How to insulate a cold warehouse. Warehouse insulation options. Features of industrial thermal insulation using polyurethane foam

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 long-term storage agricultural products can be carried out even in severe frosts. Therefore, when designing a building, it is necessary to consider high-quality insulation warehouse This can be done in several ways: choose a two-layer hangar design from 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 constructing the structure.

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

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

Reliable insulation of the warehouse will help achieve this. The following materials can be used for this: polyurethane foam and tepofol. The technology of constructing 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. His main feature– it can be applied to both outside structures and internal ones. Reliable treatment of walls with such insulation 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 type of surface.

Advantages of PPU

Among the main advantages of insulation it is worth noting the following:

  • affordable price in comparison with similar types of insulation;
  • high degree of thermal insulation;
  • waterproofing;
  • sound insulation;
  • aesthetically attractive appearance;
  • the ability to perform any interior decoration;
  • durability of the material (up to 30 years of service);
  • absence of joints and seams;
  • safety for humans and food products 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 prevents the structure from overheating. Sheathing with polyurethane is not only fast, but also cost-effective.

Flaws

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

Violation of the technology for laying polyurethane foam 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 thermal insulator is available in various types. There are two key categories:

  • coated with foil;
  • with metallized coating.

This is a modern insulation with many useful characteristics. Its structure resembles foamed polyethylene. Its thickness can vary from 2 to 10 mm.

Advantages

The insulation has the following positive features:

  • environmental safety due to the absence of harmful fumes;
  • lightness of the material;
  • reflectivity reaching 97%;
  • resistance to rotting, mold and harmful fungus;
  • no threat from rodents and insects.

Thanks to its 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.

Also distinguish the following types 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 roof. It is perfect 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 installation 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 is its vulnerability to mechanical damage. Even minor damage to the film can lead to rupture of the entire layer. In this case, a complete replacement of the material will be required.

Double layer hangar

The best option is to build an insulated hangar for a warehouse. This design is reminiscent of sandwich panels: two sets of arches are erected, one above the other, and insulation material is placed between them.

Advantages

The advantages of a two-layer hangar are:

  • higher degree of protection from winds and frost;
  • fire safety;
  • protection of insulating material both outside and inside;
  • choice color solutions for arches;
  • variety of material filling the space between the arches.

Foamed polyurethane, mineral wool and expanded polystyrene are suitable for insulating a warehouse of this type.

Flaws

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

It is also worth noting that violation of installation technology can lead to icing in winter period. Mechanical damage to the insulating material will require dismantling and complete replacement insulation. If there is no possibility of heat exchange, condensation may occur.

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

Warehouse floor insulation

For reliable protection from cold and frost, care should be taken to ensure reliable insulation of the warehouse floor. It can reduce the amount of heat loss, maintain the temperature at the required level, improve the soundproofing characteristics of the warehouse, and also avoid drafts and humidity.

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

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

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

Sheet insulation is considered the best option for insulating warehouse floors. They are denser and create an additional basis for the reinforcement frame. Used for these purposes.

Thermal insulation of pipes in our country is practically necessary procedure. The fact is that in winter the air temperature drops quite low. Severe frost may simply “break” the pipe. There is probably no need to explain that such a nuisance will bring many problems.

Thermal insulation for pipes – The best way 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 then insulate them.

WHY IS PUF 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 through 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. Insulation of polyurethane foam pipes can be done within one day;

Insulation of containers and tanks with polyurethane foam

A metal container is used not only as a container for transportation. Outlets, small warehouses, garages, tanks for storing water supplies - and this is not a complete list possible options applications. Such a wide range of applications was ensured by the low price, ease of installation, and the ability to move to the required point. The only drawback of containers is the almost zero thermal insulation of this design, and the use of most traditional insulation materials leads to a significant reduction in the internal volume of the container. This problem can be solved by spraying polyurethane foam, a two-component material of a new generation that provides thermal insulation with a minimum thickness of insulation.

Insulation of containers with polyurethane foam

Insulating containers with polyurethane foam is a technically simple process, but it requires the use of special, expensive equipment. In this regard, the cost of spraying is slightly higher than the cost of installation. slab insulation, the economic effect of the technology is based on the improved performance properties of the material.
  • Installation does not require the use of additional fasteners. Polyurethane foam is applied directly to the metal surface of the container, making it possible to abandon the traditional frame.
  • An insulation system made of polyurethane foam does not require the use of hydro- and vapor barriers, which significantly simplifies installation, increases the speed of its implementation and reduces the cost of purchasing materials.
  • Polyurethane foam protects the metal container from moisture, thereby reducing the risk of corrosion, which increases the service life of the structure.
  • We recommend installing polyurethane foam insulation from the inside, minimum thickness layer will not reduce the useful volume of the structure, and the protection of polyurethane foam from sunlight simple painting will provide.
  • Polyurethane foam insulation is distinguished by its environmental safety, which is why its use is recommended for food outlets (unlike materials based on fiberglass and mineral wool).
Before installing thermal insulation, the surface of the container must be cleaned of existing pockets of corrosion; it is also advisable to prime the cleaned areas with special compounds. No other preliminary surface preparation is required.
The polyurethane foam mixture supplied under pressure penetrates into all existing cracks and recesses, thanks to this inner surface container, a continuous coating is formed, differing minimal heat loss. The spraying speed is quite high; our specialists process an average-sized object in just one day, and work can be carried out at any time of the year. In just a few hours, the polyurethane foam reaches its design hardness and strength, and the container can be used for its intended purpose already on the day the thermal insulation is installed.

insulation of tanks with polyurethane foam

Installation of insulation on tanks is complicated by its cylindrical shape. For fastening traditional slab or roll materials requires fairly complex construction frame structures. That is why the use of polyurethane foam for such work is considered the most rational. 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 polyurethane foam will provide reliable protection from exposure to soil water and other aggressive liquids.
Treatment of the tank with polyurethane foam allows you to organize storage various liquids, prone to freezing, even in harsh climatic conditions. Thermal insulation of this class is also used when installing fire tanks to provide water reserves for fire extinguishing needs.

Our company provides thermal insulation of containers for various purposes and tanks throughout Moscow and the Moscow region.

Insulation of vegetable stores with polyurethane foam

A large city needs a large amount of food. That is why the construction and operation of premises for storing grain, fruits, and vegetables is quite profitable business. The most efficient vegetable storage facility is considered to be a prefabricated building with polyurethane foam insulation. The structure can be installed quickly, has a significant useful volume, and provides the necessary storage for various products. temperature regime Spraying polyurethane foam, which has good thermal characteristics, will help.

Types of vegetable stores with polyurethane foam insulation

Representatives of the agro-industrial complex appreciated all the advantages of thermal insulation based on polyurethane foam. Thanks to the advent of such insulation, it became possible to construct reliable vegetable storage facilities from almost any building. Today, the following types of similar facilities are successfully operated in the Moscow region:
  • Vegetable storage facilities based on prefabricated metal hangars and large-volume containers.
  • Converted brick and wooden buildings with double or single insulation using polyurethane foam.
  • Basement and ground floors industrial buildings, which, with minimal reconstruction, perform the functions of efficient and inexpensive vegetable storage facilities.

6 reasons to choose polyurethane foam insulation

At the moment, polyurethane foam is gradually replacing construction market other existing insulation. Experts explain the large volume of use of polyurethane foam in the construction of vegetable storage facilities for the following reasons:

1. The ability to insulate buildings from various materials. Polyurethane foam fits perfectly on metal, wood, concrete and brick surfaces. At the same time, spraying polyurethane foam does not require expensive preparatory work and installation of load-bearing frames. Thanks to this, the cost of constructing or reconstructing a vegetable storage facility is significantly reduced.
2. The use of high-performance equipment for applying foam can significantly reduce the installation time of thermal insulation. Professional installer capable of processing up to 350-400 m2 of vegetable storage area per shift.
3. Thermal insulation made of polyurethane foam has minimal moisture absorption and vapor permeability, thanks to which you can create a microclimate that is optimal for storage various products, while the need for additional installation There are no insulating coatings.
4. A vegetable storage facility, insulated with polyurethane foam, ensures the safety of products at both negative and high positive ambient temperatures. Individual rooms of the building can be converted into efficient freezers.
5. Insulation based on polyurethane foam is characterized by significant durability; while providing protection from sunlight (which can be achieved by simply painting the insulation), the operational life of the thermal insulation reaches 30-50 years.

THERMAL INSULATION OF REFRIGERATION CHAMBERS WITH POLYURETHANE FOAM

Refrigeration units (industrial refrigeration chambers) must provide sufficiently low air temperatures to create optimal conditions for storage and transportation of food, medicine, and some types of industrial products. If thermal insulation household refrigerator does not cause difficulties and can be done using almost any insulation, then when installing industrial-grade equipment, polyurethane foam is most often used.

Reasons for choosing polyurethane foam for the installation of refrigeration chambers

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

  • The small specific gravity of the insulation based on polyurethane foam allows the installation of refrigeration units on the basis of ordinary freight vehicles; such thermal insulation does not create additional load on the vehicle chassis.
  • The 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 circulates the refrigerant.
  • Insulation using polyurethane foam can be carried out both in the factory and in the place where the refrigeration chamber is directly installed. It is thanks to this that thermal insulation industrial installations in logistics and shopping centers performed by spraying polyurethane foam. The small dimensions of the unit allow you to perform work both outside and inside the industrial refrigerator.
  • Two-component polyurethane foam can be applied in several layers without disturbing the integrity of the coating. This allows for thermal insulation required thickness(determined by calculation of thermal characteristics and the required operating mode of the refrigerator). In this case, spraying is carried out in a seamless manner, which significantly reduces heat loss from the installation.
  • Minimum moisture absorption and vapor permeability of polyurethane foam allows you to create refrigeration chamber the most optimal microclimate for storing various products. This significantly reduces the likelihood of condensation forming on the surfaces of the installation.

Possibility of applying polyurethane foam mechanized way and the minimum thickness of the required coating allows to reduce the cost of production refrigeration equipment. Thanks to this, the price of a refrigerator chamber with PPU thermal insulation compares favorably with other similar devices of this class.

Advantages of a refrigerator with thermal insulation made of polyurethane foam

First of all, it should be noted that polyurethane foam is absolutely harmless to 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 insulation materials.

  • Thermal insulation made of polyurethane foam is not of interest to rodents, which ensures reliable safety of the structure.
  • The thermal characteristics of the installation do not deteriorate over time. Unlike rolled mineral wool or PU slabs, it does not slip off vertical surfaces. Average term The operation of a refrigerator insulated with polyurethane foam exceeds 50 years, while the payback period of the installation at an above-average load ranges from 2 to 5 years, depending on the working volume.
  • To increase the energy efficiency of equipment, double spraying of polyurethane foam (external and internal) is practiced. This technique makes it possible to ensure the necessary thermal performance with a minimal reduction in the working volume of the chamber.
  • Insulation with polyurethane foam makes it possible to minimal costs convert almost any room into a refrigeration unit. In this case, the main share of expenses will be on the purchase of a refrigeration machine (compressor); the cost of applying polyurethane foam (even taking into account the price of the material) is significantly lower.

Our company provides thermal insulation of any refrigeration units, including handicrafts, polyurethane foam. We guarantee an affordable price and increased efficiency of refrigeration equipment after insulation work is completed.

Practical insulation for warehouses

Operational properties and installation technology allow us to consider foamed polyurethane insulation as effective solution for thermal insulation of warehouse premises.

The main properties of insulation include:

  • long service life;
  • water resistance and heat resistance;
  • low thermal conductivity;
  • resistance to rodents;
  • 100% adhesion to any type of substrate.

The polymer material is environmentally friendly and equally effective for external and internal insulation.

PPU installation technology

Foamed polyurethane is applied by spraying using special equipment. This method allows you to create a seamless coating of the required thickness on surfaces of any complex shape. Due to good adhesion, the material is installed without lathing and the use of mechanical fasteners. The hardening time of the foam does not exceed several hours. The method of application and the absence of fasteners make it possible to extremely reduce time losses on thermal insulation.

Insulation of warehouses in Moscow and the Moscow region

By contacting our company, you can place a profitable order for fast and high-quality insulation of warehouse premises. We have good prices for services and offer discounts.

A feature of any warehouse is a huge space, which is often simply impossible to properly heat to a temperature comfortable for the staff. Or perhaps, but then the electricity bills will simply go through the roof. Therefore, first of all, the warehouse needs to be insulated, get rid of any “cold bridges”, seal all the cracks, think over a system for loading and unloading goods that will take the minimum time to open and close the gates.

Warehouse insulation

Insulating a warehouse differs from insulating an ordinary residential building: it involves both huge spaces and work at heights. In addition, not all companies can afford to suspend warehouse operations for some time, and, therefore, work on insulating the premises must be carried out at night or directly during the operation of the enterprise.

Let's look at some types of warehouse insulation:

  1. Mineral wool. This classic way, quite cheap and therefore popular. Mineral wool is fireproof and does not rot. Its disadvantages are the high ability to absorb moisture and the high weight of the slabs, which can be dangerous for walls made of thin galvanized steel (hangars).
  2. Sprayed polyurethane foam. IN Lately This is a very popular method of insulating warehouses. Polyurethane foam is non-flammable, has low thermal conductivity and high vapor barrier, it is easy and quick to apply, it forms a dense, seamless coating without any “cold bridges”. Its disadvantage is the rather high cost and the impossibility of carrying out work in a functioning warehouse.
  3. Sandwich panels. The finished factory panels are very beautiful, quite durable and do not require additional processing. The disadvantage of sandwich panels is the complexity of their installation and high weight, which can create additional load on the walls and foundation.
  4. Styrofoam. Very cheap way, foam plastic slabs are easy to install even when the warehouse is running. The disadvantage is that the material is highly flammable.

An example of how a warehouse is insulated with polyurethane foam:

See some more examples of such insulation.

Additionally: – “narrow” moment.

Warehouse heating

After the warehouse is insulated, you can think about the heating system. What we need to know:

  1. Warehouse parameters: width, height, length.
  2. The right temperature. It is very important to know in combination with the outside temperature - in order to calculate the delta by which we need to warm the warehouse.
  3. Heat dissipation coefficient - how the room is insulated.

Warehouse heating systems can be divided into water, steam, air and their combinations (steam-water, water-air, etc.). Let's take a closer look at them.

  1. Water heating. A complex and expensive to install system consisting of heating point, highways connected to it and separate risers with heating devices. The advantage of this method is uniform and low heating, normal air humidity in the room.
  2. Steam heating. Provides quick heating of the room, requires less space heating devices. Disadvantages: complicated installation, short service life of the system.
  3. Air heating. High efficiency, easy installation, low cost. Flaws - large diameter air ducts
  4. Thermal curtains. Help to separate warm air indoors from the cold outside when opening gates or warehouse doors. Air-thermal curtains prevent the movement of air masses and allow you to maintain the temperature regime inside the storage facility.

When heating, there is usually a question of choosing a fuel. Gas is the cheapest, but diesel, gasoline, and electricity are also used. Electric heating is generally the safest option with

It is very difficult to heat a warehouse, especially a large one, even if you spare no expense on heating and install a couple of heat guns. Without carrying out insulation work, all these attempts will turn into a lot 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 prevents not only cold but also heat from entering the room, in the summer it will be quite cool inside.

How to insulate a warehouse

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

Unfortunately, for the insulation of warehouses, completely inappropriate materials are often offered. suitable materials. Therefore, before ordering a service, you need to understand all the options offered. What you definitely shouldn’t agree to:

  • Various varieties mineral wool . Many companies point out as a plus that these materials have been used for a very long time. Consider whether you need outdated technology. The thermal conductivity index of 0.040 W/(m*K) was previously considered excellent, and for this reason one had to put up with the disadvantages of mineral wool - increased moisture absorption and installation complexity. When used, they even ignored the facts that one type of mineral wool - the so-called glass wool - causes damage to the respiratory tract of the skin and eyes, and other options contain harmful phenol. Cheap mineral wool, which smells unpleasantly of phenol and formaldehyde, is especially dangerous. It is impossible to insulate the warehouse with it - the staff will feel uncomfortable being there, and the stored property will acquire an unpleasant smell of paint and hospital. Nowadays, when there are more effective, simpler and safer 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 opportunity to receive additional profit;

  • - another material often proposed for insulating warehouses. The panels consist of two layers of plastic with insulation sandwiched between them. Sandwich panels are harmless to health and do not emit odors. However, the material has a serious drawback - the difficulty of installation caused by its poor ductility. Sandwich panels are quite rigid, so they cannot be bent. You have to cut the insulation into small fragments that are connected to each other. This leads to the formation of cold bridges at the joints, through which cool air penetrates into the warehouse. Another disadvantage of sandwich panels is their heavy weight, which gives high load on the foundation and walls. In addition, sandwich panels burn. Therefore, if a short circuit in the wiring occurs in a warehouse, the building will burst into flames, releasing acrid black smoke;

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

  • good material, which has a high energy saving rate, but, unfortunately, is very expensive. In addition, it requires the construction of various lathing 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 on the outside or inside of the walls. External insulation is much preferable, since it allows the warehouse to continue operating. In this case, the dew point - the area inside the wall where water vapor turns into water - does not reach the interior. 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 mildew do not grow on them.


Disadvantages of external insulation - impossibility of carrying out in the cold season, when 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 choose internal insulation. True, in this case you will have to unload the entire warehouse, remove all existing valuables and stop work until the insulation and finishing are completed. But, fortunately, polyurethane is quickly applied and dries within a short time. Finishing can be done the very next day after spraying. Therefore, the warehouse will not remain closed for a long time.

How to insulate a warehouse with polyurethane foam

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

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

Don’t be confused by the use of toxic, flammable isocyanate when producing polyurethane foam. The polyurethane foam resulting from this 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 stock unpleasant odor and harmful fumes. The only thing you have to do is ventilate the warehouse after completion of the work.

The insulation is covered on top with a layer of material that insulates it from ultraviolet rays, decomposing polyurethane foam. If desired, PPU can be covered with siding or special finishing boards.

Polyurethane foam has one of the lowest thermal conductivity rates - 0.020 W/(m*K), which is two times lower than that of mineral wool, foam plastic and basalt wool. Therefore, the material can be applied in a layer twice as thin as other insulation materials. This allows you to practically not reduce the area of ​​​​the room and its height. The small thickness of the layer is also due to the lack of lathing necessary for insulation with roll and slab materials.

This material can also be used to insulate the floor of a warehouse. This technique is much more effective than filling expanded clay between the joists and laying damp cotton insulation. Polyurethane foam is quite durable, so it does not break or crack during use.

Along with insulation, the floor is often waterproofed; you can read about this in another article.
