It is very difficult to heat a warehouse, especially a large one, even if you do not spare money for heating and put 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 inside the room not only cold, but also heat, it will be quite cool inside in summer.
Warehouses are insulated like the rest. The only difference is that the insulation should be as effective as possible and fit without cold bridges. Remember that money escapes through the cracks and defects in the insulating layer, which can be spent on more needed purposes. Therefore, the choice of materials and technologies must be approached as thoughtfully as possible.
Unfortunately, for the insulation of warehouses, absolutely no products are often offered. suitable materials... Therefore, before ordering a service, you need to understand all the options offered. What you should definitely not agree to:
An excellent option is insulation by spraying polyurethane foam outside or inside 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 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 mildew do not grow on them.
The disadvantages of outdoor insulation are the impossibility of carrying out in the cold season, with strong winds 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 existing valuables and stop work before the completion of insulation and finishing. Fortunately, the polyurethane is quick to apply and dries in a short time. Finishing can be done the very next day after spraying. Therefore, the warehouse will not remain inoperative for a long time.
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 is composed, accompanied by the formation polymer insulation and the release of a large amount of gas. As a result, during spraying, a porous mass is formed, increasing in volume up to 10 times.
When expanded, polyurethane foam fills cracks, irregularities and voids, forming an even layer without joints and seams. Cold bridges are not formed in it either.
Do not be confused by the use of toxic fire hazardous isocyanate in the production of polyurethane foam. 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 in the warehouse unpleasant odor and harmful fumes. The only thing that has to be done is to ventilate the warehouse after the completion of the work.
From above, the insulation is covered with a layer of material that insulates it from ultraviolet rays that decompose polyurethane foam. If desired, the PU foam can be closed with siding or special finishing boards.
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, foam plastic and basalt wool. Therefore, the material can be applied in a layer two times thinner than other insulation materials. This allows you to practically not reduce the area of \ u200b \ u200bthe room and its height. A small thickness of the layer is also obtained due to the lack of cratets necessary for insulation with roll and slab 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 logs and laying damp cotton insulation. PPU is quite durable, therefore, during operation, it does not break and does not crack.
Together with insulation, floor waterproofing is often done, you can read about this in another article ,.
The device of roof structures is divided into attic and non-attic. industrial buildings are made at a slight slope to drain precipitation, usually they are attic. Attic roof types are mainly pitched structures with an angle of inclination of about 30-70 ° and supporting elements in the form of rafters, large panels and trusses.
On the rafters and farms, a crate is laid, often from wooden beam, or boardwalk. It serves as the basis for a roof made of rolled waterproofing materials. Additionally, before laying a roll carpet, if there is such a need, steam and heat insulation is made with special materials.
With spans of 10-12 m, they are built as a system with hanging rafters. It is a structure, the main bearing part of which are trusses supported by the walls of the building. A vertical headstock (suspension) is installed in the center of the farm. It is connected to the walls by rafter legs, which serve as a supporting base for the roof. To impart rigidity to the structure, struts extending from the base of the beam are abutted against them.
For this design, the following materials are most often used:
One- or gable roofs of large ribbed reinforced concrete panels are built with a central support, which can serve inner wall... The panels rest on it and the outer walls of the structure. The span of the structure, as a rule, is 6-6.4 m. Fastening - steel anchors. The panels are coated with asphalt or cement strainer and the rolled carpet is glued. Nowadays, panels are mainly made of waterproof concrete, which does not need waterproofing, so there is no need for it.
Industrial roofs of buildings with a height of more than two floors are fenced with brick parapets.
An industrial roof of a run-free scheme is formed by reinforced concrete slabs, which are simultaneously the supporting element and the base of the roof. Cold roof is built of heavy concrete, after laying the plane is leveled with asphalt mastic or cement mortar with the subsequent gluing of the rolled carpet.
Foam concrete is used for insulation, mineral insulation, a screed is made on top of them and rolled waterproofing is glued.
Sometimes flat roofs do without bias. To avoid overheating, in some cases protection is arranged for them, pouring water 5-15 cm, before the onset of winter the water is drained.
Chimneys and ventilation outlets need a special device for connecting the roof to them. For this, collars are made of tin, adjacent to the pipe, the collar is placed above the plane of the roof. If the coating is asbestos-cement slate, then the collar from the side of the ridge is inserted under the roof, and on the side of the overhang is allowed on top of the slate sheets.
Industrial ones with a height of more than two floors are fenced with brick parapets or gratings according to MRTU 20-4-65.
When talking about thermal insulation of an industrial building, we immediately mean the presence of an aggressive environment, large areas, metal structures and, as a rule, tight deadlines for the execution of work. Therefore, the materials that will be used to insulate an industrial building must:
If there is a question about the insulation of an administrative building, then there are also some requirements:
And in both cases, of course, do not forget about EFFICIENCY. The building must maintain the required temperature regime.
As we can see, the requirements for the insulation of industrial and administrative buildings a lot and they are all pretty serious. But for sprayed insulation, polyurethane foam is not a problem.
It is important to remember that the specifics of thermal insulation industrial buildings due, first of all, to their purpose and location. In all cases, complex work is required to increase the overall thermal protection of the building.
Therefore, it is quite logical that for each separate part of the structure should be used different material suitable for a specific purpose. You can read more about the methods of insulating buildings here. For example, mineral wool slabs with combined insulation are best suited for roofing.
In general, the process of insulating an industrial roof includes several stages:
The load-bearing walls of the structure must be made of bricks, concrete and its varieties (foam concrete, aerated concrete). The structure of these materials has specific features that prevent the passage of cold air.
When using cement or bitumen glue, PPS boards are installed. It is necessary to use only those varieties that are designed specifically for the facades of premises. For greater safety, you can install fire cuttings made of mineral wool.
The final stage is giving the walls the necessary appearance with help decorative plaster... For this, a reinforcing mesh is applied over the slabs, and then a layer of plaster.
This method of insulating the walls of industrial buildings is very popular in Europe. Its peculiarity lies in the fact that after using such technology, it is not required to update the insulation itself. It is enough only from time to time to change the outer decorative layer, which can crumble over the years.
When talking about industrial insulation, it is worth considering the fact that thermal insulation industrial buildings should be comprehensive. In this regard, we must not forget about floor insulation.
Installation of floor slabs to give stability to the future insulated structure.
Laying of EPS boards. Their size depends on the area of the room and is selected in each case individually.
Installation of a waterproofing layer.
The final stage is the screed. Laying of plywood and gypsum fiber in order to increase the thermal insulation properties of the floor, as well as the stability of the entire structure.
This insulation technology is used, as a rule, specifically for reinforced concrete coatings of premises (industrial buildings). She possesses best performance and is designed to increase the coefficient of thermal stability of the building as a whole.
The above methods are classical and give good performance in terms of thermal protection. However, technologies do not stand still, and thermal insulation of industrial buildings also takes on new forms. In particular, this applies to the use of polyurethane foam (PUF) applied by spraying.
Of course, when insulating industrial facilities, there are always many nuances. This also applies to the choice of materials and the method of application (which in turn depends on the purpose of the object and its location).
Ignoring at least one of the points can significantly reduce thermal protection industrial premises, which will inevitably lead to additional costs in the future. The second prerequisite is an integrated approach to the entire industrial facility. If these conditions are met, the best effect is achieved. And the process of insulating an industrial building will be practical and efficient.
Photo: insulated warehouse gates
To insulate the gate in the warehouse, you can use expanded polystyrene or expanded polystyrene. The material is lightweight, durable, not afraid of precipitation. You can use sheets with a thickness of 50 mm, which are inserted into a frame made of 50x50 mm wood bars. The timber is pretreated with an antiseptic, and all the remaining seams between the foam sheets are sealed with polyurethane foam.
When the entire gate area is insulated, moisture-resistant plywood or OSB is mounted on top. The whole technology is no different from the insulation of the garage door. Also, the gate can be insulated with mineral or glass wool, which also fits into a frame made of wood bars. The width of the timber should correspond to the thickness of the thermal insulation layer, which can be calculated on the calculator.
Before laying basalt wool, the entire frame and the gate are closed with a moisture-proof membrane. After laying the insulation, the frame is again closed with moisture insulation, so that the mineral wool is protected from getting wet from all sides. Next, bars are attached to the frame to create a ventilation gap so that moisture evaporates from the surface of the film, and the gate is sewn up with plywood or OSB.
Insulation of the metal roof of the hangar
Insulation of the hangar roof is often difficult because of the considerable height of the structure and its lightness, which is why it is often impossible to use heavy structures. A simpler but expensive way to insulate a roof in a warehouse is to hire specialists who will quickly spray polyurethane foam onto the structure. The polyurethane foam will create a continuous layer without seams and will not load the hangar roof.
A cheaper, but at the same time laborious way is the creation and insulation of the ceiling ceiling. In many cases, this method is simply impossible to implement due to the receipt of significant loads on the lightweight structures of the walls and roof of the hangar. If the warehouse has concrete walls and overlap, then problems should not arise. You can use any roll and slab insulation for this.
Mineral wool or expanded polystyrene slabs should be laid in a pre-designed timber frame. The distance between the bars should be made 1-1.5 cm less than the width of the sheets of mineral wool or glass wool, so that the insulation fits as tightly as possible to the bars. Additionally, the thermal insulation should be fixed with a dowel - with fungi and closed with a vapor barrier to protect it from moisture.
The scheme of insulation of concrete floors on the ground
The concrete floor should be insulated at the stage of the hangar construction. Thermal insulation is produced by the method of warming the earthen floor with polystyrene or polystyrene foam. Insulation plates are laid on the pre-leveled soil (for this, the foundation should be poured from the inside with soil or sand). A caracas from reinforcement is knitted on top, and the floor in the hangar is poured with a thick layer of concrete.
If you need to insulate the floor in the hangar after the end of construction, then this work will require significant financial costs... Since it will be necessary to re-lay the insulation and pour concrete where cars and forklifts will drive. In those rooms where there will be no significant load, you can insulate the floors along the logs, using foam or mineral wool as a heat insulator.
This technology of floor insulation was described in detail earlier in the article "Floor insulation in wooden house which is better ”and will not be difficult. All work on insulating the hangar for the winter from the inside can be done in stages so as not to completely stop the work of the organization.
The issue of warming warehouses is as acute as the problem of reducing heat loss in winter when the doors are open. Sometimes for these purposes, vestibules are used, which significantly complicates the process of loading and unloading. Another popular option is the use of heat guns, which can quickly warm up the air in the room after it has cooled down with the door open.

Warehouses are designed to store various materials and goods. Often, for the storage of certain groups of goods, special conditions are required, including a certain temperature, humidity, and a general microclimate. To create these conditions, the premises must be insulated as much as possible from the effects of environmental conditions, that is, to seal and insulate them. In cold climates, the facades of houses are not able to retain heat inside the premises by themselves. As a result, there are high heating costs, the low efficiency of which is due to the high thermal conductivity of building materials.
Today, for thermal insulation of premises of any type, many modern heaters are used, which are designed to solve various problems. However, for warming warehouses, polyurethane foam, or polyurethane foam, is best suited. This heat insulator has unique characteristics that are not yet available for other materials. In particular, polyurethane foam has the lowest coefficient of thermal conductivity, which makes it possible to recoup investments in thermal insulation in just two seasons, and subsequently to save up to 50% on energy resources for a long time.

PROPERTIES OF POLYURETHANE FOAM, SO NECESSARY IN WARMING A WAREHOUSE
The only drawback of PU foam can be called exposure to ultraviolet rays. However, this problem is solved by simply painting the thermal insulation with any paint that will protect the surface.
Naturally, only thermal insulation of the premises cannot create the necessary microclimate in the warehouse. Therefore, in combination with insulation, it is necessary to take care of high-quality, well-thought-out ventilation. Such a complex will help make your warehouse an ideal place to store any kind of goods.
Most modern private entrepreneurs, as well as various firms, enterprises and factories have warehouses at their disposal. As a rule, finished products are stored in warehouses, goods for sale, expendable materials raw materials and much more.
Whatever is in these structures, if the warehouse is not properly insulated, in a cold winter or hot summer periods the contents of the warehouse run the risk of becoming unusable or losing their original characteristics.
Roof insulation using polyurethane foam has many advantages over other insulation materials:
Due to the unique properties of polyurethane foam, the roof can be insulated both from the outside and from the inside. When applying polyurethane foam to the outer surface of the roof, the polyurethane foam coating must be protected from sunlight. For these purposes, you can use liquid rubber or urethane mastic. Coatings made of these materials will protect the thermal insulation layer of polyurethane foam from ultraviolet rays, create additional waterproofing of the roof and increase its service life.
When using sprayed rigid polyurethane foam for roof insulation in comparison with traditional methods thermal insulation, the time saving is 80%, and the money saving is 50%. In terms of quality and durability, polyurethane foam insulation technologies are many times superior to other insulation methods.
When repairing roofs with polyurethane foam, there is no need to remove the worn-out coating, in addition, all structures present on the roof are additionally sealed, and the absence of thermal bridges prevents the formation of condensation. During the work on thermal insulation of the roof with the use of polyurethane foam, it is not necessary to stop the activity of the entire room, which is also an important advantage of using polyurethane foam.
Polyurethane foam is applied to the surface with a special spray installation high pressure and after a few minutes the polyurethane foam becomes hard.
Whatever material is chosen, it must be firmly fixed to the base. For these purposes, you can use two ways:
Exists building rule, according to which the waterproofing carpet is attached to the insulation in the same way as it is attached to the base. With a mechanical method of fastening, it is better to use a polymer-bitumen weld material as a vapor barrier. Its special elasticity helps to tighten without consequences small holes, inevitably pierced by a dowel, on which the insulation is attached. If a two-layer insulation is used, the slabs must be laid apart so that the joints of the slabs of the lower layer are necessarily covered with the upper one. In this case, the so-called "cold bridges" are not formed. Each insulation plate is fixed with at least two dowels.
Layers " roofing cake»Must be securely fastened
The temperature and comfort inside the building largely depend on the competent insulation of the flat roof. By choosing the right materials and carefully observing construction technology, you can get a magnificent structure that will serve you flawlessly for many years, both as a traditional covering and as a base for a recreation area, terrace or roof garden.
Required resistance to heat transfer.
The selection of the parameters of the enclosing structure is made according to the value of the required resistance to heat transfer, calculated by the formula:
- resistance to heat transfer of the enclosing structure; - calculated air temperature inside the room (); - minimum outside air temperature (); n- the coefficient taking into account the location of the enclosing structure is taken according to the table SNiP -3-79 (taken for the roof n = 1); - the heat transfer coefficient depends on the smoothness of the inner surface of walls and ceilings and takes values according to SNiP (smooth ceilings); - heat transfer coefficient, determined by SNiP (for the roof); - the standard temperature difference between the temperature of the air in the room and the temperature of the inner surfaces of the enclosing structures is adopted according to SNiP (based on the condition "industrial buildings with normal conditions" we accept); R- thermal resistance of the material of construction, determined by the formula
- the thickness of the total layer,
Thermal conductivity for normal operation and normal climate, i.e. Mode A:
Knowing, we derive from the formula (*) the thickness of the roofing materials:
where is the thickness of the insulation, hence,
For roof insulation we use mineral wool mats, and for waterproofing - three layers of roofing material on a bitumen base with a total thickness of 15 mm.
Thermal characteristics of roof insulation materials.
Table No. 2.
- mineral wool mats at density.
As waterproofing:
- roofing material at density and - bitumen at density. From here we find the average value of thermal conductivity for waterproofing:.
Substitute these values into the formula (**):
We round the resulting value to a multiple of 50 mm. Then, the thickness of the mineral wool layer should be at least 0.05 m.
Examination.
Because - the condition for heat transfer of the enclosing structure is met, therefore, the calculation is correct.
Thermal inertia:
- thermal resistance of the i-th layer.
S 1 = 0.46 - heat assimilation of mineral wool, W / (m2 * C);
S 2 = 4.425 - average heat assimilation of roofing material and bitumen, W / (m2 * C);
d 1 = 0.05 - thickness of the mineral wool layer, m;
d 2 = 0.015 - thickness of three layers of roofing material on a bituminous basis, m.
l 1 = 0.05 - thermal conductivity of mineral wool, W / (m * C;
l 2 = 0.19 - average thermal conductivity of roofing material and bitumen, W / (m * C).
Conclusion: for roof insulation we use mineral wool mats, and for waterproofing - three layers of roofing material on a bitumen base with a total thickness of 15 mm.
To fill the window openings, we choose double glazing in metal frames.
Firstly, the thermal conductivity indicators of polyurethane foam are rather low, therefore, even with a small thickness of this insulation on the roof or walls of the building, one can always speak of high efficiency (30 mm of polyurethane foam with a coefficient of 0.019 W / m * K).
Secondly, the closed cellular structure of polyurethane foam does not allow water or steam to pass through, therefore, the water absorption rates of PU foam are also low. And this speaks not only of the preservation of the properties of the insulation
throughout the entire service life, but also on the anti-corrosion protection of metal structures.
Thirdly, the polyurethane foam is mounted using a foam generator by spraying
, which implies the absence of fasteners, guides, as well as acceleration and simplification of the installation process. In addition, the sprayed polyurethane foam is held so tightly that it can only be dismantled by rough physical methods.
Fourthly, polyurethane foam is not afraid of exposure to any chemical reagents (except for concentrated alkalis and acids).
Fifthly, polyurethane foam is applied to the surface with a seamless layer that completely repeats its structure and shape, so you can not worry about a damaged facade. When insulating the facade of a building, PPU can always be painted, plaster applied over it, or a ventilated facade system can be used.
First of all, you should consider the device of a flat roof - insulation can be planned in two ways:
Single layer thermal insulation system. The main distinguishing feature: the entire insulation layer is made of insulation for a flat roof of the same density. If it is planned to arrange an exploited roof, then on top of the heat-insulating layer is laid concrete screed... This system is most often used in the repair of old roofs or in the construction of garages, warehouses and industrial buildings. The two-layer thermal insulation system has a different structure. The top layer with a thickness of 30-50 mm is made of insulation with increased strength and density. It is designed to redistribute mechanical stress. The bottom one, with a thickness of 70 to 170 mm, performs the main heat-insulating function
This design allows you to significantly reduce the weight of the roof and, accordingly, reduce the load on the floors, which is very important when renovating old buildings. Exists modern materials combining the properties of both layers
These paddings have a hard top edge and a softer bottom. Installation of such plates is very fast and reduces the time and labor costs for the installation of the coating.
The two-layer system guarantees no through-seams in the thermal insulation layer
A feature of any warehouse is a huge space, which is often simply impossible to properly heat up to a comfortable temperature for staff. Or perhaps, but then electricity bills will simply go off scale. Therefore, first of all, the warehouse needs to be insulated, to get rid of any “cold bridges”, to close up all the cracks, to think over such a system of loading and unloading goods, which will take the minimum time to open and close the gate.
Warming a warehouse differs from the insulation of an ordinary residential building: it is both huge spaces and work at a height. In addition, not all companies can afford to suspend the activities of the warehouse for some time, and, therefore, work on the insulation of the premises must be carried out at night or directly during the operation of the enterprise.
Let's consider some types of warehouse insulation:
An example of how a warehouse is insulated with polyurethane foam:
See some more examples of such insulation.
Additionally: - "narrow" moment.
After the warehouse is insulated, you can think over the heating system. What we need to know:
Warehouse heating systems can be subdivided into water, steam, air and their combinations (steam-water, water-air, etc.). Let's consider them in more detail.
When heating, there is usually a question of fuel choice. Gas is the cheapest, but diesel, gasoline, and electricity are also used. Electric heating is generally the safest option with
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. Perhaps it is not worth explaining that such a nuisance will bring many problems.
Thermal insulation for pipes is the best way to keep the pipeline from bursting. Of course, it's best to do it before any problems arise. What if the pipes are already frozen? Either defrost them, or replace them, and then insulate them.
The most popular insulation material is polyurethane foam.
Why is it 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. Long lasting. Insulation made from this material can last up to several decades;
4. Easy to install. It is possible to insulate PPU pipes within one day;
5. Inexpensive. Unlike many other materials, polystyrene has an affordable price.

Refrigerated units (industrial cold rooms) must provide sufficient low temperature air creating optimal conditions for storage and transportation of food products, medicines, some types of industrial products. If the thermal insulation of a household refrigerator does not cause difficulties, and can be performed using almost any insulation, then when installing industrial-grade equipment, it is polyurethane foam that is most often used.
The choice of polyurethane foam as the main material used for thermal insulation of mobile refrigerating chambers and large-volume refrigeration units is due to its physical properties and performance characteristics.
The possibility of applying polyurethane foam by a mechanized method and the minimum thickness of the required coating allows you to reduce the production cost refrigeration equipment... Due to this, the price of a refrigerated chamber with polyurethane foam insulation compares favorably with other similar devices of this class.
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 installation. The use of polyurethane foam provides a whole range of operational advantages over other heaters.
Our company carries out thermal insulation of any refrigeration units, including handicraft, polyurethane foam. We guarantee an affordable cost and an increase in the efficiency of refrigeration equipment after the completion of insulation work.

If you are in business, then it is not for us to tell you how important the reliability of warehouse premises is. Just imagine that the frost has hit and your entire product has suffered from it. Similar situations need to be thought out in advance. This will avoid losses.
Warming of warehouses will help to preserve the presentation of your products all year round... This procedure also allows you to save money, since after thermal insulation you will not be able to heat your warehouse as intensively as before. After all, insulated walls keep the heat inside the room.
If you decide to insulate your warehouse, then it is best to choose polyurethane foam for these purposes. It has many advantages:
Ease of installation. Insulation work using this material will take no more than 1 day. Agree that such terms are quite attractive;
Saving. In addition to the fact that your product will always be safe, you can save on heating. Warming of warehouses with polyurethane foam reduces energy costs by 50%. A one-time investment in thermal insulation will save you years of savings;

To get rid of the so-called "cold bridges" in warehouses, it will be necessary not only to seal all the cracks. Considering the fact that such rooms are characterized by a large area, all walls must be well insulated. You should get rid of the phenomenon of warm air leakage.
What is the difficulty?
Today, new warehouses are immediately used in the construction of new warehouses. But what if this is an old room and it is necessary to place goods in it, which in winter time should be stored at freezing temperatures? In this case, you need to think about performing repair and finishing work using insulation. And first of all, you will need to insulate the walls. But whatever 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 are opened almost daily in order to carry out the process of unloading and loading products from freight transport. Therefore, it is necessary to solve two questions at once:
- the gate 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 are large. 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 unable to retain heat. Therefore, first of all, they must be insulated.
Not every warehouse can suspend its activities so that Finishing work for wall insulation 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 very important nuance: many work will have to be done at a height, so you will need optional equipment in the form of a tour - a mobile tower or comfortable stairs.
The main types of warehouse heaters most often used are the following materials:
- mineral wool;
- sprayed polyurethane foam;
- sandwich panels;
- Styrofoam.
Each of these heaters has its own advantages and 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 disadvantages. For example, it is capable of absorbing moisture. In addition, it differs in a decent weight for insulation, which can be dangerous for thin walls made of galvanized steel.
2. Sprayed polyurethane foam is very popular lately. It is able to seal up all cracks, is not afraid of fire, and has low thermal conductivity. It is very easy and quick to apply to walls. But its disadvantage is its high cost. And the warehouse must be stopped for the duration of such insulation.
3. The sandwich panels are very beautiful and strong enough. Their advantage lies in the fact that they do not require further finishing. But from the disadvantages of such a heater, one can single out the laboriousness of the work and their decent weight. And this means that the load will significantly increase not only on the walls, but also on the foundation.
4. Styrofoam is the cheapest insulation. When the walls are insulated, the warehouse may not even be stopped. It also differs in that it is very light. But it also has drawbacks: rodents love it and it is a highly flammable material.
Therefore, it is up to the owner to decide how to insulate your warehouse. In this case, it is necessary to take into account its size and what material it is built from.
