To get rid of the so-called "cold bridges" in warehouses, it will be necessary not only to close up all the cracks. Given the fact that such rooms have a large area, it is necessary to insulate all the walls well. It is necessary to get rid of such a phenomenon as a leak of warm air.

What is the difficulty?

Today, during the construction of new warehouses, they are immediately used. But what if this is an old room and it is necessary to place goods in it, which in winter should be stored at positive temperatures? In this case, you need to think about performing repair and finishing work using heaters. And first of all, you need to insulate the walls. But no matter what insulation is used, it will be of little use if the issue with the gate is not resolved.

The thing is that the gates of many warehouses open almost daily to carry out the process of unloading and loading products from trucks. Therefore, two questions need to be addressed at once:
- the gates must be opened for the shortest possible time;
- the process of loading and unloading goods must be minimized in time.
In most cases, hangars and warehouses have a large area. In addition, they are built using a special frame technology. In the process of their construction, metal structures and steel sections are used, which are completely incapable of retaining heat. Therefore, they must first be insulated.

Not every warehouse can suspend its activities so that finishing work is done to insulate the walls from the inside. Therefore, such work often has to be done at night. When insulating the walls of a warehouse, it is necessary to take into account another very important nuance: many works will have to be done at height, so additional equipment will be required in the form of a tour - a mobile tower or convenient stairs.

The main types of warehouse insulation are most often used such materials:
- mineral wool;
- sprayed polyurethane foam;
- sandwich panels;
- Styrofoam.
Each of these heaters has its own advantages as well as disadvantages. Therefore, they should be considered separately.

1. Mineral wool: is a classic way to insulate warehouses. This method of insulation is cheap. In addition, mineral wool fireproof, which is very important for such premises. But she also has drawbacks. For example, it is able to absorb moisture. In addition, it has a decent weight for a heater, which can be dangerous for thin walls made of galvanized steel.

2. Sprayed polyurethane foam has been very popular lately. He is able to close up all the cracks, is not afraid of fire, has low thermal conductivity. It is very easy and quick to apply on the walls. But its disadvantage is the high cost. Yes, and the warehouse must be stopped for the duration of such insulation.

3. Sandwich panels are very beautiful and strong enough. Their advantage lies in the fact that they do not require further finishing. But from the shortcomings of such a heater, one can single out the laboriousness of the work and their decent weight. And this means that the load not only on the walls, but also on the foundation will increase significantly.

4. Styrofoam is the cheapest insulation. When the walls are insulated, the warehouse can not even be stopped. It also differs in that it is very light. But it also has disadvantages: rodents love it and it is a highly combustible material.

Therefore, how to insulate your warehouse is up to its owner. In this case, it is necessary to take into account its size and what material it is built from.

Thermal insulation of pipes in our country is a practically necessary procedure. The fact is that in winter the air temperature drops quite low. Severe frost can simply "break" the pipe. Probably, it is not necessary to explain that such a nuisance will bring many problems.

Thermal insulation for pipes is the best way to protect the pipeline from rupture. Of course, it is better to do it before any problems arise. What to do if the pipes are already frozen? Either defrost them, or replace them, and after that insulate them.

WHY IS PPU THERMAL INSULATION VERY POPULAR?

The most popular material for insulation is polyurethane foam.

Why is he in such demand? The reason for this is its characteristics.

1. Sealed. It does not allow water to pass to the pipes and thereby protects them from icing;

2. Excellent heat retention;

3. Durable. Insulation made from this material can last up to several decades;

4. Easy to install. It is possible to make insulation of PPU pipes within one day;

5. Inexpensive. Unlike many other materials, foam plastic has an affordable price.

Insulation of containers and tanks with polyurethane foam

The metal container is used not only as a container for transportation. Retail outlets, small warehouses, garages, water storage tanks - and this is by no means an exhaustive list of possible applications. Such a wide scope was provided by the low price, ease of installation, the ability to move to the desired point. The only disadvantage of containers is considered to be practically zero thermal insulation of such a design, and the use of most traditional insulation leads to a significant decrease in the internal volume of the container. This problem can be solved by spraying polyurethane foam, a new generation two-component material that provides thermal insulation with a minimum thickness of insulation.

Insulation of containers with POLYURETHANE FOAM

Thermal insulation of containers with polyurethane foam is a technically simple process, but it requires the use of special expensive equipment. In this regard, the price of spraying is somewhat higher than the cost of installing plate insulation, the economic effect of the technology is based on improved performance of the material.

• Installation does not require the use of additional fasteners. PPU is applied directly to the metal surface of the container, making it possible to abandon the traditional frame.
• The polyurethane foam insulation system does not require the use of hydro and vapor barrier, which greatly simplifies installation, increases its speed and reduces the cost of purchasing materials.
• PPU protects the metal container from moisture, thereby reducing the risk of corrosion foci, which allows to increase the life of the structure.
• We recommend installing polyurethane foam insulation from the inside, the minimum layer thickness will not reduce the usable volume of the structure, and simple painting will protect the polyurethane foam from sunlight.
• Polyurethane foam insulation compares favorably with its environmental safety, which is why its use is recommended for grocery outlets (unlike materials based on fiberglass and mineral wool).

Before installing the thermal insulation, the surface of the container must be cleaned of existing pockets of corrosion, it is also desirable to prime the cleaned places with special compounds. No other surface preparation is required.
The polyurethane foam mixture supplied under pressure penetrates into all available cracks and recesses, due to which a continuous coating is formed on the inner surface of the container, characterized by minimal heat loss. The spraying speed is quite high, our specialists process an object of average size in just one day, and work can be performed at any time of the year. In just a few hours, polyurethane foam reaches its design hardness and strength, and the container can be used for its intended purpose already on the day of installation of thermal insulation.

INSULATION OF TANKS WITH POLYURETHANE FOAM

Installation of insulation on tanks is difficult due to its cylindrical shape. For fastening traditional plate or roll materials, it requires the construction of fairly complex frame structures. That is why the most rational is the use of PPU for the implementation of such work. In addition, it should be noted that tanks insulated with polyurethane foam can be buried in the ground without additional waterproofing treatment. The material has a low moisture absorption coefficient, so PPU will provide reliable protection against the effects of soil water and other aggressive liquids.
Processing the tank with polyurethane foam allows you to organize the storage of various liquids prone to freezing, even in harsh climatic conditions. Thermal insulation of this class is also used in the installation of fire tanks to provide water supplies for fire extinguishing needs.

Our company performs thermal insulation of containers for various purposes and tanks throughout Moscow and the Moscow region. PPU spraying is carried out within the minimum period agreed with the customer, while the prices for our services are considered the most optimal in the region.

Insulation of vegetable stores with polyurethane foam

A big city needs a lot of food. That is why the construction and operation of premises for the storage of grain, fruits, vegetables is a fairly profitable business. The most rational vegetable storage is considered to be a prefabricated building with polyurethane foam insulation. The structure is mounted quickly, has a significant usable volume, and PPU spraying, which has good thermal characteristics, will help to ensure the temperature regime necessary for storing various products.

Types of vegetable stores with PPU insulation

Representatives of the agro-industrial complex appreciated all the advantages of thermal insulation based on polyurethane foam. Thanks to the appearance of such a heater, it became possible to construct reliable vegetable stores from almost any building. To date, the following types of such facilities are successfully operated in the Moscow region:

• Vegetable storage facilities based on prefabricated metal hangars and large containers.
• Converted brick and wooden buildings with double or single foam insulation.
• Basement and basement floors of industrial buildings, which, with minimal reconstruction, serve as efficient and inexpensive vegetable stores.

6 reasons to choose polyurethane foam insulation

To date, PPU is gradually replacing other existing heaters from the construction market. Experts explain the large amount of polyurethane foam used in the construction of vegetable stores for the following reasons:

1. The ability to perform insulation of buildings from various materials. Polyurethane foam adheres perfectly to metal, wood, concrete and brick surfaces. At the same time, PPU spraying does not require expensive preparatory work and the installation of supporting frames. Due to this, the cost of building or reconstructing a vegetable store is significantly reduced.
2. The use of high-performance foam application equipment can significantly reduce the installation time of thermal insulation. A professional installer is able to process up to 350-400 m2 of vegetable storage area per shift.
3. PPU thermal insulation has minimal moisture absorption and vapor permeability, thanks to which it is possible to create a microclimate that is optimal for storing various products, while there is no need for additional installation of insulating coatings.
4. Vegetable storage, which is insulated with polyurethane foam, ensures the safety of products both at negative and at high positive ambient temperatures. Separate rooms of the building can be converted into efficient freezers.
5. Insulation based on polyurethane foam has a significant durability, while providing protection from sunlight (which can be achieved by simply painting the insulation), the operational life of thermal insulation reaches 30-50 years.
6. Polyurethane foam is distinguished by absolute environmental and fire safety, which is why it is recommended for use in the construction of vegetable stores. The quality of stored products is not affected even by direct contact with PPU.

THERMAL INSULATION OF REFRIGERATION CHAMBERS WITH POLYURETHANE FOAM

Refrigeration units (industrial cold stores) must provide a sufficiently low air temperature, which creates optimal conditions for the storage and transportation of food, medicines, and some types of industrial products. If the thermal insulation of a domestic refrigerator does not cause difficulties, and can be performed using almost any heater, then when installing industrial-grade equipment, it is polyurethane foam that is most often used.

Reasons for choosing PPU for the installation of refrigerating chambers

The choice of polyurethane foam as the main material used for thermal insulation of mobile refrigerators and large-capacity refrigeration units is due to its physical properties and performance characteristics.

• The low specific gravity of the PPU-based insulation makes it possible to mount refrigeration units on the basis of ordinary freight transport; such thermal insulation does not create an additional load on the car chassis.
• Excellent adhesion of polyurethane foam allows it to be applied to almost any original surface. At the same time, the resulting coating is highly resistant to vibration loads that arise as a result of the operation of the installation that ensures the circulation of the refrigerant.
• Insulation with the use of polyurethane foam can be carried out both at the factory and at the place of direct installation of the refrigeration chamber. Thanks to this, the thermal insulation of industrial installations in logistics and shopping centers is carried out by spraying polyurethane foam. The small dimensions of the installation allow you to work both outside and inside the industrial refrigerator.
• Two-component polyurethane foam can be applied in several layers without breaking the solidity of the coating. This allows you to obtain thermal insulation of the required thickness (determined by the calculation of thermal characteristics and the required mode of operation of the refrigerator). In this case, spraying is carried out in a seamless way, which significantly reduces the heat loss of the installation.
• The minimum moisture absorption and vapor permeability of polyurethane foam allows you to create the most optimal microclimate for storing various products in the refrigerator. This significantly reduces the likelihood of condensation on the surfaces of the installation.

The possibility of applying polyurethane foam in a mechanized way and the minimum thickness of the required coating can reduce the cost of manufacturing refrigeration equipment. Due to this, the price of a refrigerating chamber with PPU thermal insulation compares favorably with other similar devices of this class.

Advantages of a PU foam refrigerator

First of all, it should be noted that polyurethane foam is absolutely harmless to the human body, in addition, the design of the refrigerator does not imply direct contact of the material with the products placed inside the unit. The use of polyurethane foam provides a number of operational advantages compared to other heaters.

• Thermal insulation made of polyurethane foam is not of interest to rodents, which ensures reliable safety of the structure.
• The thermal performance of the installation does not deteriorate over time. Unlike rolled mineral wool or slabs, PPU does not slip from vertical surfaces. The average life of a refrigerator insulated with polyurethane foam exceeds 50 years, while the payback period of the installation when loaded above average is from 2 to 5 years, depending on the working volume.
• To improve the energy efficiency of equipment, double spraying of polyurethane foam (external and internal) is practiced. This technique allows you to provide the necessary thermal performance with a minimum decrease in the working volume of the chamber.
• Insulation with polyurethane foam makes it possible to convert almost any room into a refrigeration unit at minimal cost. At the same time, the main share of the costs will be for the purchase of a refrigeration machine (compressor), the cost of applying PPU (even taking into account the price of the material) is significantly lower.

Our company carries out thermal insulation of any refrigeration units, including handicrafts, with polyurethane foam. We guarantee an affordable cost and an increase in the efficiency of refrigeration equipment after insulation work has been completed.

It is very difficult to heat a warehouse, especially a large one, even if you do not spare money for heating and install a couple of heat guns. Without insulation work, all these attempts will turn into a bunch of wasted money. In order for the staff inside the building to feel comfortable even in the cold season, the warehouse needs to be insulated. You can also find out in a separate article.

Since the insulation does not let in not only cold, but also heat, it will be quite cool inside in summer.

How to insulate a warehouse

Warehouses are insulated, like the rest. The only difference is that the insulation should be as efficient as possible and fit without cold bridges. Remember that through cracks and defects in the insulating layer, money escapes that can be spent on more necessary purposes. Therefore, the choice of materials and technologies must be approached as thoughtfully as possible.

Unfortunately, completely unsuitable materials are often offered for the insulation of warehouses. Therefore, before ordering a service, you need to understand all the options offered. What you definitely should not agree to:

• Various types of mineral wool. Many firms indicate as a plus that these materials have been used for a very long time. Consider whether you need outdated technology. The thermal conductivity of 0.040 W / (m * K) was previously considered excellent, and for this it was necessary to put up with the disadvantages of mineral wool - increased moisture absorption and installation complexity. When used, the facts were even ignored that one type of mineral wool - the so-called glass wool - causes damage to the respiratory tract of the skin and eyes, and the rest of the options contain harmful phenol. Especially dangerous is cheap mineral wool, which smells unpleasantly of phenol and formaldehyde. It is impossible to insulate a warehouse with it - it will be uncomfortable for the staff to be there, and the stored property will acquire an unpleasant smell of paint and a hospital. Nowadays, when there are more effective, simple and safe materials, it is not worth insulating with mineral wool. Moreover, its active promotion is associated only with the low price of the material and the possibility of obtaining additional profit;

• - Another material often offered for warming warehouses. The panels are two layers of plastic, between which a heater is laid. Sandwich panels are harmless to health and do not emit odors. However, the material has a serious drawback - the complexity of laying, caused by its weak plasticity. Sandwich panels are quite rigid, so it will not be possible to bend them. You have to cut the insulation into small fragments that are interconnected. This leads to the formation of cold bridges at the joints, through which cool air enters the storage room. Another disadvantage of sandwich panels is their high weight, which gives a high load on the foundation and walls. In addition, the sandwich panels are on fire. Therefore, if a short circuit in the wiring occurs in the warehouse, the building will flare up with the release of acrid black smoke;

• - Another super-budget insulation, which is "promoted" by many companies. Even children know that polystyrene burns, and the fire service is aware of the fact that it releases toxic substances when burned, which will fine the owners of the warehouse. Another disadvantage of polystyrene is its attractiveness to rodents. Mice and rats easily gnaw soft material and carry it into holes, and sometimes settle in the thickness of the plastic. Such insulation threatens with a constant mouse smell in the warehouse and damage to things that rodents will spoil along with the foam;

• - a good material with a high energy saving rate, but, unfortunately, very expensive. In addition, it requires the construction of various crates for laying basalt mats and slabs. Such insulation is more suitable for an apartment, house or office, but not for a warehouse.

What material is suitable for warehouse insulation

An excellent option is insulation by spraying polyurethane foam outside or inside the walls. External insulation is much more preferable, because it allows you to keep the warehouse running. In this case, the dew point - the area inside the wall where water vapor turns into water - does not enter the room. It falls on the thickness of the insulation, where water simply cannot condense. Therefore, with this type of insulation, the walls do not “cry” and mold and fungus do not grow on them.

The disadvantages of external insulation are the impossibility of carrying out in the cold season, with strong wind and high humidity.

If the warehouse urgently needs to be insulated in the middle of winter or it is very rainy in your area, it is better to prefer internal insulation. True, in this case, you will have to unload the entire warehouse, take out all the available valuables and stop work until the insulation and finishing are completed. But, fortunately, polyurethane is quickly applied and dries in a short time. Finishing can be carried out the next day after spraying. Therefore, the warehouse will not remain idle for a long time.

How is the insulation of the warehouse with polyurethane foam

Polyurethane foam (PPU) is a porous insulation formed by spraying from two components. Between the polyol and the isocyanate of which it consists, a reaction occurs, accompanied by the formation of a polymer insulation and the release of a large amount of gas. As a result, during spraying, a porous mass is formed, which increases in volume up to 10 times.

When expanding, polyurethane foam fills cracks, irregularities and voids, forming an even layer without joints and seams. Cold bridges do not form in it either.

Don't be put off by the use of a toxic, flammable isocyanate to produce PPU. The polyurethane foam resulting from such a reaction is completely harmless and neutral, and the air bubbles formed during spraying are filled with ordinary carbon dioxide, so they also do not contain any poison. There will be no permanent unpleasant smell and harmful fumes in the warehouse. The only thing that will have to be done is to ventilate the warehouse after the work is completed.

From above, the insulation is covered with a layer of material that isolates it from ultraviolet rays that decompose polyurethane foam. If desired, PPU can be covered with siding or special finishing plates.

Polyurethane foam has one of the lowest thermal conductivity values ​​- 0.020 W / (m * K), which is two times lower than that of mineral wool, polystyrene foam and basalt wool. Therefore, the material can be applied in a layer two times thinner than other heaters. This allows you to practically not reduce the area of ​​\u200b\u200bthe room and its height. A small layer thickness is also obtained due to the lack of crates necessary for insulation with roll and plate materials.

This material can also be used to insulate the floor of the warehouse. This technique is much more effective than filling expanded clay between the lags and laying damp cotton wool insulation. PPU is quite durable, therefore, during operation it does not break and does not become covered with cracks.

Together with insulation, floor waterproofing is often done, you can read about this in another article,.

For the development of industrial production, wholesale trade, and logistics business, it always requires a decent amount of warehouse space. In addition, warehouses-shops and Internet trading platforms that do not have separate areas for the sale of goods are becoming more widespread.

What is the difficulty

Of course, it is not difficult to build a small warehouse building from materials that already have heat-saving properties. But if we are talking about areas and volumes for organizing the storage of products, raw materials or goods, in the hundreds and thousands of square and cubic meters, then traditional construction methods will not be economically justified.

Hangars and warehouses of large areas are most often built using frame technology or using prefabricated structures. An example is the well-known arched metal structures assembled from wave-shaped steel sections.

The steel of the sections does not retain heat at all in winter and does not protect the internal volume from heating in the sun in summer. There are also warehouse structures made of concrete slabs, which also need thermal insulation. What methods and materials are used to improve hangars and other large premises?

Methods for insulating structures made of metal and concrete

Among the variety of ways to preserve heat in a warehouse, several basic and acceptable in terms of efficiency deserve attention.

Method 1: Create an Inner Path

The method of insulation by building an internal contour consists in the construction of a light, insulated, non-bearing frame structure inside the hangar.

Installation can be carried out using various technologies - using wooden rack or metal profile frames with the installation of foam or slab insulation in them and then facing with panels.

Significant disadvantages of the method are the reduction of the useful area of ​​the warehouse and the high cost of construction.

Method 2: insulation with basalt and glass wool slabs

Warming with slab, basalt or glass wool material as a method is effective in terms of heat conservation, but inconvenient to implement. In fact, this is the same option as with the internal contour, but the frame is mounted directly on the walls of the warehouse.

This additionally loads the hangar sections and may affect its stability. In addition, the fastening of rails or profiles to the steel of the walls may present a certain difficulty. Another disadvantage of this method is the moisture that inevitably accumulates in the thickness of the insulation and does not go outside.

Method 3: foam as a heater

Insulation with polyurethane foam has become popular. This material exists in two forms - in the form of plates and in the form of a liquid mixture, which, after application, foams itself. Plates are used to insulate the outer surfaces of wooden or concrete walls, and the walls inside the premises are treated with foam. Liquid polyurethane is probably the most suitable insulation for steel structures.

Construction foam has good adhesion to any surface. Its heat-conducting properties do not depend on the shape of the walls, and the degree of insulation can be adjusted by the thickness of the layer. The disadvantage can be considered the impossibility of processing at negative temperatures of air and walls.

Materials: properties and comparison

Let's consider several main characteristics that are essential specifically for insulation of warehouses and hangars:

• thermal conductivity, i.e. the degree of insulation of a layer of a certain thickness;
• flammability or the ability to sustain combustion. The security of the premises from fire depends on this parameter;
• specific gravity or the load that the building structure will bear from insulation.

This insulator has the following features:

• specific thermal conductivity: about 0.030 W/m*K. This figure characterizes both glass wool and basalt materials;
• combustibility: do not burn and do not support combustion. Glass wool slabs withstand temperatures up to 400°C without loss of properties, and basalt fiber slabs - up to 1000°C. The walls of the warehouse covered with basalt fiber are able to withstand open fire for a long time;
• specific gravity: depends on the density of the board and ranges from 35 kg/m3 to 180 kg/m3. To insulate a steel wall, 15 cm of a layer with a density of 100 kg/m3 is sufficient. Thus, on a plot of 1 m2, the load will be 15 kg.

Styrofoam and expanded polystyrene

Styrofoam or expanded polystyrene in a solid, slab version have the following qualities:

• thermal conductivity: for polystyrene - 0.037 kg / m3, for expanded polystyrene - 0.027 kg / m3, which is quite comparable with the characteristics of mineral wool;
• degree of flammability: polystyrene foam and expanded polystyrene can burn, however, in modern production, fire retardants are added to them, which allows us to assign a flammability class G1 to these materials and call them non-combustible. The heat resistance of foam materials is low - they do not withstand heating even up to 250-270 ° C, and when burned, they emit gases dangerous to humans;
• specific gravity: foam plastic - 100 kg/m3, expanded polystyrene - 40 kg/m3, polyurethane foam (mounting foam) - 40-80 kg/m3. 1 m2 of foam plastic with a layer of 15 cm will have a weight of 15 kg, polystyrene foam - only 6 kg, and polyurethane foam - from 6 to 12 kg.

Heaters such as mounting or building foam have the same characteristics as polyurethane foam board materials.

Comparative analysis

An elementary comparison of the characteristics shows that the degree of insulation of all materials is almost the same, the minimum weight is polystyrene foam and polyurethane foam. Moreover, the calculation did not include the weight of the frame structure, which is necessary if mineral wool or hard foam material is used. As protection against fire, it is most reliable to use stone wool. However, liquid polyurethane is the easiest to install.

Another important characteristic is the cost of materials. The most expensive are stone wool insulation, the cheapest are foam boards. The choice of thermal insulation for a warehouse depends on the design features, wall material and financial capabilities.

Installation work

The technology of insulation with fibrous and slab materials can be described in the following steps.

The frame is assembled from wooden slats (usually for foam) or metal profiles.

The frame is fastened to the walls either with self-tapping screws or with dowels, metal profiles can be fixed to steel structures using wire and welding. The thickness of the frame elements must correspond to the thickness of the insulation sheets.

To prevent the accumulation of moisture inside the mineral wool layers, it is advisable to place a vapor barrier on both sides, and if the installation is carried out outside the walls, a windproof vapor-permeable membrane. Films should be fastened with slack so that thermal fluctuations in the dimensions of the hangar structures do not damage them.

The frame is usually placed inside the building. However, in order to preserve useful volumes, it is possible to insulate the outside, followed by cladding.

Slab laying

Plates, sheets or rolls are placed between the slats or frame profiles and fixed. Possible joints are carefully sealed with scraps of the same material or foam.

Facing

It is carried out not only to make the appearance more presentable, but also to prevent damage to the insulation. Another technology is used to apply a layer of polyurethane to the walls. The liquid composition is applied by spraying from special sprayers. Work must be carried out in protective clothing, ventilation is organized in the room.

After application, the composition expands on its own for some time and fills all the bumps and cracks in the walls. Freezing time is about 1 hour. As a result, a textured surface appears, which can subsequently be painted with water-based paints.

In many regions, insulated warehouses are needed to store products. They allow you to store products that require certain climatic requirements. Thanks to the presence of such premises, all work related to the long-term storage of agricultural products can be carried out even in severe frosts. Therefore, when designing a building, it is necessary to consider high-quality insulation of the warehouse. This can be done in several ways: choose the design of a two-layer hangar from a metal profile or sheathe the structure with one of the insulating materials. Each option has its own advantages and disadvantages, so they must be taken into account when building a structure.

To keep products in stock, the following conditions must be met:

• adequate air conditioning;
• stable temperature maintenance;
• lack of conditions for the development of pathogenic bacteria.

Reliable insulation of the warehouse will help to achieve this. The following materials can be used for this: polyurethane foam and tepofol. The technology of building an arched hangar in the form of sandwich panels can also be used. Each of the materials used is modern, but has a number of features.

polyurethane foam

Foamed polyurethane insulation is considered a reliable and time-tested material. Its main feature is that it can be applied both to the outside of the structure and to the inside. Reliable processing of walls with such a heater allows you to protect the warehouse from hypothermia and dampness, and prevent overheating of the structure. Due to the characteristics of spraying, it can be applied to any kind of surface.

Benefits of PPU

Among the main advantages of a heater it is worth noting the following:

• affordable price in comparison with similar types of insulation;
• high degree of thermal insulation;
• waterproofing;
• soundproofing;
• aesthetically pleasing appearance;
• the ability to perform any interior decoration;
• material durability (up to 30 years of service);
• lack of joints and seams;
• safety for humans and food stored;
• no weighting for the structure;
• increased elasticity of the material prevents deformation of the hangar.

It not only protects the room from the cold, but also helps prevent overheating of the structure. Sheathing with polyurethane is not only fast, but also cost-effective.

Flaws

Among the shortcomings, one can single out the need to use special equipment for applying sprayed polyurethane foam. At the same time, no work can be carried out in the hangar at the time of installation work.

Violation of the PPU laying technology can lead to the appearance of moisture between the wall and the insulation. Over time, this can provoke the destruction of the wall and, accordingly, the entire structure.

Tepofol

Tepofol heat insulator is available in various types. There are two key categories:

• foil coated;
• with metallized coating.

This is a modern heater with many useful features. In its structure, it resembles foamed polyethylene. Its thickness can vary from 2 to 10 mm.

Advantages

The heater has the following positive features:

• environmental safety, due to the absence of harmful fumes;
• lightness of the material;
• reflectivity up to 97%;
• resistance to decay, mold and harmful fungus;
• lack of threat from rodents and insects.

Due to the porous structure, the material absorbs sounds, while the surface “breathes”.

The foil version of tepofol has the following advantages:

• preservation of the original form;
• mechanical strength;
• hydrophobicity;
• safety for human health;
• good noise absorption;
• long service life;
• resistance to corrosion damage;
• ease of installation.

There are also the following types of insulation:

1. Tepofol type A is available in a roll consisting of a one-sided coating of metallized film. Perfect for insulating ceilings, walls and pitched roofs. It is excellent for thermal insulation of pipelines.
2. Tepofol type B consists of double-sided reflective aluminum foil and polyethylene foam between the layers. It is this structure that completely eliminates all types of heat loss: from thermal radiation to convection.
3. Tepofol type C consists of 4 layers: metallized film, polyethylene foam, adhesive layer and protective film. It protects against moisture and noise and does not require additional laying of vapor barrier material.

Any type of tepofol can be used in regions with temperatures from -60 to +100 degrees.

Flaws

The disadvantage of insulation can be called its vulnerability to mechanical damage. Even slight damage to the film can lead to rupture of the entire layer. In this case, a total replacement of the material will be required.

double layer hangar

The best option is the construction of an insulated version of the hangar for a warehouse. This design resembles a sandwich panel: two sets of arches are erected, one above the other, and insulating material is placed between them.

Advantages

The advantages of a two-layer hangar are:

• higher degree of protection against winds and frosts;
• fire safety;
• protection of the insulating material both outside and inside;
• the ability to choose colors for arches;
• a variety of material filling the space between the arches.

Foamed polyurethane, mineral wool and polystyrene foam are suitable for this type of warehouse insulation.

Flaws

The main disadvantage of this option of warehouse insulation is the high cost of construction. In fact, instead of one, two almost identical hangars are being built.

It is also worth noting that a violation of the technology of installation work can lead to icing in the winter. And mechanical damage to the insulation material will require dismantling and complete replacement of the insulation. If heat exchange is not possible, condensation may occur.

And if the slab exceeds a length of 7 m, it will not be able to withstand the additional load.

Warehouse floor insulation

For reliable protection from cold and frost, you should take care of reliable insulation of the warehouse floor. It is able to reduce the amount of heat loss, maintain the temperature at the required level, improve the soundproofing characteristics of the warehouse, as well as avoid drafts and humidity.

Most often in such arched hangars the floor is concrete. Therefore, insulation is carried out with foam plastic or foam plastic. During the construction process, these works involve the following sequence:

1. Cleaning the area from construction debris, dust and dirt.
2. Ground leveling. Sand can be used if necessary.
3. Laying insulation boards and fixing them.
4. Creating a frame from reinforcement.
5. Pouring concrete layer.

If the floor insulation is carried out after the completion of construction work, such manipulation will require large financial investments, since the laying of the layers will be carried out again. At the same time, in places where transport will operate (forklifts or cars), additional pouring of the floor with concrete will be required.

The best option for warming the floor of a warehouse is considered to be sheet heaters. They are denser and create an additional basis for the reinforcement frame. For these purposes are used.
