How to insulate a hangar: options for insulating prefabricated structures. Effective insulation of hangars, warehouses and vegetable stores

Effective insulation of hangars, warehouses and vegetable stores. Prompt measures and longevity of the result The success of an enterprise, the economic well-being of individual companies, cities or even countries depends not only on the level of production development, but also on how long they can store the products produced. In simple terms small example this becomes obvious. There is no point in storing for the winter a large number of vegetables and canned goods if they cannot be provided with the correct storage conditions. They'll just go bad.

Therefore, a combination of factors such as temperature and humidity conditions, the presence or absence of sunlight, fresh air flow, as well as many other nuances directly affect the shelf life of raw materials or products, regardless of their types. Hangars, warehouses, and vegetable storage facilities must fully meet certain requirements dictated by the types of products stored in them. It is very important to maintain constant conditions in the hangar, warehouse or vegetable storage area at any time of the year. And not everyone can achieve this.

Only proper insulation and thoughtful design can have a positive impact on the operation of the facility.

Only proper insulation and thoughtful design can have a positive impact on the operation of the facility. With minimal energy consumption, the owner of a warehouse or hangar has the opportunity to maintain optimal conditions for storing certain raw materials or products for a long time. But how to insulate such a large structure without missing anything or making mistakes with materials? The answer is simple - entrust this matter to professionals.

Varieties of warehouses, hangars and vegetable storage facilities. Their design features and resulting requirements for insulation materials

To begin with, it would be correct to consider the most commonly used types of hangars, warehouses and vegetable stores. This will allow you to better understand what kind of insulation materials need to be used.

Hangars

This type of facility is often used to store various types of machinery and equipment. These can be agricultural machines, aviation equipment and much more. The features of hangars include the following:

Hangars are often used to store various types of machinery and equipment. These can be agricultural machines, aviation equipment and much more.

• They are distinguished by their large scale - the height, width and length of the hangar should allow it to accommodate large equipment
• The use of vaulted roofs - for hangars this optimal design. Essentially, this avoids the need to build walls, but when building large hangars for certain types technicians can also lift the walls on which the vaulted roof is mounted
• Use of thin sheet materials - thin sheet steel is often used for construction, with which the metal frame is sheathed. This allows you to reduce costs when constructing such large objects

Old hangars can be lined with wood. But today this is very rare. Design features This type of objects themselves dictate the requirements that the insulation must meet:

• It should easily adhere to thin metal surfaces
• Must be able to withstand dynamic thermal deformations of the base well, since the metal reacts very sensitively to temperature changes
• It must be highly efficient - in fact, it will not only insulate, but make up 95% of the thickness of the entire wall, so it must be as efficient as possible
• Have a small weight - the vaulted roofs of such hangars are designed for certain loads, so they cannot be overloaded. And given the scale of the structure, the use of heavy insulation is simply unacceptable

Warehouses

This concept is very broad, since a warehouse can be built from almost any building materials, its configuration can be anything, and it itself can be only a small part of any large real estate complex. At the same time, almost any goods, raw materials or equipment can be stored in warehouses. Thus, no less requirements will be placed on the insulation. In addition to what has already been announced for hangars, we can mention:

Almost any goods, raw materials or equipment can be stored in warehouses. For this reason, more lenient requirements are imposed on insulation.

• Resistance to moisture and chemicals - the warehouse area can be periodically sanitized using water and chemicals, so the material should not be vulnerable to them
• Possibility of application to almost any surface - the warehouse can be built from metal, stone, concrete, wood or combinations thereof. The material must adhere perfectly to any substrate
• Provide maximum efficiency with minimum consumption useful volume of premises - if the insulation layer is too large, and for its fastening you will need additional frame, then its use will be inappropriate, since it will go to the minus of the useful internal volume of the warehouse
• Be affordable - a lot of insulation may be required - it all depends on the scale of the warehouse. Therefore, the price of the material should not only be acceptable, but also completely justified and economically feasible.

Vegetable storage

These are specialized warehouses or hangars designed specifically for storing fresh vegetables or fruits. Here special meaning has a temperature regime and humidity level. They are often built from stone or concrete, equipped with systems forced ventilation and refrigeration units. In this case, it is very important to properly insulate the vegetable storage facility in order to reduce energy consumption to ensure its operation. Since we are talking about food storage, one of the main requirements for insulation is environmental friendliness and chemical neutrality. Under no temperature conditions and influences should the thermal insulation material emit toxic substances. In addition, the range of its operating temperatures should be quite wide.

General requirements for insulation for warehouses, hangars and vegetable stores

In addition to those already listed above, there are also some General requirements To thermal insulation materials, regardless of where they will be used:

There are a number of requirements for thermal insulation materials, compliance with which when choosing them is simply mandatory.

• Fire safety - materials should not have a negative impact on the level of fire safety, and ideally they should protect load-bearing structures from the effects of fire in cases of local fires
• Durability – carrying out regular major repairs of a warehouse is impractical. Therefore, the material must be extremely durable

It is now absolutely clear that the market thermal insulation materials It is very difficult to find the golden mean that is being discussed. Of course, oh self-insulation a whole hangar is out of the question - this task is too large-scale, requiring professionalism and rich experience, relevant production resources. Therefore, let’s consider what companies can offer today, and what has already become a thing of the past.

Thermal insulation materials of a bygone century

This is not to say that they are not used anywhere today. These materials are still used to this day by contractors seeking maximum savings and benefit for themselves during the construction of private and apartment buildings, as well as for insulation of some industrial and commercial facilities.

Styrofoam

This material is familiar to everyone. Today it is still used for external insulation in some countries. However, its use is associated with a number of difficulties and dangers. TO negative points the following can be attributed:

Today, polystyrene foam is still used for exterior insulation in some countries. However, its use is associated with a number of difficulties and dangers.

• High degree of flammability - polystyrene foam burns like high-octane fuel. At the same time, it releases toxic volatile compounds into the air - pure poison. Extremely dangerous to human life and health
• He only likes flat surfaces - he is quite fragile. This is a sheet material that can only be used on flat walls. Lack of flexibility makes it impossible or extremely difficult to insulate structures of irregular shapes
• Installation is detrimental to the foundation and requires the use of anchors. You can't attach it everywhere. By violating the integrity of the foundation, specialists reduce the service life of the entire structure
• Short-lived - average service life is only 15-20 years

No matter how hard you try, you won’t be able to save money, and not everything can be insulated with it. And the presence of joints significantly reduces its effectiveness. Moreover, there is no need to talk about environmental cleanliness either. Requires careful protective finishing. So, we immediately cross him off our list of contenders.

Expert advice: When backfilling soil in 90% of cases, the foam, as well as the waterproofing coating, which is most often ordinary polyethylene, is damaged. Therefore, the rise in level groundwater leads to the wall getting wet, as well as to loss of insulation efficiency.

Mineral wool

Compared to foam plastic, more safe material, since at least it does not support combustion. However, when exposed to fire or even high temperatures, it releases volatile formaldehyde, which does not make it completely safe. Installation also poses a number of difficulties, since the material requires the use of additional fasteners. But this is not main drawback of this material:

Compared to polystyrene foam, mineral wool is a safer material, since it at least does not support combustion.

• Afraid of moisture - when wet, it loses up to 80% of its nominal effectiveness
• It is a heavy and dense sheet material - this indicates not only the impossibility of using it for insulating vaulted roofs of hangars, but also the presence of seams, which are the weak point of any insulation
• Durability is average - service life does not exceed 25 years

Even with a stretch, this material also cannot be called the best insulation. But many companies offer precisely these materials for insulating warehouses, hangars and vegetable stores. We strongly recommend that you avoid such disservices. After all, there is modern material, which is much more efficient. Why shouldn't you insulate with mineral wool? The answer can be found in the video:

Foamed polyurethane "Ecotermix" - maximum efficiency and economic feasibility

Ecotermix company offers the maximum effective solution problems with insulating warehouses, hangars and vegetable stores using polyurethane foam. This unique material, which is based on natural components obtained in the process of agricultural activities. Not only is the composition of polyurethane unique, thanks to which it has the highest performance properties, but also the method of its application itself. But first things first. Let's look at the key operational benefits foamed polyurethane:

The Ecotermix company offers the most effective solution to the problem of insulating warehouses, hangars and vegetable stores using polyurethane foam.

• Highest degree of efficiency – 90% polyurethane foam consists of microscopic air bubbles, which, as is known, has minimal thermal conductivity. Accordingly, the material itself most effectively allows you to maintain an optimal microclimate inside hangars, warehouses or vegetable stores
• Ease – the weight of the material does not exceed 11 kilograms per cubic meter. For comparison, the same volume of mineral wool will weigh from 60 to 100 kilograms. Therefore, foamed polyurethane from Ecotermix can also be used to insulate light vaulted roofs of hangars
• Chemical neutrality and resistance to chemical influences – the only thing that can somehow damage this insulation is industrial solvents of some brands. Household chemicals not dangerous for him. And the material itself is absolutely chemically neutral, that is, harmless to people and food
• Ecological cleanliness – this allows the material to be used for insulating warehouses and vegetable stores with food products without any worries
• Strength and elasticity – a special type of polyurea bonds that form the basis of the material, giving it strength and elasticity. Thanks to this, the material copes excellently with thermal deformations of the base and moderate mechanical stress.
• Polyurethane is not afraid of moisture – polyurea, which is based on the same components and elements, is used for waterproofing, which is unsurpassed today. Therefore, foamed polyurethane is also invulnerable to moisture, and its absorption coefficient is a maximum of 1.5% of the total volume
• The material is fire resistant – Ecotermix polyurethane foam not only does not burn, but is also able to withstand fire, protecting bearing structures from its harmful effects. This allows you to significantly increase the level of fire safety
• Durability – the service life of polyurethane foam is at least 50 years. There is no insulation that will last longer
• Protective effect – the material protects the base from corrosive influences and pests such as woodworms or mold

Now let’s get acquainted with the technology of applying this insulation. For this, Ecotermix specialists use a special unit that mixes two liquid polyurethane components in strict proportions and then feeds them into a sprayer under high pressure. That is, polyurethane is applied to the base using a spraying method similar to conventional surface painting. But the difference is that already a few seconds after spraying, a reaction begins between the components of polyurethane and air. It foams, becoming saturated with microscopic air bubbles, increasing in volume up to 70-100 times!

To spray polyurethane foam, Ecotermix specialists use a special unit that mixes two liquid polyurethane components in strict proportions and then feeds them into a sprayer under high pressure.

This application method allows you to cover surfaces of any shape, fill any niches, joints, even in the most inaccessible places in the structure. But that's not all. The insulation has the highest degree of adhesion, so it can be applied to any base: wood, metal, stone, concrete. In this case, the base does not require serious preliminary preparation. It just has to be clean. The advantages of this application method include:

• Completely sealed – the coating is seamless, which means it simply has no weak points
• Time saving – insulation of even large industrial facilities takes a minimum of time, which allows them to be put into operation faster
• Maintaining the integrity of the base – this allows you to maintain the nominal operational life of the structure, and sometimes even extend it

Today there are simply no analogues to polyurethane foam in terms of properties and installation method, and any alternative is much less effective. Therefore, polyurethane foam is successfully used for thermal insulation of real estate, namely: and other structures. It's wonderful, and equipment. Let's take a closer look at how hangars, warehouses and vegetable stores are insulated.

Insulation of hangars with foamed polyurethane

Often hangars are built on metal frames using thin sheet steel. Polyurethane is applied directly onto it, resulting in something like a sandwich panel. The insulation is applied in an even layer with inside, after which it can simply be covered protective layer polyurea, and be used in this form. If desired, it can be sheathed with any finishing material. Often, a layer of about 10 centimeters is enough to insulate a hangar. This allows you to maintain an optimal microclimate inside for maintaining equipment, transport, and food.

Polyurethane is applied directly onto it, resulting in something like a sandwich panel.

It is important that when polyurethane hardens, it produces an additional strengthening effect, increases the level of sound insulation, and dampens vibrations. This makes staying inside more comfortable and also extends the service life of the hangar. All supporting structures are enveloped in this material, which protects them from any external influences. Insulation of polyurethane foam occurs in a short time. We recommend watching a video where the hangar was insulated in 3 days:

Insulation of warehouses with foamed polyurethane

Warehouses built of stone or concrete can be insulated both inside and outside. External insulation is considered more effective, as it prevents the wall from freezing during the cold winter season. Polyurethane foam is applied directly to the wall itself, and then covered with a layer of plaster mixture and is painted. For achievement maximum efficiency You can carry out comprehensive insulation by covering the walls with an additional layer of foamed polyurethane from the inside.

Polyurethane foam is applied directly to the wall itself, and then covered with a layer of plaster mixture and painted.

For external insulation, polyurethane foam absorbs all the blows of the elements, coping with them perfectly. This way, the warehouse walls will last longer, since they will not be subject to temperature changes and other negative influences. Porous and loose surfaces are pre-coated with waterproofing (polyurea) and primer. Insulating a warehouse allows you to significantly reduce the cost of heating or air conditioning. There will be no dampness or mold, which is especially important when storing non-moisture resistant products.

IMPORTANT: PPU is non-flammable and environmentally friendly insulation, so you won’t have to worry about regulatory documents. The material is safe for people and does not have any effect on goods or raw materials stored in the warehouse. Therefore, this will be the best option for you.

Insulation of vegetable stores using polyurethane foam

Foamed polyurethane (FPU) is ideal for insulating vegetable stores. Its environmental friendliness and chemical neutrality allows you to preserve products in the form in which they were placed in storage. It is here, where refrigeration units or complex air conditioning systems are most often used to maintain an optimal microclimate, that foamed polyurethane is especially needed.

Foamed polyurethane (FPU) is ideal for insulating vegetable stores.

Energy costs can be halved, since the microclimate will be much easier to maintain. Both external and complex insulation of vegetable stores is acceptable. It is very important that polyurethane foam is excellent for thermal insulation of communications, such as ventilation ducts, For example. It perfectly fixes them, absorbing vibrations and making the system quieter.

When should work be carried out to insulate a warehouse, vegetable store or hangar?

Of course, insulation of such facilities must be carried out even before they are put into operation at the construction stage. However, the Ecotermix company provides insulation services for already used objects. With external insulation, there is no need to even suspend the activities of a warehouse, hangar or vegetable storage. Thermal imaging allows you to identify the weakest points of a building, which means focusing on them.

IMPORTANT: Optimal conditions for external insulation Foamed polyurethane will be used in calm, dry weather with air temperatures from +10 to +30 degrees Celsius. After complete hardening, which will take only a few hours, the operating temperature range of the material will be from -90 to +100 degrees Celsius. Internal insulation can be carried out at any time of the year, regardless of external conditions.

And we continue to answer questions from our readers who have encountered certain problems during the insulation process. Now we are considering issues related to the insulation of warehouses, hangars and vegetable stores.

Questions from our readers

Stepan M., Kaluga city : "Hello. Faced a serious problem, having lost most of the crops last year. Construction of the vegetable storage began two years ago. Total capacity – 1500 tons. We mainly store onions. Insulation was provided to maintain the required temperature levels. Our storage is semi-basement type. The upper level, above ground, was insulated from the outside with mineral wool, and the lower level was insulated from the outside with polystyrene foam. As a result, the entire lower level was covered from the inside with moisture - condensation - throughout the winter. As a result, the vegetable simply rotted in the storage throughout the winter, since the ventilation could not cope with such humidity. Now we can’t get rid of the fungus and mold that have covered all the corners. A new season is just around the corner, so we want to quickly solve the problem. What could be the result of this dampness? Maybe we chose too much thin foam? But on the advice of experts, we took best option. What should we do? Thank you"

Hello, Stepan. In some cases, the appearance of condensation on the walls after insulation can indeed be a sign of low efficiency of the material. But this is far from the only problem that may be causing your troubles. Firstly, when installing foam plastic, you probably used plastic anchors to ensure secure fastening. At the same time, you drilled the foundation. Often these holes become weak points during operation. If your region has a high groundwater level, then this condensation may be the result of a banal wall getting wet. In any case, there is only one way out - you need to dig again underground part storage facilities. It is necessary to remove the foam and insulate it with foamed polyurethane, followed by application waterproofing coating– polyurea. On the outside, such a coating can be plastered over a reinforcing mesh. After this, you can safely backfill and be confident in the effectiveness of the insulation. Additionally, we recommend insulating the top of the storage area with polyurethane foam from the inside. This will guarantee that the temperature will be even, even if the insulation with mineral wool was not carried out professionally.

Vitaly G., Petrozavodsk : "Greetings. Finally, I fulfilled my long-time dream - I purchased a small six-seater plane. I will use it for private purposes. A small hangar is currently under construction. I didn’t become more sophisticated - I leaned toward using a typical steel structure With metal casing. I want to make the hangar heated so that maintenance can be done right there at any time of the year. I also plan to keep a car and two tractors there, so there will be enough work with them both in the spring and in the fall. What is better to use for insulation? I've heard about some kind of Ecowool - what is it? They say it's expensive, but effective. What do your experts recommend? Thank you"

Hello, Vitaly. Great question! Indeed, today there is such insulation on the market as Ecowool. The new-fashioned prefix “Eco” often speaks of the environmental friendliness of the product, but not in this case. The manufacturer is guided only by the fact that Ecowool is based on cellulose. But to give it the properties it has, a number of chemical binders are used.

Expert advice: What is Ecowool? This is insulation that is applied by spraying, like foamed polyurethane. But in the case of Ecowool, the process takes much longer, and the most hard to reach places Most often it is not possible to cover evenly. Ecowool does not have high performance characteristics. It is afraid of moisture, reacts poorly to thermal deformations of the base, is not able to withstand fire, and often even supports it.

As you very correctly noted, ecowool is very expensive. And the worst thing is that it doesn’t justify its price. Foamed polyurethane “Ecotermix” fully pays for itself several times over a long service life, which exceeds 50 years. Do not forget that Ecowool will not be the most the best reason for many finishing materials. But you can cover frozen polyurethane foam with almost any finishing material. Obviously, the choice should be made in favor of polyurethane foam. Additionally, it will have an anti-corrosion effect, increase the level of sound insulation, the degree of fire safety and the strength of the entire structure. And, of course, this insulation will allow you to maintain an optimal microclimate inside your hangar at minimal cost.

Olga M., St. Petersburg : "Hello. We have such a problem. The warehouse premises are located in the same building as the production complex - one common wall, as well as parking for semi-trailers. The latter is not insulated in any way, so it is very cold in the warehouse. Partitions made of ordinary profiled steel sheet. Of course, it is impossible to talk about the efficiency of warehouse activities. It is simply impossible to be in a warehouse, since the temperature inside is almost the same as outside. What can we do in this situation to ensure normal work warehouse? We were offered mineral wool, but in those conditions it would be a waste of money. I also don’t want to erect additional partitions.”

Hello Olga. Indeed, mineral wool, like bulk insulation, will be completely useless in such a situation. We offer you Ecotermix foam polyurethane, which will ensure complete tightness and allow you to close all cracks and joints. This insulation is applied by spraying, after which it increases in volume almost 100 times. Thanks to this, all joints between individual sheets of corrugated sheets are completely sealed. The material is applied directly to the metal, adhering perfectly to it. If desired, you can carry out subsequent finishing with any materials.

Let's sum it up

For insulation of any warehouse, vegetable store or hangar, you will not find a better material than foamed polyurethane, which in all respects bypasses any alternative solutions. If you value money and time, and are also focused on achieving an impeccable result, then the specialists of the Ecotermix company are at your service. It's not only best rates, but also guarantees the quality of the result. And this is the key to successful business in any field.

Convince yourself of the environmental friendliness and reliability of polyurethane foam from Ecotermix by watching the video below:

Hangar is optimal choice for vegetable storage, factory production, workshops and warehousing. Despite the fact that the majority industrial premises has a fairly large area, it is not difficult to insulate them using sprayed polyurethane foam in a matter of days!

PPU is the fastest and easiest way to insulate a hangar

As you know, a hangar is a construction structure made using frame or frameless technology. The configuration of the hangar and its equipment directly depend on the operational tasks set by business owners or tenants.

Hangar insulation options

PPU is applied to the surface by spraying special foam under pressure

When choosing a material for insulation, it is necessary first of all to operate with such a significant parameter as the thermal conductivity of the selected material. If we turn to the technical parameters of insulation, then the thermal conductivity value for mineral wool is 0.06 W/mK with a working layer thickness of 30 mm.

For polystyrene foam, this ratio is as follows: 0.04 W/mK with a thickness of 20 mm, but the thermal conductivity of polyurethane foam is 0.03 W/mK with a thickness of 15 mm. These are the best characteristics for high-quality insulation. But thermal conductivity is not the only parameter that builders consider when making a decision.

The effect of condensation on insulation material

Most insulation materials are afraid of condensation. It is condensation that is the main problem of all owners of metal insulated hangars. Moisture formed as a result of temperature changes and accumulating on the metal ceiling of the room gradually destroys the performance characteristics of the insulation.

In order to extend the period beneficial use mineral wool and expanded polystyrene require effective wind and moisture protection, special vapor barrier membranes, modern system ventilation. This is especially true for the mineral version.

Otherwise, if the recommended operating conditions are not observed, mineral wool insulation becomes an unsafe source of bacteria and mold. But such additional measures significantly increase the period of completion of work on high-quality insulation of a storage facility or warehouse.

Advantages of polyurethane foam insulation

10 years warranty on work

Polyurethane foam solves many problems, since the technology of its application and specifications the material itself significantly reduces the installation time for insulation. Indeed, polyurethane foam is applied to the surface by spraying special foam under pressure.

Polyurethane foam creates a unique, smooth coating without cracks or crevices. This material does not require complex and expensive surface preparation. It is unique in its essence. The layer thickness can be precisely controlled down to the millimeter. PU foam is not afraid of irregularities, bends and complex designs, the foam reliably and durablely seals the entire surface intended for insulation.

The thickness of the foam layer is calculated in advance, taking into account the climatic parameters of the area where the shopping or industrial complex is located. The impressive service life of the insulation layer made from polyurethane foam is also impressive.

Service life of hangar insulation

The actual service life of polyurethane foam without loss of consumer properties and performance characteristics exceeds 30 years; for a more favorable climate, this value can reach 50 years. No other modern insulation can compare with such parameters.

For example, a vapor barrier film works effectively only for 10 years, and extruded polystyrene foam only for 20 years; even such values ​​are unattainable for mineral wool. It reliably insulates for no more than 5 years. But replacing the insulation for a hangar every 5 years is a significant expense. Therefore, experts have recognized that it is much more economical to thermally insulate a hangar with polyurethane foam for 30 or even 50 years.

The influence of insulation on structures

It’s possible to insulate a huge hangar in 3 days!

An interesting fact is that polyurethane foam insulation has the least impact on the main structures. This foam, when hardened, is very light in weight. She is the most lightweight material for insulation known at the moment. Since hangars are lightweight structures, insulation, which leads to increased load on the surface, is highly undesirable, as it can lead to the destruction of the entire structure.

Such a threat is impossible if the insulation is polyurethane foam. In addition to being very lightweight, this material is an excellent anti-corrosion material. The most effective, taking into account all the above advantages, is Ecotermix polyurethane foam. Competitive advantages Ecotermix polyurethane foam for insulating surfaces is obvious.

Main characteristics of Ecotermix polyurethane foam

• Ecothermix does not require special devices for installation, it is applied by spraying without creating cracks or unevenness
• Ecotermix polyurethane foam is ready for application on any surface, no complex and expensive preparation for work is required, the geometric shape of the building is unimportant
• Polyurethane foam is not afraid of condensation, it adheres so tightly to the surface and has no pores that it is not affected by moisture and does not become a platform for the spread of rot and mold
• Ecotermix insulation has the best characteristics in terms of speed of work completion; insulate a metal hangar big size possible in 3 days
• Ecotermix material has the most interesting parameters in terms of efficiency and durability of insulation; it is the most best indicator thermal conductivity and the most impressive service life, Ecotermix is ​​effective without loss of performance characteristics for 50 years
• Ecotermix polyurethane foam performs a number of related functions, it is an excellent waterproofing and anti-corrosion treatment, while it is resistant to the aggressive effects of acids and alkalis
• Despite its lightness, polyurethane foam is very durable, it can withstand significant work loads without cracking or deforming, it is inaccessible to rodents

Economic feasibility of choosing Ecotermix

PPU hardens in a matter of minutes

Another pleasant fact is that the use polyurethane foam material for insulating rooms allows you to save money. Indeed, a service life of several decades without loss of performance makes the cost of Ecotermix polyurethane foam the most attractive.

As you know, the outer walls of a hangar or car wash (or indeed any other structure) are not airtight, which causes significant heat loss. To solve this problem, owners of buildings often resort to insulating them, sometimes even doing it.

Thermal insulation of walls is one of the most important tasks when arranging a hangar or car wash, because it can significantly reduce the cost of heating a room. If earlier the insulation of a structure was carried out with ordinary mineral wool, today the system of spraying polyurethane foam has become widespread.

For correct application You should familiarize yourself with all the advantages of this method and carry out high-quality thermal insulation work.

1 Features of the technique

Insulating a hangar with polyurethane foam allows you to simultaneously solve several problems:

• reduce heat loss from the structure;
• improve waterproofing of the structure;
• insulate basements.

The method of insulation using polyurethane foam (polyurethane foam, for example) is increasingly used today to insulate the walls of a car wash or hangar. The technology has gained high popularity due to the exceptional qualities of the material.

Polyurethane foam is a type of gas-filled plastic. Polyurethane foam is delivered to the site in the form of two separate components - isocyanate and polyol.

A powerful air atomization apparatus mixes liquids in a special way and delivers a fine aerosol at the output. Polyurethane foam penetrates into the smallest cracks and hard-to-reach areas, after which it quickly hardens.

Ultimately, polyurethane foam is a porous polymer rock that consists of 80-90% air.

1.1 Advantages of the polyurethane foam spraying method

Thermal insulation of walls using the polyurethane foam spraying method can be used for any hangar geometric shape. The insulation system, at the request of the customer, is implemented from the inside or outside of the structure.

The advantages of using PPU material are as follows:

• exceptional quality of thermal insulation;
• high wear resistance;
• resistance of polyurethane foam to environmental factors;
• quick installation as in the case of ;
• absence of seams on the surface of the walls;
• strengthening the hangar structure;
• fire resistance;
• low costs for carrying out the work.

Insulating walls using polyurethane foam, regardless of whether it is carried out from the inside or outside of the hangar, is a very effective way to avoid heat loss. The material has a low thermal conductivity coefficient (less than 0.03 W/mK), which allows for exceptional quality of thermal insulation.

An important advantage of polyurethane foam is the ability to apply a layer of material over the entire area of ​​the structure, including beams and other elements of the hangar. Thus, the treated surface does not contain any seams. This not only provides a pleasant aesthetic appearance to the walls, but also guarantees reliable insulation designs.

Polyurethane foam, regardless of whether it is used inside or outside the hangar, retains its insulating properties for over 30 years. In addition, the foam spraying method is economical and does not require large investments.

The work is carried out without the use of additional fasteners, and the structure itself does not require laying a hydro-, steam- and wind-insulating layer. Due to the fact that the hangar does not need preliminary preparation, the time required for installing the PPU or from inside the hangar is significantly reduced.

The material is highly fire resistant and well resistant to chemicals and environmental conditions, including low temperatures, moisture, and wind loads. Polyurethane foam will additionally strengthen the hangar structure, increasing its reliability and endurance.

2 Insulation technology using polyurethane foam

The technology of insulation using polyurethane foam begins with preliminary drying of the surfaces being treated, removing dust from the walls and degreasing them. These negative conditions worsen the adhesion of the composition and slow down the passage of chemical reactions.

Metal structural elements are cleaned of rust if necessary. Before insulation, specialists must carry out testing: a control sample of the composition is applied to the surface and the process of hardening of the mass is monitored.

If the result fully corresponds to what was expected, you can begin the main work. Spraying of polyurethane foam with installation is carried out in several layers, the first having a thickness of 10-15 mm. The second and third are applied a few minutes later.

Insulation must be carried out during a period when the ambient temperature exceeds 10°C, otherwise the chemical reaction process may be disrupted. Rain and high air humidity have a negative effect on polyurethane foam spraying.

By adhering to a number of simple rules and following technology, you can qualitatively insulate the structure, protect it from wind, corrosion, rodents, and also reduce the cost of maintaining the hangar, saving on heating.

2.1 The process of insulating a hangar using polyurethane foam (video)

A high-quality insulated hangar for small aircraft - not only to the maximum appropriate place for parking a private plane, but also a source of pride, especially if its construction and further arrangement were carried out by you yourself. Such premises are suitable for parking and maintenance not only aircraft, but also other large equipment. Next, we will look at insulating a hangar with our own hands, key principles choice of material and step-by-step insulation technique.

How to properly insulate a hangar?

The construction of a hangar must be accompanied by compliance with all necessary conditions for storing aircraft and mandatory insulation walls and ceilings is one of them, since equipment is sensitive to humidity and sudden changes in temperature.

Optimal storage conditions for aircraft.

Air vehicles require proper operation, maintenance and storage, especially if we are talking about a private jet or helicopter. Having decided to buy such equipment, do not rush to show off your expensive acquisition to everyone around you, since it is paramount to carefully consider and provide the necessary conditions for its storage and regular maintenance.
Design features of small aircraft hangars:

1. Aircraft should be stored in a well-ventilated, wide-span hangar. Internal supports may be missing.
2. Smaller structures are allowed for storing helicopters.

In both cases, the room must be insulated, since such equipment should not be exposed to the negative effects of weather factors, otherwise breakdowns are inevitable, but you cannot simply stop an emergency aircraft for regular repair work. In what ways can these conditions be achieved and what needs to be done to achieve this?

Methods for insulating a hangar

A technology that involves both external and internal insulation of hangar walls is the most effective option, since it will be warm outside and inside, and the structure itself will not be subject to corrosion. This is especially true in cases where it is planned to insulate a metal hangar. Heating costs will be significantly reduced, but due to the cost of this method, it is customary to choose only one of two options:

1. External insulation involves installing insulation with outside and taking into account construction standards, this method is the most correct. Besides, effective area the hangar itself remains the same.
2. The choice of internal insulation is fraught with the formation of condensation between cold wall and a warm layer of insulation, there is a high risk of walls freezing. If foam plastic is also used in this case, moisture will form at the joint and the structure will soon collapse. When insulating from the inside, harmful fumes are released into the room, especially if you give preference to mineral wool, glass wool or polystyrene foam. To avoid these troubles, take the choice of the manufacturer of the thermal insulation material and adherence to the technological process with due seriousness. Cheap insulation always carries the risk of being poisoned by hydrogen cyanide, hydrogen bromide, styrene or phosgene.

Brands and properties of insulation

The choice of material for thermal insulation of a small aircraft hangar directly affects material costs, since the dimensions of the premises in question are more impressive compared to a conventional garage or residential building. The configuration of the structure also plays a role important role, since in certain cases there are obstacles to the use of sheet materials.

Principles for choosing insulation

1. Price is a choice factor that guides many. The first thing you should do is calculate the budget and then move on to other indicators.
2. Be sure to take technology into account, because when internal insulation safety and thickness of the heat insulator are decisive factors, while exterior work can be done using any raw material.
3. The hangar room is different high humidity, so it is worth paying attention to corrosion prevention and moisture absorption properties.
4. Not every aircraft storage structure is designed for high loads, so the weight of the insulation should be small.
5. Consider the possibility of repair work, calculate how expensive it will be and try to choose the most durable insulation.
6. The effectiveness of a material is determined by comparing thermal conductivity values, e.g. cinder block wall a meter thick corresponds to a five-centimeter layer of polystyrene foam, which has an indicator of 0.037 W/mK.
7. Don't forget to take into account the building material. Metal structures should be additionally covered with plywood sheets, under which there will be a layer of thermal insulation. Liquid materials They are perfect for such purposes: apply a couple of layers of thermal insulation, taking into account a daily technological break to ensure intermediate drying. Brick hangars require the creation of partitions with insulation material, which can be polystyrene foam. When choosing a similar material, ensure effective protection against rodents by covering the surface with clapboard.

Types of insulation

Almost all modern thermal insulation materials have a lot of advantages, but each of them is not suitable for every type of structure. Let's look at their differences and the relevance of the choice in specific cases.

Main stages of work

The insulation process begins from the ceiling of the hangar, moves to the walls and ends with the gate. Next, detailed technology for each section of the structure will be considered.

Hangar ceiling insulation

Glass wool is most often preferred when it is necessary to insulate the roof of a hangar. Glass wool with a dense structure in the form of rolls is suitable for pitched roof. The process of installing a heat insulator involves placing the material between the rafters sideways if the beams are thick enough to provide ventilation between the water barrier and the insulation. In other cases, a 10 cm thick heat insulator is mounted on top of the rafters. Next, you should cover the structure with a vapor barrier and fill the bars for further fixation. facing materials. This could be fiberglass board, clapboard or drywall.

Insulation of hangar walls

As mentioned earlier, installation of thermal insulation materials can be carried out inside or outside the hangar. Taking this fact into account, we will consider detailed technologies insulation.

A central heating system for hangars is expensive, since carrying out such work in the area where the hangars are located requires high costs. For this reason, this method is considered not economically feasible. The only solution to this problem is a set of measures that will help maintain desired temperature indoors all year round.

The internal thermal insulation of the hangar with polyurethane foam allows you to optimize heat loss in winter.

Why is it worth insulating a hangar with polyurethane foam?

To answer this question, you need to understand the types of thermal insulation for this type of room. There are 2 main methods of insulating a hangar:

• tiled building materials;
• gradual spraying of polyurethane foam.

In the first method, as a rule, polystyrene foam, mineral wool and basalt fiber. Insulation with these materials can significantly reduce the thermal conductivity of the treated floor, but it will become more susceptible to moisture that appears due to the formation of condensation. The method of thermal insulation with tile insulation involves arranging a sheathing into which a slab of the selected building material will be inserted.

Before placing the sheathing from metal mesh it is necessary to install a material that protects the structure from wind and moisture, and stretch a vapor barrier polyethylene over it. It is clear that this method will require spending a considerable amount Money, not to mention the labor-intensive process of thermal insulation. In addition, there is a possibility of rapid wear of the vapor barrier film in winter period, since light-weight metal structures tend to undergo slight deformations due to mobility under wind pressure.

The method of spraying polyurethane foam is very different from the technology of thermal insulation using tiled building materials. First of all, it is worth noting that polyurethane foam (PPU) has a high level of adhesion. This allows you to process the surface without the need to create lathing. Insulation of hangars is carried out by seamless spraying without the presence of cold bridges.

This material does not require separate protection from wind pressure and condensation. It is sprayed either indoors or outside. Using the second method of insulation, it is enough to cover a layer of thermal insulation special mixture, protecting it from ultraviolet exposure to sunlight.

Mineral wool exerts significant pressure on the metal structure, and polyurethane foam insulation for hangars, on the contrary, without adding excess mass, strengthens the structure of the walls. This is especially useful when insulating frameless hangars.

Another advantage of polyurethane foam insulation is aesthetics. Once the thermal insulation is complete, you can leave the hangar as is. Of course, if desired, you can apply paint of the desired color on top of this layer.

Features of applying polyurethane foam

This type of thermal insulation belongs to the group of gas-filled plastics, which are popularly called foam plastic. Polyurethane foam is similar to resole, polystyrene foam and urea types of plastic products.

Two types of liquid are transported to the hangar location:

• isocyanate;
• polyol

Connection diagram of the components of the installation for spraying polyurethane foam under pressure.

Using air atomization technology, both liquids are mixed inside the nozzle under the influence of air pressure. Thanks to this method, the smallest particles create a kind of aerosol, which is applied in an even layer to the surface of the metal structure, reaching even the most inaccessible areas. All kinds of cracks, holes and cracks are carefully sealed, forming an airtight layer.

During the process of application to the hangar, a chemical reaction occurs in the polyurethane foam mixture - the spray foams and begins to harden. After 2 hours, the layer of applied mixture hardens by 90%, and after 24 hours this figure is 100%.

In the form in which polyurethane foam is applied to the surface, the mixture contains many pores, since its content is 80-90% air. It is thanks to air that the polymer properties of the material acquire thermal insulation characteristics high strength.

Polyurethane foam exhibits good resistance to acid, alkali, oil, fuel and oil, which exists in any hangar. For this reason, it is ideal for rooms of this type. Thanks to high level adhesion polyurethane foam can be applied to following types surfaces:

• metal;
• reinforced concrete;
• arched openings;
• ceiling covering;
• coverings with recesses and protrusions.

Considering that polyurethane foam exhibits high stability to vapors and moisture, there is no need for additional protection surfaces with vapor and waterproofing materials.

Also, PU foam does not need to be protected from rodents and mice, since animals do not touch the surface treated with such material. In addition, mold or mildew does not form on it. Polyurethane foam is not exposed to atmospheric and temperature effects; it can only be destroyed by mechanical damage.
