Today, the reduction in heat loss has become more acute due to rising prices for public utilities and for coolants. This issue is especially relevant for buildings and structures that require a lot of thermal energy to heat. For example, when transporting media along highways in which the heat pipes are not insulated, about 20% of the heat is wasted. Consequently, utility companies do not receive these funds. And poor thermal insulation of TRP further increases heat losses. If we proceed from the personal considerations of the owners of trucking stations, car washes, office centers and other buildings, then due to poor thermal insulation, decent amounts literally disappear into the air. After all, the heating season lasts almost six months for us and poor quality thermal insulation of heat pipes and structures causes millions of losses and ecowool can reduce these losses.

IN recent years Considerable attention is paid to thermal insulation and energy-efficient technologies, so the development of ecowool production technologies in our country is becoming very relevant and makes a significant contribution to increasing the efficiency of the economy as a whole.

Advantages of cellulose insulation:

• weighs little;
• fireproof;
• does not absorb moisture well;
• does not rot or mold.

Ecowool - the best choice

Firstly, insulating ecowool is very inexpensive. Secondly, the reduction in heat loss when using it exceeds other insulation methods. In addition, for buildings that are practically bulkhead-free structures, any thermal insulation using conventional methods (for example, using mineral wool or glass wool) is a load on structural elements and on the foundation. This load, in particular when insulation of hangars or warehouse can ultimately lead to deformation of the walls, especially during periods when thermal insulation material absorbs moisture. Ecowool practically does not absorb moisture (even at 100% air humidity, water penetrates only into the outer layers). The weight of ecowool is so small that it is not a significantly significant value for insulation.

Ecowool - insulation of hangars, warehouses, car washes

For car washes and warehouses, such an aspect as room humidity is very important. Insulating ecowool absorbs moisture in very small quantities, but this water does not remain in the spaces between the fibers, but penetrates deep into them. Therefore, this water does not drain, forming non-drying puddles, but remains inside the fibrils, waiting for a period of decreased air humidity. When insulating hangars with ecowool, you don’t have to worry that the equipment in them will rust. When atmospheric humidity drops, cellulose thermal insulation begins to gradually release water to the outside. During this period, mold or putrefactive microorganisms will not have time to develop in the thermal insulation of a warehouse or car wash. After all, ecowool is pre-treated with antiseptics. There is no reduction in heat loss even at high humidity, since air remains between the fibers.

Thermal insulation of warehouses and motor transport enterprises should take into account the flammability of the material. The same applies to the insulation of equipment hangars. Another advantage that the owners of these structures receive when using ecowool as a heat-insulating material, is that it does not support combustion and is capable of self-extinguishing. For this purpose, ecowool is specially treated with fire retardants.

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 consider 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. Recently, this has been 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” point.

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 and requires a smaller area of ​​heating devices. Flaws - complex 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 preserve temperature regime inside the storage.

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

Insulating a polyurethane foam warehouse is beneficial

Many shopping complexes manufacturing companies, shops and companies require their own warehouse space. The key task of such structures is to ensure proper storage conditions various cargoes. The warehouse must comply with established storage standards to avoid damage to the cargo and changes in its parameters. Maintaining a certain temperature and humidity conditions in a warehouse is a top priority for every business owner. An uninsulated warehouse leads to a lot of trouble. There is a problem with maintaining desired temperature, as a result of which the storage conditions of goods are violated and the work of equipment and people is hampered. Condensation forms, leading to rust on equipment, rotting of ceilings and dampness of stored products. As a result, electricity costs increase and company losses increase. This kind of consequences can only be avoided through competent management.

Insulating a warehouse with polyurethane foam effectively solves a number of problems. This option is rightfully considered one of the best from a technological and economic standpoint. Sprayed polyurethane foam has a mass positive aspects, which sets it apart from other outdated alternatives: polystyrene foam, fiberglass, basalt wool slabs.

Warehouse before and after applying polyurethane foam

Insulating a warehouse is a rather complex and costly process. Difficulty of thermal insulation storage facilities due to their design features. Typically, such structures are based on prefabricated frame structures with an arched dome shape. Standard methods thermal insulation of the premises, applicable for residential buildings, is unprofitable here. In many cases, they do not achieve the desired result. Highly effective modern techniques come to the rescue - insulating the warehouse with polyurethane foam.

Insulating warehouses using the indicated method provides many advantages. The material is easy to apply. The composition, the components of which are liquid polyol and isocyanate, is sprayed onto the surface under high pressure. When applied, it increases in volume many times over and hardens almost instantly. Therefore, insulation of large warehouses can be done in a day with just two people. The material has the lowest thermal conductivity coefficient in comparison with other building materials - 0.019 W/M*K.

Polyurethane foam can be applied to surfaces made of iron, concrete, and brick that have not been previously prepared. A frame is not required for this, nor is the use of special fasteners. The shape of such surfaces does not matter - the material fits perfectly into all the recesses, filling them with itself. The complex geometry of a warehouse will not be a problem for this polymer. It fits snugly to all surface irregularities.

Insulating a polyurethane foam warehouse is beneficial from an economic point of view due to the fact that the material minimizes heat loss and energy consumption. The resulting coating has no seams, gaps, or joints. The polymer layer is equivalent brickwork 500 mm thick. At the same time, for insulation of warehouses, a coating with a thickness of 50-80 mm is quite sufficient. This ensures savings usable area necessary for storing products, cargo, etc.

The advantages of polyurethane foam are obvious:

It is not afraid of moisture, which eliminates the need for waterproofing.

Incombustible. The material is not flammable and does not support combustion. Garage insulation with polyurethane foam provides fire safety designs.

Capable of effectively filling all existing voids.

Provides good sound insulation.

Protects metal structure garage from the emergence and spread of corrosion processes.

Thermal insulation is completely moisture-proof, there is no formation of gas condensation, the development of fungus and plaque. Low material density leads to reduced total load on load-bearing structures. The cellular structure of the material ensures proper vapor permeability of the heat insulator. This guarantees the absence of dampness and mold, which is especially important during storage. food products in stock.

PU foam does not react with water and chemicals. Excellent adhesion of the polymer ensures an excellent connection between the heat insulator and any type of wall.

PUF is environmentally friendly and safe for health. It does not contain harmful impurities. It can be freely used for insulating food warehouses. It is resistant to combustion and temperature changes, and successfully copes with both frost and heat. The flammability class of the material ГЗ guarantees that it is not capable of becoming a source of fire and does not support the combustion process. The created thermal insulation can last 30-50 years without any repairs.

This material organically combines excellent heat, noise and waterproofing. Insulation of a PPU warehouse is an excellent way to ensure high-quality thermal insulation of this type industrial facilities at maximum speed carrying out work over large areas.

Any warehouse is characterized by a huge space. Therefore, it is very difficult to heat it - to create comfortable temperature. After all, in this room people work, materials are stored and mechanisms operate, for example, scissor lift tables. If this problem is solved only through powerful heat sources, then the bills for consumed electricity will be huge. That is why such a room needs to be properly insulated. It is necessary to eliminate all “cold bridges”, seal the cracks and, if possible, keep the gate open for a short time.

Warehouse insulation

This type of room is insulated quite differently from ordinary housing. Here you need to take into account the huge space and work at height. In addition, it is not always possible for an enterprise to stop the operation of a warehouse for insulation. As a rule, such work is carried out at night or during the performance of basic functions. To insulate a warehouse, you can use the following materials:

1. Mineral wool is a cheap and popular insulation material. This material not fire hazardous and does not rot. But cotton wool can absorb moisture. The basis for such a material must have high strength.
2. Polyurethane foam is a sprayed material. It is not flammable, is a good vapor barrier, and has low thermal conductivity. Easy to apply without leaving seams. There are no “cold bridges”. This material is expensive. It is impossible to carry out insulation work without shutting down the warehouse.
3. Sandwich panels are a durable material that does not require processing. Disadvantages: high weight, difficult installation, heavy load on the walls.
4. Polystyrene foam is a cheap, lightweight insulation material. Easy to install.

It is very important to properly insulate the gate. The following materials are used for this:

1. Expanded polystyrene sheets.
2. Mineral wool slabs.

Insulation of gates with polystyrene foam

To do this, use dense foam plastic 50 mm thick, self-tapping screws and timber 50x50 mm. First, you need to treat the timber with an anti-fungus and mold remover. After the timber has dried inside The gate is made from it and a lathing is installed. Since the width of the foam sheet is 50 cm, then vertical bars fasten in increments of 49.5 cm. If you do not comply with this size, you will have to arrange additional fastening. Gaps that may form after completion of this work must be filled with construction foam. After this, this insulation must be covered with any sheet material (plywood, tin).

Insulating gates with mineral wool

Metal gates need to be cleaned from the inside. Next, holes are drilled and the timber sheathing is installed (100 cm increments) using self-tapping screws. Insulation boards must be cut so that their width is 3 cm greater than the pitch of the beams. Mineral wool slabs are placed into the resulting timber cells (using glue). Sheet material that is not afraid of moisture is fixed on top of the insulation.

How to reduce heat loss when opening gates

One of the ways to retain heat when the gate opens is to install an intermediate vestibule. However, this method is not entirely convenient because it complicates the process of moving goods. The bath problem can also be solved using a heat gun. In this case, a sensor is installed on the gate. As soon as the gate is opened, the heater immediately turns on, which works until the gate closes (and for some time).

For development industrial production, wholesale trade, the logistics business always requires the availability of warehouse space of decent size. In addition, warehouse stores and online trading platforms that do not have separate areas for selling goods.

What's the problem?

Of course he doesn't imagine special labor erect a small warehouse building from materials that already have heat-saving properties. But if we're talking about on areas and volumes for organizing the storage of products, raw materials or goods, amounting to hundreds and thousands of square and cubic meters, That traditional ways construction will not be economically justified.

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

The steel sections do not retain heat at all in winter and do not protect the internal volume from heating in the sun in summer. There are also storage structures made from concrete slabs, also requiring 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 methods for preserving heat in a warehouse, several basic ones that are acceptable in terms of efficiency deserve attention.

Method 1: Creating an Inner Outline

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

Installation can be done according to various technologies- using wooden slatted 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 in the usable area of ​​the warehouse and the high cost of the structure.

Method 2: insulation with basalt and glass wool slabs

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

This places additional stress on the hangar sections and may affect its stability. In addition, it may be difficult to attach slats or profiles to steel walls. Another disadvantage of this method is that moisture inevitably accumulates in the thickness of the insulation and does not escape.

Method 3: foam as insulation

Polyurethane foam insulation has become popular. This material exists in two forms - in the form of slabs and in the form of a liquid mixture, which foams on its own after application. Plates are used to insulate the external surfaces of wooden or concrete walls, and foam is used to treat indoor walls. Liquid polyurethane is probably the most suitable insulation for steel structures.

Construction foam has good adhesion to any surface. Its thermal conductivity 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 inability to process when negative temperatures 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 ability to sustain combustion. The fire protection of premises depends on this parameter;
• specific gravity or the load that will be borne by building structure from insulation.

This insulator has the following characteristics:

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

Polystyrene foam and polystyrene foam

Polystyrene foam or expanded polystyrene in solid, slab form have the following qualities:

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

Insulation type mounting or construction foam have the same characteristics as slab polyurethane foam materials.

Comparative analysis

A basic comparison of characteristics shows that the degree of insulation of all materials is almost the same; polystyrene foam and polyurethane foam have the minimum weight. Moreover, the calculation did not include the weight of the frame structure, which is necessary if mineral wool or hard foam material. What is the safest way to use fire protection? 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 plastic) or metal profiles.

The frame is fastened to the walls either with self-tapping screws or with dowels, metal profiles can be attached 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. The films should be secured with slack so that thermal fluctuations in the dimensions of the hangar structures do not damage them.

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

Laying slabs

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

Facing

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

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