insulation layer, panels made of plasterboard, plastic, or wood are fastened to the profile. If decorative plaster is to be used for the finishing touch, a glass fiber reinforcing mesh is attached to the surface and plaster is then applied on top of it.
Insulating the attic
Utilizing FPU to insulate the attic
As simple as insulating a balcony, insulating an attic can save materials and free up space. It is not necessary to apply an antiseptic or priming mixture to the ceilings or cover them with a film to waterproof them. Should the attic’s finishing call for plasterboard or wool cladding, spray insulation ought to be sprayed in between the rafter beams. This will enable the cladding to be fixed to the base without compromising the thermal insulation layer’s tightness.
If decorative plaster is to be used as the finish, all of the surface, including the floor joists, must be sprayed. Using the installation, polyurethane foam is poured evenly throughout the attic, starting at the joints where the walls and roof meet. It only takes a few minutes for the insulation to cure, so you can begin finishing the room.
Floor insulation
What you’ll need to insulate the floor is:
- spraying installation;
- container with polyurethane foam components;
- cement;
- sand;
- water;
- construction level;
- rule or long rail.
Step 1. Preparatory work
During the building phase, the rough base is cleared of dust and debris, and the joints and seams around the room’s perimeter are sealed with mortar. When repairing a residential home with an insulated floor, you must first remove the top layer, clear any accumulated debris, and assess the strength of the lags. It is necessary to replace any rotted floor sections with new ones.
Step 2. Spraying polyurethane foam
Insulating the floor made of wood
Combine the ingredients, attach the hoses and the nozzle-equipped gun, and begin insulating the floor base. It is not advised to apply polyurethane foam in a single, thick layer; instead, spray two to three layers onto the concrete screed. Insulate the area in between the lags all at once, taking extra care to evenly distribute the composition in the floor’s corners.
Devices for FPU application
Step 3. Screed application and laying of the flooring
The main floor can be installed immediately after the insulation between the lags has solidified. Covering the insulation with a cement-sand screed from above is required if the spraying was done on a concrete base. After mixing the mortar in a container, it is applied straight to the layer of insulation. To prevent slopes or other irregularities, use a level to ensure that the screed is horizontal. A 4-5 cm layer of mortar is applied; a thinner layer of screed will fracture when struck mechanically.
Apply the finish coating after the mortar layer has dried. Due to the high thermal insulation properties of polyurethane foam, carpeting or linoleum can be installed over the screed on a thin substrate.
Basement floor insulation
Good insulation is also necessary in basement spaces, particularly in wet ones. In order to properly insulate the basement floor using thermal methods, you must first keep the surface free of excessive moisture. Bituminous and ruberoid mastic work well for waterproofing floors.
Step 1. Waterproofing
The roofing felt covering the basement floor extends 20 centimeters beyond the walls. To make the base as airtight as possible, the material is laid overlapping at the joints and the joints are sealed with bituminous mastic. The roofing felt around the basement’s perimeter needs to be glued to the walls extremely firmly, so mastic and pressed waterproofing are also applied to the walls’ surface.
A screed is poured over the roofing felt to prevent deformation of the protective layer. If the basement is not excessively wet, you can apply mastic to the brick walls to waterproof them, making sure to cover the joints between the floor and walls to a height of 10 to 15 cm.
Using FPU for basement insulation
Step 2. Application of polyurethane foam
Apply the insulation starting from the corner and working your way towards the outlet after combining the ingredients and attaching the hose. Spraying should be done throughout the basement in three to four layers, staying at the same level.
Step 3. Pouring a concrete screed
Using a level, the insulation’s surface is examined, and any areas with significant height variations are leveled. After preparing the screed solution, evenly distribute it over the polyurethane foam. The solution is spread evenly over the whole area using a rule to ensure that the screed is at least 5 cm thick. Once the mortar on the screed has dried and hardened, tiles, linoleum, or another finish coating can be applied.

Polyurethane foam insulation with your own hands
With good reason, polyurethane foam is referred to as a new generation of insulation. Private home owners have been using this technology for building thermal insulation more frequently in recent years. It is possible to insulate using polyurethane foam with your hands. However, the master has sufficiently studied the technology of applying this material, but only if the required equipment is available.
Insulating with polyurethane foam by hand
Polyurethane foam works well for insulating buildings from the inside as well as the outside of the walls. Due to the material’s many advantageous properties, its usage has increased over the past few years. Still, though. It’s important to be aware of any potential drawbacks when utilizing this kind of thermal insulation.
How polyurethane foam is used for insulation
Almost any surface can be coated with a heat-insulating layer to create polyurethane foam insulation. Taking it seriously and increasing volume. The size of the foam composition increases multiple times. Expanding, polyurethane foam seeps into everything. The walls and roof are impervious to wind and cold because even the smallest cracks form a thick, nearly airtight layer.
The most popular application for polyurethane foam is wall spraying.
It should be mentioned that while spraying is the most popular installation technique, pouring is also occasionally employed. This technology is most frequently applied during the thermal insulation structure production process. The components made of polyurethane foam are only utilized once they have fully solidified, having been poured into specialized molds.
Foam can be used to fill in structural cavities to provide insulation.
If spraying is not an option, another pouring option is to fill individual horizontal areas or voids with a foam composition. This technique is employed, for instance, in situations where the gaps between finished material layers that have been installed or walls that have already been constructed need to be filled.
When two ingredients are combined, foam is created.
Polyol and polysocyanate, two polymers that are typically liquids, are combined to create polyurethane foam. During the spraying process, these ingredients are combined without the presence of air, and when they are heated to a high temperature and exposed to carbon dioxide, they foam.
Because of the high pressure produced, the prepared mixture is fed through hoses to the spray gun and applied to the structure. The foam composition forms an insulating layer of the required thickness by perfectly adhering to the prepared surface and actively expanding.

Properties of polyurethane foam
Both commercial and residential buildings are insulated with this material. The inner surface of roofs, walls, floors, and various partitions are all sprayed with polyurethane foam. It is particularly well-liked for insulating frame building walls.
All surfaces can be insulated with polyurethane foam, including the walls, floors, ceilings, and roofs.
Polyurethane foam has demonstrated its unwavering efficacy as an insulator, waterproofing material, and soundproofing material during the course of its active use. It completely shields the house’s rooms from outside noise, freezing, and moisture intrusion.
The main advantages of polyurethane foam
Thus, some of the amazing qualities of polyurethane foam are as follows:
- Excellent adhesion, i.e. reliable adhesion to virtually any surface, whether it is concrete, wood, metal or roofing from other materials.
- Low thermal conductivity of FPU allows you to keep the accumulated heat in the room, if the insulation is made from the inside, creates a reliable barrier against the penetration of cold air, if the material is sprayed on the outside of the walls.
- Polyurethane foam densely fills all holes and gaps, which contributes to the isolation of the room from extraneous sounds of the street. When spraying it on the inner surface of the roof, the insulator is able to muffle the sounds of raindrops, which is especially important for rooms located in the attic rooms of houses.
Polyurethane foam has good insulating properties as well as outstanding noise absorption.
- This insulator resists the appearance of corrosion on the metal elements of the structure and protects the surface from the negative effects of the external aggressive environment.
- When spraying polyurethane foam, it covers not only large surfaces, but also neutralizes cold bridges, which occur in places where the rails of purlins are located. No other types of material can cover them as reliably, therefore. Even if the insulation is used in mats or boards (for example, minwool or polystyrene foam) cold bridges are still treated with assembly polyurethane foam.
- Spraying can be carried out on the most complex in its configuration of structures, on which it is simply impossible to install conventional insulation materials.
- Polyurethane foam belongs to the difficult-to-combust materials, because one of its components is polyol substance A. The polyol substance A is added to it. One of the flame retardants has been added. Giving the insulation the ability to self-extinguishing, to stop burning even if the material enters the fire zone. Polyurethane foam can only be ignited at temperatures of at least 450 – 500 degrees Celsius.
- Low weight of polyurethane foam allows its spraying on any roofing material from the attic side or on the attic floor without fear of weighting these structures of the building. Not only that, the applied layer of insulation will also give them additional rigidity after full curing .
Video: the use of polyurethane foam for roof insulation
- The material when sprayed forms a seamless surface, which can not be done with other insulation materials, without using additional means for their connection (mechanical or adhesive).
- Polyurethane foam is applied very quickly, in a short time expands and hardens. Therefore, the whole process of insulation will take a little – just one ÷ two days, depending on the area and complexity of the insulated structures.
- Due to the moisture resistance of polyurethane foam and the ability to seal the surface, its application eliminates the need to use a vapor barrier and windproof film .
- Polyurethane foam is not subject to rot, mold formation, damage by rodents and insects.
- Leading manufacturers set the guarantee for the service life of polyurethane foam at 50 years. However. Judging by its components and application technology, the insulation will last much longer without losing its qualities, if the spraying of polyurethane foam and its external finishing are arranged correctly.
- Such high performance does not have any existing insulation material, because none of them does not have such adhesive properties.
Material disadvantages
It is hard to discuss the drawbacks of polyurethane foam without mentioning them, both in terms of self-insulation and ongoing use:
- The big disadvantage of this insulation technology is its price, as the purchase or even rental of equipment for the application of polyurethane foam is not cheap .
- To work on spraying, it is necessary to purchase personal protective equipment – a special suit and respirator, to protect against respiratory tract damage. Be sure to cover all areas of the skin, mucous membranes, eyes.
When working with polyurethane foam, extra safety measures and protective gear must be used.
- In the absence of experience in the installation of such insulation, the work can be delayed for a long time, and its quality will not be guaranteed.
- Polyurethane foam is not flammable, but in contact with fire it smokes strongly. At the same time, the smoke contains a large number of harmful substances for humans.
Never leave polyurethane foam exposed to the sun for an extended period of time as the UV rays "kill" the material very quickly.
- If the insulation is applied on the outside of the building and is not covered with finishing materials, it quickly begins to deteriorate under the influence of ultraviolet radiation, decomposing into monomers that are dangerous to human health.
How to insulate with polyurethane foam
Many people would like to insulate their homes using polyurethane foam on their own, but you should be aware that while this is theoretically feasible, it will actually require specialized tools, supplies, and labor-intensive skills. It should be mentioned that the technological apparatus needs to have specific adjustments made before spraying, and that proper execution is required.
The requirement for specialized equipment to spray polyurethane foam is one of the primary challenges.
If you have an idea of how the entire system operates but don’t have any equipment, you can rent it, but the cost will be high as previously mentioned.
What can be concluded, then? It’s probably simpler to call in a pro with his tools; he can finish all the technological insulation stages fast and efficiently, saving the homeowner from a lot of hassles.
In the event that they choose to test their own resolve, the following aspects of the process must be considered:
This material can be used for insulation in a house that has already been built or during building construction. Furthermore, spraying is done on specific regions or the whole surface. Alternatively, cavities are filled with polyurethane foam if needed.
When performing work, it is important to consider the building’s location because the climate will affect how thick the insulation spray layer is.
The following actions are part of the polyurethane foam insulation measures:
- Insulated surfaces require certain preparation. For example, the walls need to be cleaned of the existing old coating if it is clearly unstable (e.g. old crumbling plaster or peeling paint).
- Next, the wall should be lined with a batten made of wooden planks or metal profiles. The thickness of the guides is chosen depending on what layer of insulation is to be applied to the surface.
Battens for the wall surface
- In addition, the purlins can play a leveling role for the wall. It is mounted on the wall surface according to the level and plumb, and the gaps between its elements are then filled with polyurethane foam, which will fill the irregularities and bring the coating to the proper level.
- Foam insulation is sprayed on the prepared plane with a special gun.
- The intensity of spraying should also be adjusted, because if you need not too thick a layer, you need to adjust the machine so that the composition is sprayed in very small jets. Battens. In this case, it is necessary to make of beams or profiles with a small thickness, as they will determine the thickness of the insulation layer.
- Spraying polyurethane foam always starts from the bottom of the wall, and apply it to the surface between the elements of the purlin .
Spray gun for applying polyurethane foam
- The polyurethane foam is applied in a thin layer, which immediately gains volume. If the thickness of the first layer is not sufficient, another layer of insulation is applied on top of it.
Layer by layer, insulation is applied from the bottom to the top.
- After curing polyurethane foam and leveling of the cured coating on the rails of the purlin by cutting off the protruding reliefs of the insulation, it is possible to install siding, wagons. Nothing prevents to do perform outside and brickwork or plaster the walls of the house.
- If the wall is to be plastered after insulation, it must be covered with a wire mesh. The spraying head can be attached to the battens. Then apply cement mortar to the wall by spreading technique. After its setting and initial curing, it will be possible to apply any leveling composition of plaster, as it will lie well on this basis.
Video: process of self-application of polyurethane foam on the wall
To sum up, we would like to point out that two things are crucial in any insulation project: the caliber of the material used and the expertise of the installer. It is therefore best to leave the task to a seasoned expert who will do the spraying quickly and effectively and spare you from needless anxiety.
Step-by-step instruction of polyurethane foam insulation using a disposable kit "PENOGLAS™ KIT"
The availability of disposable foam application kits in retail stores has greatly broadened the applications of this efficient insulator. It is feasible to complete the task without calling in a group of experts and their tools. It is not advised to work with polyurethane foam without personal protective equipment, which is provided in the kit along with everything else that is required.
One of the most innovative examples of this kind of equipment is a "PENOGLASTM KIT" kit made in the United States.
This "PENOGLASTM KIT-400" kit allows you to install premium thermal insulation on a 20 m² surface with a 50 mm thickness.
With a combined weight of roughly thirty kilograms, the entire set is packed into three boxes. Because everything is so small, a standard passenger car trunk can easily accommodate the entire set for transportation.
The entire kit conveniently fits in any sedan’s trunk.
The following physical and functional attributes of the produced thermal insulation are declared by the manufacturer:
- The system is two-component, giving a foam with a closed cell structure that minimizes possible water absorption.
- The density of the polyurethane foam after full curing is 35 to 40 kg/m³.
- Thermal conductivity coefficient – 0.024 W/m׺C.
- The number of closed cells – not less than 85%.
- The total volume expansion of the "PENOGLAS™ KIT-400" kit is 1 m³, which would correspond to an area of 20 m² covered with a 50 mm thick layer of thermal insulation.
- Full curing time of polyurethane foam – 1 hour.
Included in the kit are:
- Two cardboard boxes, each containing a cylinder with one of the components. Both boxes and cylinders have clear color and letter markings: component "A" is marked in red and "B" in blue. The components are in the cylinders under pressure of 8 atmospheres.
The kit’s design permits all operations to be completed without fully removing the package, so cylinders are not taken out of the boxes during use.
The cylinders remain in the boxes throughout the entire process of working with the kit.
- The third box contains all the accessories, tools and spare parts necessary for the work. In it are stacked:
Everything you might need to assemble and operate the system is contained in the little box.
– A spray gun for mixing the ingredients. The gun is equipped with two transparent, flexible hoses that terminate in union fittings with cap nuts to allow them to be connected to the cylinders. Typically, the hoses are color-coded as well so that you won’t confuse the "polarity" of the connection to the cylinders when you reuse the kit. Every hose is three meters long.
– The gun is equipped with unique, interchangeable heads that have a spray nozzle to atomize the mixed composition. There are ten of these heads in the set.
A tiny pack of silicone grease is included in the kit; it is used to secure the heads to the gun connection and to guarantee a dependable seal of this connection.
A wrench is needed to tighten the union nuts when connecting hoses to cylinders; one is included in the accessory kit.
Goggles, gloves, and a respirator are among the eye, skin, and respiratory protective items in the kit.
The manufacturer has also considered safety precautions; a set of personal protective equipment, such as gloves, goggles, and a respirator, is always included in the basic set.
The "PENOGLASTM KIT-400" system is very easy to use and doesn’t require any special user training. It takes minutes to assemble and get the equipment ready for use. The set is completely self-sufficient, so no external power sources are required. See the instruction table below for more information.
An overview of the procedure that needs to be carried out
What is polyurethane foam
FPU is utilized in a variety of applications, including the following home insulation. It is possible to spray polyurethane foam with your hands if you have the necessary equipment. However, because the equipment is costly, hiring a crew rather than buying it all at once makes sense. The modern best heat insulator is FPU.
FPU production technology
Closed-cell architecture.
What exactly is polyurethane foam, then? It is a two-component polymeric composition, similar to foam plastic, that has a closed-cell structure. Numerous chemical components, including polyesters, emulsifiers, and foaming agents, make up the first component (A). Since none of these substances are toxic or explosive, they are all kept in metal barrels that have been given extra internal protection.
A combination of polyisocyanate and diisocyanate makes up the second component (B). Because these are toxic materials, you should use extra caution when handling them. They ignite at 215 degrees. When exposed to air or water, they lose their properties. Polyurethane foam is produced through a reaction that happens when components A and B are mixed. The ratio of components used in polyurethane foam production techniques varies, which affects the polymerization time, density, and thermal conductivity coefficient.
It’s not realistic to make polyurethane foam at home by hand.
It has to do with getting the parts ready. All you have to do is combine the pre-made (in-house) reagents before applying them to the work surface. And that you will need to purchase a special installation in order to do this.
In the world of home improvement, insulating your house is key to keeping it cozy and energy-efficient. When it comes to insulating materials, polyurethane foam stands out for its effectiveness and ease of application. With just a few simple tools and a bit of know-how, you can tackle this project yourself, saving both time and money. Whether you"re filling gaps in walls or sealing cracks in your attic, polyurethane foam offers a versatile solution that expands to fill every nook and cranny, providing a tight seal against drafts and heat loss. By applying polyurethane foam yourself, you can take control of your home"s comfort and energy efficiency, making it a DIY project worth considering for any homeowner looking to improve their living space.
Scope of polyurethane foam
Polyurethane foam comes in two varieties: soft and hard. The foam used to make mattresses, furniture cushions, and other items is called soft polyurethane foam. Car seats and military equipment parts are made using rigid FPU. Polyurethane foam has been more and more popular lately as an insulator in civil construction.
A specific gun and compressor are needed for spraying.
In order to create insulating boards, it is sprayed onto both horizontal and vertical surfaces. Special tools are needed to spray polyurethane foam with your hands; we’ll go over them later. Pipe insulation is another application for FPU. Certain steel pipes have protective polymer covers and polyurethane foam coverings. These products are employed in underground communication installations. Furthermore, shells with varying diameters are produced to insulate utilities from heat.
Panels are made of polyurethane foam:
- sandwich – when the insulation is covered with profiled tin on both sides;
- facade – the thermal insulation is covered with a decorative layer. It is impossible to distinguish from a natural stone or clinker tiles .
Liquid polyurethane is blown into the spaces between the walls during the civil construction process. This can be carried out both during the construction of the surrounding structure and once the job is finished. This material’s benefit is that it fills every void, resulting in a monolithic carpet that insulates against heat.
Insulating a home with polyurethane foam can significantly improve comfort and reduce energy costs for homeowners. It is a feasible choice for do-it-yourselfers because of its remarkable insulating qualities and simplicity of application. Polyurethane foam is an effective gap-sealing and home-insulating material for homeowners who follow easy instructions and take the appropriate safety measures.
Whether it is used for attic and crawl space insulation, wall crack sealing, or gap filling around windows and doors, polyurethane foam provides a flexible solution for a range of insulation requirements. Due to its ability to expand, it can fill even the smallest gaps and conform to irregular shapes, giving a complete seal against heat loss and air leakage.
The high R-value of polyurethane foam, which denotes its thermal resistance, is one of its main benefits. By effectively blocking heat transfer, homes are kept warmer in the winter and cooler in the summer. Enhancing insulation helps homeowners save energy and money on utility bills by lessening the strain on their heating and cooling systems.
Applying polyurethane foam can also help create a home that is more sustainable. Homeowners can lower their carbon footprint and save money by consuming less energy. Appropriate insulation promotes environmental responsibility by lowering greenhouse gas emissions from energy production and assisting in resource conservation.
To sum up, installing polyurethane foam offers a practical and affordable way to insulate a house. Thanks to its exceptional insulating qualities and do-it-yourself approach, homeowners can improve the comfort and energy efficiency of their living spaces. Polyurethane foam helps create a more sustainable and eco-friendly home environment that benefits both occupants and the environment by sealing air leaks and improving thermal resistance.
