Choose plastic air ducts for ventilation: Features and nuances of installation

Proper ventilation is essential to creating a cozy and effective living space in our houses. An efficient ventilation system contributes to a healthier and more comfortable environment by controlling temperature and moisture levels in addition to maintaining indoor air quality. The air ducts are a vital part of any ventilation system because they are responsible for distributing air throughout the house. Because of all of their benefits, plastic air ducts have become a more popular choice for ventilation systems in recent years.

Comparing plastic air ducts to conventional metal ductwork reveals a number of advantages. Their lightweight design, which makes them simpler to handle and install, is one of their main benefits. Plastic ducts are more flexible and can be easily manipulated to fit into tight spaces or around obstacles, unlike metal ducts, which can be heavy and require special tools for shaping and cutting. This flexibility lowers the overall labor and time required, while also simplifying the installation process.

The fact that plastic air ducts are resistant to rust and corrosion is another important benefit. Plastic ducts are incredibly strong and long-lasting, in contrast to metal ducts, which rust and deteriorate over time. Because of its longevity, the ventilation system won’t require regular maintenance or replacement and will continue to operate effectively and efficiently for many years to come.

Plastic air ducts are not only long-lasting but also resistant to mold and moisture, which makes them a great option for places like bathrooms or basements that frequently experience high humidity levels. Plastic ducts have a non-porous surface that keeps moisture from absorption, lowering the possibility of mold and mildew growth inside the ductwork. This extends the ventilation system’s lifespan and contributes to the maintenance of indoor air quality.

In addition, plastic air ducts come in a range of sizes, shapes, and configurations to accommodate various HVAC systems and installation needs. Round, oval, or rectangular ducts are all possible, and plastic options are flexible and adaptable to fit a range of layouts and styles. Plastic ducts can also be readily customized or altered on-site to satisfy particular project requirements, which increases their applicability for a variety of uses.

All things considered, plastic air ducts are a very attractive choice for homeowners trying to upgrade their ventilation systems. Plastic ducts are an economical and practical way to achieve the best possible indoor air quality and comfort because of their many benefits, including lightweight design, resilience to corrosion and mold, durability, and adaptability in construction. Homeowners can reap the long-term advantages of a well-ventilated and healthy living space by selecting plastic air ducts for ventilation.

Plastic air ducts: what materials are made of

• PVC (polyvinyl chloride). Has a wide temperature operating mode from -30 ° C to +70 ° C. PVC air ducts can be installed in unheated rooms.
• PVDF (fluoroplast). acid -resistant material with a wide temperature range -from -40 ° C to +140 ° C.
  An example of ventilation from plastic ventilation pipes in the bathroom
• PP (polypropylene). It is characterized by increased resistance to chemical effects (tolerates acids, alkalis, organics).
• PND (low pressure polyethylene). This material is characterized by increased flexibility, it is more difficult to damage it mechanically, but does not tolerate low temperatures.

Consideration should be given to the properties of plastics when selecting plastic ducts. For instance, connecting a kitchen hood with polypropylene ducts is preferable. PVD or PVC air ducts work well if the discharge air has a high temperature. Polyethylene boxes are ideal for wiring ventilation in residential and other technical buildings.

Types of plastic ducts

Depending on the following factors, all plastic air ducts used to make ventilation ducts can be conditionally classified into multiple types:

• manufacturing material;
• type of section;
• degree of stiffness;
• the method of connecting elements among themselves.

Different polymer compounds that are appropriate for these uses are used as the primary material for plastic ducts:

• polyvinyl chloride (PVC);
• fluoroplast;
• polypropylene;
• low-pressure polyethylene;
• viniplast;
• Metal -plastic.

Nowadays, polyvinyl chloride is widely used in the production of different types of pipelines. High strength and resistance to corrosion influences are two of its key characteristics. The operational temperature range is between -50 and +90 °C. PVC maintains its functional properties and does not distort within these bounds.

It wasn’t until recently that fluoroplast was used in the production of pipes—particularly ventilation ducts. This material’s primary benefit is its ability to withstand the harsh effects of chemically active media. Businesses such as oil refineries, chemical plants, and pharmaceutical companies, where there may be a concentration of different chemical vapors in the air, can effectively use fluroplast air ducts.

Fluoroplast has the highest sliding coefficient of any polymer, which is an additional benefit. Consequently, there are almost no turbulent turbulences in the air that flow through these pipes, making fluoroplastic air ducts the most efficient on record. Fluoroplastic air ducts operate in the temperature range of -100 to +250 °C.

The budget value is the primary benefit of the polypropylene air pipelines. They can quickly tolerate the transported air’s temperature rising to 110 °C without deforming or losing their properties. However, polypropylene starts to melt at 140 °C. The high combustibility of this material is another disadvantage. As a result, it is not permitted to ventilate rooms with open fire sources using polypropylene air ducts, such as kitchens with gas boards.

Foamed polymers are used to fill the space between the two layers of thin tin, or galvanized steel, that make up the intricate structure of metal-plastic air ducts. The protective role of the metal shell shields the ventricans from mechanical harm and eliminates the risk of fire from brief exposure to open flames.

Take note! The only rooms where using plastic ventricans is allowed are those without a direct fire hazard. GOSTs and SNiPs strict guidelines should be strictly followed when installing plastic air pipelines.

Dimensions and shape of the section

The sections of plastic ducts vary in size and shape. The number of people inside and the internal volumes of the ventilated premises determine the diameter of the section that is chosen. As a result, the ventilation duct’s capacity to remove air per unit of time increases with its diameter.

Air exchange indicators in residential apartments must be at least 30 cubic meters per person per hour in accordance with SNiP regulations. In an hour, a pipe with a diameter of 15 cm can be removed with this much air and natural ventilation.

Plastic ventilation ducts are available in home building material stores, typically measuring between 10 and 20 centimeters in diameter. The most typical sizes for ventangle ventricular ventilations range from 10 x 5.5 cm to 20.4 x 6 cm. Larger diameter and plastic air ducts are possible in certain situations.

For instance, consider how the ventsistems are arranged in sizable retail, entertainment, and office buildings.

Polymer air ducts come in two shapes: round and rectangular, depending on the section type. The experts say there is no fundamental difference between them. Despite this, it is thought that air is evacuated more quickly through round ventilation channels because they have fewer turbulent twisting bends than rectangular ones.

These two air pipelines are identical in terms of cost and lack any unique characteristics. There are occasionally elliptical-shaped plastic ducts available.

Review and characteristics

Different plastic types are used to make plastic ventilation boxes, which vary in size, shape, and stiffness.

A large selection of fittings and connecting components make it simple to combine them into a single design.

What are plastic ducts make?

Details of plastic ventilation systems are formed without seams under the influence of high pressure. Various polymer groups are utilized as raw materials:

• Polyvinyl chloride (PVC). PVC pipes are absolutely safe for human health, resistant to ultraviolet radiation, resistant to alkalis, mineral oils, many types of acids and alkalis, are not ignited when exposed to open fire. The operating temperature interval is from -15ºС to +66ºС.
• Fluoroplast (PVDF). Retains strength and elasticity at temperatures in the range from -70ºС to + 140ºС. Fluoroplast products are thermo -resistant, immune to the effects of aggressive acids and alkalis, resistant to moisture, are well treated with cutting, drilling, milling.
• Polypropylene (PP). Polypropylene ventilation boxes are resistant to high temperatures (t melting is 175ºС), steam – and gas -resistant, wear -resistant, have high shock strength, resistance to multiple bends.
• Low -pressure polyethylene (PND). The ducts are not subject to decay, rust, do not crack from exposure to low temperatures, hydrophobic, elastic, can be used for the manufacture of ventilation systems even in buildings with a complex configuration.

When selecting plastic air ducts for ventilation system arrangement, you should consider the technical properties of plastics in addition to their price. Products made of polypropylene, for instance, can be used to build range hoods over kitchen stoves.

It is preferable to use PVDF or PVC pipe when the diverted air (chimneys) is heated to a high temperature.

In technical and residential buildings, ventilation boxes can be installed from PN.

Advantages and disadvantages

The benefits of plastic air ducts are rather numerous and include:

• environmental safety;
• mechanical strength;
• plasticity;
• resistance to chemically active and organic substances;
• resistance to temperature changes;
• small specific gravity;
• moisture resistance;
• not subject to corrosion;
• Easy in installation and maintenance;
• a large assortment of sizes, shaped elements and fittings that allows you to collect a system of any configuration;
• wide color palette;
• affordable price.

The fact that plastic boxes for ventilation blend in nicely with any interior decor without taking up unnecessary space is one of their key benefits.

Plastic products don’t need extra finishes once they’re installed. Smooth-formed, aesthetically pleasing air ducts are a great addition to both office and residential buildings.

Additionally, the smooth inner and outer surfaces of durable plastic ducts prevent air flows from being obstructed as they pass through them.

Warm soapy water is a simple way to remove the fat plaque that has, in one way or another, developed on the inside walls of the box.

Their primary drawbacks are:

• Low fire resistance. Only metal boxes are not affected. Although not all plastic (for example, fluoroplast) can burn and spread burning, but the cost of fluoroplast products is quite high. Therefore, the installation of air ducts from other types of plastic is allowed only in low -rise buildings.
• The ability to accumulate a static charge, leading to sticking fine dust, which can ignite. It is especially assembled on corrugated pipes, so such air ducts are equipped with filters that prevent dust from hitting, and also processed with a special mixture. It forms a thin film on the surface, which reduces the accumulation of a static charge.

Where they use?

Devices that use plastic ventilation boxes include:

1. natural ventilation. The ventrical mine is equipped in the supporting internal walls of the kitchen with a roll through the roof. The supply valves are mounted in the window blocks of living rooms. I ventilation of the room is carried out due to the receipt of fresh air from the window valves, which moves towards the zone of discharged pressure (to the kitchen), ventilating the corridor along the way;
2. the supply system supplies to the room, with the possibility of heating in the winter season. With this type of ventilation, the channel is created in the wall of the kitchen or assembled in the form of a wall structure, and the supply silent fan is cut into the outer wall of the room;
3. an exhaust system that removes the exhaust air from the room, as well as the products of combustion of natural gas from gas devices.

The section of plastic ducts and their dimensions

Ventilation boxes made of plastic produce:

• Round section.
• Rectangular section (rectangles and squares).

Every species is resilient and adaptable. Special forms are cast for hard boxes. With the exception of geometric sizes, their primary feature is wall thickness. The thickness of the wall should be 3 mm so that the plastic air duct maintains its shape. Greater weight and a notably higher price are associated with more thin bending and thick walls.

Plastic ducts that are flexible are the second kind. produced using a corrugated form. To seal the wire itself in plastic, a layer of plastic is wrapped around the wire frame. Because you can bend them at any angle, these air ducts are simpler to install.

Corrugated semi-rigid ducts

One piece of corrugated plastic pipe for ventilation can be up to 2.5 meters long, allowing for the creation of short routes using only one complete piece. The installation was quite easy: they were placed out on the highway, fixed in multiple locations, and fixed from both ends. Stretching the corrugation as much as possible will help to lessen air flow resistance and wall irregularities.

However, air movement remains challenging even in well-stretched corrugation because of uneven walls. Corrugated ducts are therefore positioned larger when all other factors are equal. Furthermore, dust, fat, and grime gather more quickly on uneven surfaces. Walls are extremely thin and weak mechanically. Options that are semi-rigid are more dependable (as in the above photo). They are more dependable but bend more easily.

Round plastic air ducts

Typically, round plastic air ducts are made of:

• 100 mm;
• 125 mm;
• 150 mm;
• 200 mm.
  and round and rectangular plastic ducts can be large

However, industrial spaces can accommodate much larger sizes, reaching up to 2.4 meters in diameter. The segments of round ventilation pipes come in sizes of 500 mm, 1000 mm, 1500 mm, 2000 mm, and 2500 mm for sale.

Cross -section of rectangular ventilation pipes

The following sizes of rectangular plastic ducts are available for residential use:

• height – 55 mm, 60 mm;
• width – 110 mm, 122 mm, 204 mm;
• length – 350 mm, 500 mm, 1000 mm, 1500 mm, 2000 mm and 2500 mm;
• wall thickness-2-8 mm.
  An example of dimensions of plastic rectangular pipes for ventilation

The walls of the plastic ventilation pipe are thicker the larger it is. This is required to prevent the geometric dimensions of the products from changing. For shorter walls (as shown in Figure A), the thickness can be reduced to 2-3 mm, while a wider area (shown in the photo) can be thickened to 3-5 mm.

Which is better: a round or rectangular duct?

Which type of air duct is superior? Square or round? It is better round if you take it by bandwidth. They have less resistance to vortex flows, which allows air masses to move more quickly. Corners in rectangles stay nearly unjustified. As a result, rectangular shapes have a larger cross-sectional area than round shapes.

Even the "at the top" in this incarnation was hardly noticeable.

Rectangular plastic pipes are more frequently used for ventilation even though they have the worst qualities. They can be more easily concealed by lowering them, as in the case of hinged cabinets. Additionally, since some models are flat and wide, they need to be arranged at a lower height when using a stretch or hinged ceiling. The rectangular box at the intersection of the wall and ceiling looks better than the round one, even in the absence of a false flow and without any place to conceal the ventilation.

Which plastic is better?

The question of which pipe is better or worse cannot be objectively answered by anyone. Truth in absolutes does not exist. The only thing that can accurately determine which pipes are better to install, how long the installed ventilation will last, and when to expect a return on time, energy, and financial investments is experience.

Polyethylene pipes

Designs are mostly utilized in suburban buildings and houses used as vacation homes on dachas. Both indoors and outdoors, polyethylene with a protective layer is utilized. Making the connecting holes in it is simple.

The material is more resilient to air drops at both high and low temperatures than PVC. Easily withstands "minus" temperatures of -45ºΡ / -50ºΡ and "plus" temperatures of +80ºΡ / +85ºΡ. Ventilation pipes made of polyethylene can be operated within the range of -45 º to +75 ºΡ without causing any harm.

Produced using an antistatic and ultraviolet coating. have a different color from other plastic products and contain black soot.

Polypropylene pipes

Products started to be produced in Russia during one of the crisis times. Wonderfully dielectric, non-hygroscopic, and highly resistant to harsh chemicals is polypropylene. The strength of the strength is roughly four times greater than the comparable polyethylene product indicator.

Three primary factors that explain the PPR-pipe’spopularityand connection to widely used equipment are as follows:

1. Cheapness,
2. Simple installation;
3. The availability of tools.

In a word, it’s an inexpensive, high-quality pipe. It is more affordable than some manufacturers. However, by European standards, polypropylene pipes represent the final phase of construction. Certain criteria state that the material is morally out of date and does not fit the category of fire-resistant materials.

• The main drawback is that it burns and melts if the temperature exceeds the established norms: +85ºС/ +90 ºС;
• To raise combustion resistance, special non -combustible and antistatic additives are used;
• At negative temperatures, the material becomes brittle, therefore it is used only in warm rooms.

Not every manufacturer has thoughtfully designed nozzles and a pipe docking system for the pipe. During operation, additional noises appear and flows form. When handling polypropylene, extreme caution is required. At high temperatures, the pipe expands dramatically.

The primary market for polypropylene pipes is beginners or people without access to more expensive professional supplies. Perfect on a tight budget.

Regarding the service life of plastic, manufacturers and retailers cannot agree more. Although well-known brands have been around for a while, polypropylene pipes are the least useful technology. It is generally worthwhile to factor in a 20-year period.

Polyvinyl chloride

Lightweight, reasonably priced, and easy to install air ducts The most popular material for building ventilation structures in daily life is PVC. Polyvinyl chloride equipment is particularly in demand among owners of small cottages and apartments because it is affordable, practical for installation, and simple to operate.

They have a wide enough operating temperature range (from 0 to +80 degrees) and are shielded from UV damage. Like most plastic products, the manufactured models are robust and sealed, but they have certain drawbacks:

• Crack over time;
• Do not heat up to 160 ° C;
• Do not tolerate negative temperatures.

PVC products can be heated to +120 °C without endangering health. Chlorine starts to stick out if above.

Fluoplast pipes

The most resilient material that can withstand environmental factors and external forces is fluoroplast. PVDF is installed in the exhaust and supply air regimes.

Pipes have the capacity to endure:

• Contact with pairs, acid-base solutions;
• Safe exposure temperature from -40 ° C to +140 ° C.

Aggressive air masses enter and exit through fluoroplast air ducts. The material performs admirably in the task.

Plastic pipes have a shorter service life at higher temperatures and pressures.

Thus, every kind of material produced and portrayed in the global industry is functional. Fluoroplast and polyvinyl chloride are more frequently utilized for installing home ventilation systems than polyethylene and polypropylene.

Other selection criteria

The inner surface of plastic ventilation ducts should be considered when selecting them; it should be smooth. In this instance, there will be efficient air circulation.

One key sign of a high-quality material is its flexibility. If the element is too hard, it will be harder to mount and have a shorter lifespan.

Diameter

There are standards for both residential buildings and sizable manufacturing facilities, based on which the ventilation system’s throughput is determined.

Three primary sizes are utilized in apartments and small buildings:

• high power extract or ventilation with constant air circulation – 100 mm;
• a small power system designed for periodic ventilation of the room – 125 mm;
• rooms where people are constantly located, offices – 150 mm.

As per the regulations overseen by SNiP, the minimum air exchange frequency for houses and apartments is 0.5 cubic meters per hour. This criterion must be considered when choosing the air duct’s diameter.

There are ventilation bandwidth standards for residential buildings.

Corrugation or not

It’s not essential to use just pvc or corrugated pipes for the hood to function properly. It is acceptable to assemble structures made up of various channel kinds. What matters most is that the system’s throughput meets the required thresholds.

Corrugation offers a number of benefits over plain plastic, including:

• the ability to lengthen or squeeze the channel within small values without adding or removing elements;
• installation at any angle;
• low cost.

Plastic has a more attractive appearance. After installation, decorating is not necessary.

The quality of the material

The company’s product is either gray or white in color. The components bear the manufacturer’s marking, and the price cannot be less than what the market will bear.

Plastic channels ought to be pliable and able to retain their shape even under light compression. In certain places, burrs, cracks, and deformations are unacceptable.

The color of the ventilation duct is white.

Technical characteristics and dimensions

Air ducts with a PVC foundation are composed of a unique ABS plastic. He is allowed up to 4%. Among the other advantageous traits are:

• lack of need in the addition of the thermal insulation of the roof;
• accessibility of independent adjustment;
• small probability of corrosion;
• smooth inner surface, due to which there is no probability of static resistance when air passes;
• reduced loss of noise and air;
• service life – from 20 years or more.

Since plastic burns easily, it is not advised to place anything close to the chimney. Preference must be given to galvanized products if greater fire protection is needed. Regarding dimensions, the subsequent characteristics stand out:

• Most often, buyers purchase round ducts with a diameter of 1, 1.25, 1.5 cm. In accordance with GOST, their section should be 200 cm.
• The plastic air duct of the rectangular section has standard dimensions 55 by 110, 60 by 120 and 50 by 204 mm.
• 20 m is the length of flexible ducts.

The components of the kitchen hood are mostly composed of plastic. It is highly recommended by experts to install plastic on exhaust ventilation ducts. Here, there are no limitations. However, the inflow is necessary for goods made of a unique kind of plastic that can withstand heat effects. This is particularly valid in the event of heating or recovery.

When selecting plastic air ducts, you must consider the features of a single space. It is not always advised to use the fire service because of possible issues. This is important, for example, if the ventilation system is composed of plastic. You ought to use caution and a frame home.

It is best to get in touch with the local fire inspector if you have any questions. Regulatory documents also contain pertinent recommendations. They specify that these items may be used in public areas, low-rise residential areas, and administrative zones. They are also not allowed in technical floors, basements, or attics.

Classification of products

The four primary types of ducts are flexible, square, rectangular, and round. In the first example, the ventilation system routes are set up using products. These objects range in diameter from 1 to 1.5 cm. Rectangular plastic ducts are frequently used in residential settings. They are positioned beneath the suspended ceiling’s area.

Air ducts made of plastic These measurements are standard, measuring 60 by 120 and 60 by 204 mm. Flexible sections are not like round or rectangular sections. Everything is dependent upon the potential needs for this variety. These objects are not longer than 20 meters.

Rectangular plastic pipes are simple to install on the walls and ceiling. They are perfect for this. However, a round section causes the throughput to rise. Another name for the plastic flat duct is rectangular. The pipe’s height, which is significantly less than these objects’ width, explains this. There will be special components needed in order to collect such a duct. The channel is at least 35 cm long and extends to a distance of 2.5 m.

Extrusion is the process used to create flexible pipes. They are manufactured using automated equipment. Because of this, the price of completed goods is low. Low resistance prior to low temperatures can be highlighted here. The pipe becomes brittle if the temperature drops below the 10-degree Celsius indicator. Plastic reacts to heat exposure in a similar way. However, the fire safety system steps in to save the day. Viniuretan is used to create adaptable changes. Steel spiral is welded to polymer.

It is very difficult to damage a flexible reinforced pipe. It offers a respectable degree of noise insulation. Its great suppleness fully justifies its name. It can even tie a knot in certain situations, which keeps it from losing its functionality. Or to put it another way, round, cylindrical pipes are found in both residential and commercial settings. Compared to rectangular models, they pass air flows much more effectively; however, their installation method may not be as comfortable to use.

Installation and embedding in the cabinet

It is sufficient to possess even a standard hacksaw in order to gather the duct. Sealant is used in the process of system insulation. If necessary, components for joining separate pieces can be purchased. Metal and plastic pipes can both be used for ventilation at the same time. Usually, the latter are positioned at the output, and dampers for plastic goods are extracted from them. You can use the fan to quicken the air flow in the pipes. Remember that a high number of bends intensifies the craving. If a turn occurs, the ventilation power is decreased by ten percent.

When setting up an air duct and hood, integration within the cabinet may be possible in certain situations. I have to install the check valve in front of the ventilation shaft in order to accomplish this. Additionally, the following is the action algorithm:

1. Make a hole for the ducts with a jigsaw in the shelves and walls of the cabinet.
2. Draw a pipe into the obtained hole, fix the joints with a sealant.
3. Hang the cabinet on the wall, connect the duct with the ventilation shaft, fix it with self -tapping screws.

Features of design and installation

Without the assistance of a specialist, one can install a plastic box to control the ventilation from the kitchen hood on their own. In this situation, it’s important to consider a few basic aspects of how these systems are designed and installed.

There are several standard steps in the installation of the plastic system that must be completed by both hired laborers and an independent master who chose to construct the box by hand.

Stage #1 – selection of the geometry of the ventilation system

Almost any geometry of a plastic ventilation box can be realized thanks to a large selection of structural elements.

When designing the air duct, the following guidelines need to be followed in order to maintain the air passing system’s functionality at the appropriate level:

1. The length of the box. If possible, it is necessary to minimize the length of the box. The optimal distance from the hood pipe to the ventilation grill is considered a distance of less than 3 meters.
2. Less elements. It is advisable not to use a large number of elements that change the direction of air movement. Bends, narrowing and various transitions create additional aerodynamic resistance.
3. A minimum of turns. It is necessary to minimize the number of knees with a rotation of the box by 90 degrees. They create the greatest resistance to the movement of the flow, generate noise and accumulate deposits in the form of fat and dust adhering to it.

It is important to keep plastic from heating up to more than 50 degrees Celsius if the box is positioned close to a heating riser or other heat source.

Either avoid the hot object or place thermal insulation between it and the air duct in order to accomplish this.

Polystyrene is the most convenient material to use as an isolation because of its low thermal conductivity. Furthermore, he won’t make any noise when the box vibrates.

Installation of a heating riser with four 90-degree-angled knees. If the channel were oriented differently and its narrow portion faced the wall, it would be feasible to use a multi-sided knee to get by at angles between 15 and 20 degrees.

Stage #2 – installation of a check valve and grille

A check valve is an essential component of the ventilation system, and its importance cannot be overstated.

The valve is placed at the end of the duct if the box only branches to the mine from the hood and does not go to any other sources of air fence. Using a lattice with a check valve to stop air return is an additional choice.

When there are multiple air fence sources in the ventilation system, a check valve is placed close to where each branch connects to the main air duct and another close to the lattice.

When there are two air fence points and an outer grate in the ventilation system, a conventional method for installing check valves

In the event that natural ventilation is required, there are three options available when the hood is off:

• divide outputs for forced and natural ventilation, and they should not go into one ventilation shaft;
• install the tee “hood – lattice – check valve” near the exit;
• use a ventilation grill with slots for natural air movement and protection against reverse traction.

Sometimes rodents or birds that reside in a ventilation shaft will make their way inside the duct. They may perish once inside the plastic box’s bends, which would cause decomposing materials to spill into the space.

In order to stop this kind of thing from happening, a lattice that leads to the mine or the street is frequently equipped with extra security that animals cannot get past.

This article provides comprehensive details on the varieties and choices of ventilation grilles.

The section is considerably narrowed when the ventilation grill is protected from birds and rodents, so this must be considered when determining the hole’s diameter.

Stage #3 – fasteners and air duct placement

Depending on where they are in relation to the cabinets, walls, and ceiling, the plastic duct sections that run from the hood to the ventilation grill can be fixed in a variety of ways.

Any option can be independently installed, and it is not difficult to do so.

To prevent vibration noise, box sagging or other deformations that could lead to a depressurization later on, and other potential problems, this procedure must be handled carefully.

If the box is inside the cabinets, clamps are used to mount it to the back wall of the cabinet. Also, use polystyrene or polystyrene foam inserts to seal the duct’s passageways through the walls.

When these materials come into contact with the system’s vibrating components, they don’t create any noise.

If there is a section of the air duct above the cabinets, the simplest method to attach it to the cabinets is to use self-tapping screws and holders for a short length. In its current configuration, the plastic box exerts negligible side pressure.

It is recommended by the holders that the duct be fastened to the wall or ceiling after one meter. Special clamps, which are available under the dimensions and form of the purchased box, are used for fixation.

The entire plastic structure weighs little, making it simple to assemble.

The plastic box can be fully concealed by covering it with drywall and suspending ceiling. In this instance, sealing and fastening the entire structure without considering how it appears visually is acceptable.

When the hood is running at maximum power, it is necessary to verify the stability of the fixation if the plastic box is closed by a stretch or suspended ceiling. In other situations, once vulnerabilities are identified, the mount can be readily reinforced.

Occasionally, when the ventilation system is operating, solid objects like cabinets or walls may come into contact with the vibrating components of a plastic box, causing a knocking or rattling sound.

In this instance, placing a piece of foam in between them suffices in place of additional fastening.

When it comes to heating and insulating your home, choosing the right materials and systems is crucial for efficiency and comfort. One key aspect often overlooked is the ventilation system, which plays a significant role in maintaining air quality and regulating temperature. Plastic air ducts offer several advantages over traditional metal ducts, including flexibility, durability, and resistance to corrosion. Understanding the features and nuances of installing plastic air ducts can ensure optimal performance and longevity for your home"s ventilation system. From proper sizing and layout to sealing and support, careful attention to installation details can make all the difference in maximizing airflow and minimizing energy loss. Whether you"re upgrading an existing system or installing a new one, opting for plastic air ducts can be a wise choice for enhancing your home"s overall heating and insulation efficiency.

Flexible corrugated ducts

A flexible corrugated duct’s wire spiral frame serves as its foundation. It is twisted into aluminum polyester or vinyl chloride thermoplastic polymers, which are strong but elastic materials. Also flexible air ducts made of plastic, but not corrugated. These days, virtually every ventilation system has a flexible polymer air duct installed.

Advantages of flexible ducts

Benefits of a flexible air duct for ventilation:

• ease of installation;
• if necessary, you can quickly perform dismantling;
• convenience during the performance of maintenance or repair work;
• Transportation that does not cause difficulties, as well as warehouse storage;
• small weight;
• ease in changing the direction of the route of the flexible ventilation duct;
• low price.

Ventilation ducts and their varieties

Flexible and corrugated plastic ventilation ducts can be installed in locations where the duct meets certain requirements, in addition to locations where they must be bent.

Classification of corrugated ducts

1. Thermal insulated. They have ordinary or increased resistance. Their inner layer is thermal insulation.
2. Unenviated, come with ordinary or increased resistance.
3. Soundproofing, inside such air ducts there is a perforation that absorbs sound.

Features	Nuances of Installation
1. Lightweight and Durable	2. Proper Sizing and Placement
3. Easy to Clean and Maintain	4. Ensure Proper Sealing for Efficiency

There are several advantages that plastic air ducts for home ventilation systems can provide. Because of their light weight, they are simple to handle during installation, which saves money and time on labor. Furthermore, plastic ducts are long-lasting and durable because they are impervious to moisture and corrosion. These characteristics make them especially appropriate for use in bathrooms and kitchens, which are frequently subjected to high humidity levels.

Plastic air ducts offer versatility and flexibility in terms of installation. They are simple to resize and arrange to match the precise design of the ventilation system in your house. Greater customization is possible thanks to this adaptability, which guarantees ideal airflow throughout the property. Plastic ducts provide an adaptable solution for installing new systems or retrofitting existing ones to meet specific requirements.

The smooth interior surface of plastic air ducts reduces airflow resistance, which is another benefit of using them. This encourages effective ventilation, which lowers energy use and utility costs. Furthermore, compared to metal alternatives, plastic ducts are less likely to gather dust and debris, which enhances indoor air quality and lowers maintenance requirements.

To sum up, plastic air ducts provide an affordable and useful upgrade for home ventilation systems. When looking to improve indoor air quality and airflow, homeowners find them to be an appealing option due to their lightweight construction, flexibility, and resistance to corrosion. For your ventilation needs, plastic ducts offer a dependable and effective system that will perform well for many years to come.
