Material description

Bikrost is a waterproofing sheet consisting of a solid base on which a mixture of bituminous binder and fillers is applied. The material is intended for the installation and repair of roofing carpet.

Bikrost K is used for the device of the upper layer of the roofing carpet. Coarse-grained dressing on the front side protects the material from exposure to sunlight.

Bikrost P is used as a vapor barrier when installing a roofing carpet (the bottom layer of the system). Fine-grained dressing or film can be used as a protective layer of the material.

Bikrost material can be used in all climatic regions (according to SNiP 23-01-99 *).

Application area:

Designed for waterproofing buildings, structures and building structures.

Structure:

Bikrost is obtained by double-sided application to fiberglass (fiberglass, perforated fiberglass, frame fiberglass) or polyester base of bitumen binder, consisting of bitumen and filler, followed by application of protective layers on both sides of the canvas. Coarse-grained (shale, asbagal), fine-grained (sand) dressing and polymer film are used as protective layers.

Stamps:

Depending on the type of protective layers and the area of \u200b\u200bapplication, Bikrost is produced in two grades:

Bikrost K- with coarse-grained dressing on the front side and polymer film on the underside of the web; it is used for the device of the upper layer of waterproofing with sun protection;

Bikrost P- with fine-grained dressing or polymer film on the front side and polymer film on the lower side of the web or fine-grained dressing on both sides of the web; it is used for the device of the lower layers of waterproofing.

Manufacturing jobs:

According to the "Guidelines for the design and construction of roofs made of bituminous materials of the roofing company" TechnoNIKOL "", it can be used in all climatic regions according to SNiP 23-01.

From time immemorial, performing waterproofing work was considered hard and dirty work, the craftsmen had to work with a large amount of liquid tar, bitumen, inhale the soot and fumes of resin combustion products. With the advent of roll roofing materials such as Bikrost Technonikol, the work has not only become cleaner, the quality and technical characteristics of the waterproofing layer have improved by an order of magnitude.

What materials are used for laying a soft roof

Among several dozen varieties of roll materials for waterproofing from the TechnoNIKOL company there is plenty to choose from, but the dry characteristics and description in the product catalog give a vague idea of \u200b\u200bthe advantages and disadvantages of the Bikrost soft roof.

Today, there is considerable practical experience in the use of Technicol products, on the basis of which we can advise a pair of typical waterproofing coatings that have proven themselves from the best side, widely used for roofing work:

"TechnoNIKOL Bikrost HKP" - roll waterproofing with a protective surface layer of shale or granular sand;
"Technonikol Bikrost HPP" - almost identical in structure to the previous coating, but instead of a protective powder, a protective polymer film is glued to the "HPP".

Both waterproofing options are made on the basis of perforated fiberglass, with a double-sided layer of bitumen rolled onto the base, oxidized and modified to increase viscosity with rubber-like fillers.

Important! The overwhelming majority of Bikrost coatings, including KhKP and KhPP, are designed for use in all climatic zones of Russia.

Use and technical characteristics of "Bikrost HPP"

Roofing covering "TechnoNIKOL Bikrost HPP" by its price and technical characteristics can be attributed to materials of economy class. The relatively low price of the canvas "HPP", from 50 to 70 rubles per m2, is successfully combined with the high mechanical characteristics of the canvas and bitumen layer.

Performance characteristics of "TechnoNIKOL Bikrost HPP"

To find the optimal conditions for roofing work, you should pay attention to the main characteristics of the material "TechnoNIKOL HPP":

For rupture, the control sample of the Bikrost HPP web can withstand a load of at least 30 kg in the transverse direction, without violating the integrity of the reinforcing tape and the bitumen layer;
High temperature and operational characteristics of the "HPP" roofing sheet allow avoiding deformation, spreading, cracking or delamination of the material. Sample "HPP" exhibits brittleness of the bitumen layer at temperatures below 15 o C. At 0 o, the canvas can still be bent on a blank 25 mm in diameter without much effort;
The insulating layer "Bikrost TechnoNIKOL HPP" shows good characteristics of resistance to water absorption and water permeability. In 24 hours, the sample completely immersed in water was able to absorb moisture no more than 1% of its own weight.

Advice! Roofing "HPP", in contrast to the "HKP" series, does not have a protective surface layer of powder, so you should not once again roll out the roll or step on the panel, especially at low temperatures.

Practical use of waterproofing "TechnoNIKOL Bikrost HPP"

First of all, it should be noted that the "HPP" material is very rarely used independently for arranging a soft roof. It can be used to overlap walls and cornices in the area where the roof is attached, aprons can be applied in the contact area with ventilation pipes, aerators and other elements installed on the roof. The thickness of 2.6 mm and the absence of external powder make Bikrost KhPP an ideal substrate for the main layer of waterproofing made of EKP or HKP.

If it is necessary to perform a single-layer waterproofing or a soft roof from "HPP", experts recommend that the concrete base, on which "Bikrost" will be laid, be thoroughly dried, heated with a burner and treated with a primer from "Technonikol". Such a procedure helps to significantly improve the adhesion characteristics to the base, especially if it is not possible to qualitatively remove moisture from a porous or cracked surface. Further, when surfacing the web, the primer will be compacted and fused with the Bikrost bitumen layer.

The material is sold in rolls, each weighing 45 kg. In one roll, the "Bikrost" canvas is rolled up, 15 m long and 1 m wide. On the outer surface of the roll, warning information and information about the batch and release date must be applied.

When laying the roofing, the edge of the web is turned away from the roll, the edge and base are heated to operating temperature and the material is slowly rolled in the required direction. The characteristics of the Bikrost bitumen sandwich allow heating only up to 80 ° C, at a higher temperature the bitumen will begin to flow and expose the fiberglass frame. In addition, in order to ensure good adhesion to the stone base, the heating must be carried out evenly, but quickly enough.

When arranging roofing coverings of a large area, it is more rational to install several rolls at the same time. This results in a dense coating with the best adhesion characteristics.

Rolled cloth "Bikrost" manufactured by "TechnoNIKOL" is a modern material used in roofing works. This product, due to its technical characteristics, significantly improves the quality of waterproofing and facilitates this time-consuming and messy process. Practical experience of use shows that the product, along with the advantages, has disadvantages that the consumer needs to be aware of.

Structural composition

The main purpose of the material is to create an absolute tightness of the coating. Since we are talking about a roof, this means a high level of water resistance of the canvas. This applies to all types of building materials. The product has a two-layer structure and resembles a sandwich.

The base is a synthetic polyester fiber or glass fabric, a viscous bitumen mixture or bitumen modified with polymers, applied on both sides under high pressure. Three letters in the classification terminology of the material give information about the composition of the canvas.

Reinforcing (main) layer or the first letter can be denoted by the symbol:

"X" (fiberglass);
"C" or "T" (fiberglass);
"E" (polyester fibers);
"O" (cardboard backing).

Surface coverage information is indicated by a second letter:

"K" (shale screening or granular rock);
"P" (polymer film);
"M" (mineral sand).

The third letter in the marking is the coating of the back of the material:

"P" (polymer film);
"M" (mineral mixture).

The material is produced in the form of a roll cloth with a width of 1 m and a length of 7 to 15 m. The weight of the package also depends on the footage. It can be 30-45 kg. The consumption of the canvas during use is calculated taking into account the overlap (by about 8 cm).

The material is in demand due to its widespread use. It can be used to cover the roof, including its sloped options. The brand's products are suitable for use as a vapor barrier and waterproofing, suitable for restoration and renovation of roofs. The material has a relatively affordable price, which is quite consistent with the declared qualities of the material.

Characteristics

The parameters of the material and its distinctive properties are confirmed by certificates and other documentation that must be viewed when choosing a product. The product is applicable for different types of roofing. It can be used on straight and flat surfaces, there are several basic characteristics.

It is worth noting the advantages of this material.

Plasticity and flexibility. This indicator is important, because at low temperatures, the canvas is difficult to bend and is prone to cracking. Brittleness is found at -15 degrees (this applies to the HSP model).
The material has good heat resistance parameters. These useful properties make it possible to avoid spreading of the web from the reinforcing coating at high temperatures.
Tensile strength. The reinforcing mesh can withstand up to 30 kg of tensile load, while the bitumen is not damaged.

In addition, the material is characterized by water absorption. During the day, it absorbs water in the amount of 1% of its own weight.
The high fire safety of "Bikrost" is due to its compliance with the flammability of B3. It belongs to the class of combustible materials G4.
Ease of installation, installation in a short time. Installation can be done within a few hours.

The main disadvantage is a short service life - about 5 years (with the exception of material based on fiberglass, which lasts from 7 to 10 years).
The builders note that the material is quite heavy, and this is an undoubted drawback in the conditions of work on the roof.
For the work process, you will need special construction tools and a gas burner, otherwise you can not hope for a high-quality result.

Features of different types

The two main types of Bikrost material have some differences. These are waterproofing sheets that are most in demand for roofing work.

"Bikrost K" - products used for the top layer of the roof. Its outer surface is made of coarse slate or sand, the thickness of the material is 3.7 mm.
"Bikrost P" - a distinctive feature of the product is a protective bottom layer in the form of a polymer film, the total thickness is 2.7 mm.

Other varieties are worth noting.

CCI - frame fiberglass, obtained by weaving glass threads and impregnated with a mixture of bitumen. It is considered the most durable. Above and below it has a protective polymer film. This coating can last up to 7 years.
HPP used for the bottom laying of a multi-layer roofing carpet. The base of the material is fiberglass, treated with a bitumen and polymer mixture, covered with polyethylene on all sides.
HKPis based on fiberglass. On the outside, it has shale dressing. There is a polymer on the inside. The canvas does not fade under the influence of the sun and is considered strong enough due to the protection with the use of granulate.

TCH- refers to especially durable varieties, the basis is fiberglass. The top side, in addition to bitumen, is covered with gray roofing granulate (shale grit). This type of soft roof is suitable for ballast and non-load-bearing flat roofs. This is the most expensive product, the cost of which is determined by high quality and reliability.
ECP - a plastic type of waterproofing sheet, successfully used for roofs with a slight slope.
EPP - material suitable for thermal insulation, covered with plastic film on both sides.

It is not at all necessary to make only one layer of waterproofing. With the help of two layers of "Bikrost" (HSP and HKP), superimposed one on top of the other, a higher quality of the coating is achieved, the service life is increased to 12 years.

Installation of waterproofing

You can lay waterproofing materials of this brand yourself. At the same time, it is desirable to have basic knowledge of the process and observe safety precautions. All work is carried out in special clothing and shoes.

For installation you will need:

gas stove;
propane cylinder;
special roofing knife;
bituminous primer;
rolling roller with metal needles;
hoses;
hook;
brush;
rolled cloth.

Preparation comes down to cleaning the surface from old coatings, fine debris, moisture and dust. It is necessary to align the plane as much as possible. For this, a solution of cement or bitumen mastic is used.

After that, a primer mixed with gasoline is applied with a brush or brush. Its layer must dry before further work.

The roll is rolled out at the place of fixation with a margin of 20 cm on both sides. The excess is cut off, the prepared sheet is folded again.
The work should be done together. Roll out from bottom to top using a hook. At this time, the second worker heats up the material and the roof, taking care not to destroy the bitumen layer.
This is followed by the connection of the material with the base, after which they pass along the edges with a roller, paying special attention to the seams.
After the lower part has dried, proceed to the front coating, using products with granulate to protect against external influences.
With a roof slope of more than 15%, the soft roof is fixed along the edge of the eaves, less than 15% - fixed perpendicularly and parallel.

You cannot walk on the coating until it is completely dry.

Bikrost roofing materials are widely demanded products. The waterproofing sheet of this brand is especially popular. This is a relatively affordable material, the cost of which depends on the strength characteristics.

For covering the roof of the garage with technonikol with your own hands, see the following video.

An integral part of the process of arranging the roof of any structure is its waterproofing. Moreover, the choice of this or that material directly depends on the type of roof. In this article we will talk about such a popular material as Bikrost - what it is, what are its varieties and technical characteristics. In addition, we will describe the sequence of work with this material, we will give several recommendations.

"Bikrost" - what is it

Roofing Bikrost is one of the affordable varieties of roll materials, which has a noticeably higher quality than, say, ordinary roofing material. The main purpose of such a roof is to protect residential or industrial buildings from moisture and damage to floors, load-bearing structures and other property. It should be noted that bikrost is most preferable in the case of flat or slightly sloping roofs.

You can name the following examples of the use of this material:

arrangement of the upper or lower layers of the roof;
providing waterproofing of load-bearing structures in large engineering structures - bridges, tunnels and others;
replacement of old roofing materials, the service life of which has expired;
installation on a hard sub-floor in rooms requiring additional waterproofing, such as basements or basements.

Bikrost roofing material consists of the following components:

plastic film and a layer of fine gravel;
oxidized modified bitumen layer;
fiberglass - cloth or canvas;
another layer of modified bitumen;
a layer of polyethylene film to protect against sticking of bikrost during transportation and storage.

Among the main advantages of the material are the following possibilities:

The working temperature range of the material is -30 ℃ to 50 ℃.
Bikrost can be laid at an air temperature of 0 ℃ (in more detail: "").
The structure of the material ensures its high mechanical strength.
Provides high-quality insulation and waterproofing.
The service life of the material is at least 10 years.
Bikrost can be used to repair damaged roofs by laying it on top of the old coating. In addition, it can also be used as a basic roofing material.
Installation is very quick and easy.
The material is available to most buyers due to its low cost and good quality.

Mounting method

By and large, no special skills are required to work with bikrost. However, you will still have to acquire a certain set of tools and monitor compliance with certain standards.

In order to cover the roof with bikrost, you need to complete a certain list of works.

At the initial stage, preliminary preparation of the roof should be performed. The old, worn-out waterproofing coating must be dismantled and the surface must be cleaned from dirt.

If the previously laid material is preserved in good condition, it can serve as a basis for laying bikrost. However, it will need to be prepared for additional treatment before further installation of new waterproofing.

The next step is the actual processing of the rough surface. In this case, there are a number of subtleties. In particular, if cracks are found on the old coating, and it has become permeable to moisture, it will need to be repaired. All cracks are poured with bitumen mastic, which is capable of plugging defects, restoring the material to its original properties. However, this method is applicable only in cases where the total area of \u200b\u200bdamage does not exceed 10% of the surface.

After the mastic has completely dried, the treated surface is covered with a layer of primer. It is needed for the subsequent adhesion of the bikrost to the old insulating material and to prevent the separation of the roof.

Now you can start working with bikrost. Since it is sold in rolls, it must be rolled out on a flat surface before installation and allowed to sit for a while to flatten. After that, the material is trimmed to fit the specified dimensions.

During installation, in order for the bikrost to adhere to the roof surface, it must be heated. To do this, you need a propane or butane gas burner.

Start work from the edge of the roof. After heating the end of the roll with a gas burner, it is pressed against the surface. Then the roll is gradually rolled out on the roof and warmed up. At the end, the laid bikrost is rolled with a heavy hand iron roller so that the material grasps well.

As soon as the laying of the first roll is completed, you need to immediately take on the next one. Installation of each next layer of bikrost is carried out with an overlap of 10-15 cm. Thus, complete tightness of the seams is achieved, and moisture does not enter the space between the rolls.

After installation, the tightness of the seams must be checked, since any pores and gaps will lead to a violation of the integrity of the coating.

Before starting work, the surface of the roof must be thoroughly cleaned of dirt and dust, and the imperfections and defects of the rough coating must be eliminated.
The installation of the bikrost must be carried out from the bottom up so that the water is gradually drained from the roof.
It is convenient to roll out and warm up the roll material using a hook without sharp edges.
For work at height, workers must be provided with safety belts.
Since the handling of gas burners can be hazardous to health, work should be done in special clothing and a respirator.

Varieties of "Bikrost"

Manufacturers make bikrost of two varieties - lining and roofing, therefore, they are marked with the letters "P" and "K".

For laying, Bikrost P is used as a waterproofing intermediate layer. It has a double-sided bitumen base, and is covered with a low-melting film on top.

But "Bikrost K" serves as a finishing waterproofing material for roofing. The lower part of such a coating consists of bitumen, and on top there is a fine and coarse-grained granite crumb.

Explanation of designations

There are a number of varieties of "Bikrost" roll material, therefore, to determine the composition, it is marked with a three-digit letter code.

Here is the decoding of the letter designations:

P - the presence of a polymer film.
K - coarse gravel chips.
M - mineral dressing with fine fraction.
C - the basis of the material is standard fiberglass.
T - frame fiberglass is used.
X - the base is made of fiberglass.
E - polyester nonwoven fabric at the base of the material.
О - the basis is specialized cardboard.

The greatest demand is for the brands KhPP, TKP, HKP, CCI; EKP bikrost and other products are also of very high quality, although they are bought somewhat less often. In addition to the composition, the marking indicates such characteristics of bikrost as weight in kg / m 2, as well as the color of mineral chips and technical specifications used in production. Note that the bikrost thickness will also depend on the component composition, which it is desirable to take into account when carrying out the work.

Material specifications

The technical characteristics of bikrost, depending on the brand of products, may differ slightly, since their component composition is also different.

Consider the main parameters of various grades of material:

Bikrost HPP - This is a material used mainly as a lining waterproofing. It is based on fiberglass, on which a layer of bitumen is applied on both sides. The upper part of the roll material is covered with a protective film that prevents the layers from sticking together. The characteristics of the bikrost HPP do not allow its use for any other purposes, since it does not have high mechanical strength.
Bikrost brand HKP is more durable, therefore such material is used as the main roof. In this case, fiberglass is also the basis. On the front side, a layer of coarse mineral chips is applied to the base, and a layer of oxidized bitumen is located below. A low-melting film protects the roll material from sticking.
TCH - This is a kind of bikrost, which contains fiberglass. The front part of the material is covered with a mixture of bitumen and gravel, and the back consists of a bituminous layer. Such bikrost has good mechanical strength and is mainly used for inverted roofs.
Bikrost CCI basically contains a frame fiberglass, which is covered with bituminous layers on both sides. Therefore, this type of material is used to perform lining waterproofing. This type of bikrost in combination with HKP and TKP brands shows itself well.
Bikrost SPP - This is the cheapest type of roll waterproofing. It consists of a base layer of standard glass cloth, which is covered with a mixture of bitumen with fine granite granules on one side and oxidized bitumen on the other.

Storage conditions

Please note that bikrost roll wrappers have a tendency to stick together. Therefore, it should be stored only in an upright position, without stacking several rolls on top of each other. If stored improperly, even protective films cannot prevent sticking.

In addition, bikrost should only be stored indoors, without access to direct sunlight and precipitation, at a temperature of at least -10 ℃.

Outcomes

Thus, due to the variety of types of bikrost, everyone will be able to choose the best option for themselves and enjoy a working protected roof for many years. At the same time, installation will not take much time and effort.

The classic bituminous roofing material, which was traditionally used for waterproofing roofs and external roofing, has been practically ousted from the market by modern materials based on modified bitumen. These include the rolled material Bikrost, which allows you to mount a reliable waterproofing pie on a flat roof and a roof with a low slope. Laying method - fusion.

Material features

Despite the fact that the affordable Bikrost is an economical option, it allows you to provide high quality waterproofing of the roof or other building structures. Depending on the type of material, it can be used as a lining or top layer of bituminous roofing cake.

Bikrost is based on a glass or polyester fiber material. A layer of modified bitumen with a filler is applied to the base on both sides - it is bitumen that is responsible for water and vapor impermeability. The material differs from roofing material in an increased amount of bitumen and binder.

The outer layer of the bituminous sheet, intended for the installation of the underlay, is a polymer film or fine-grained dressing. Bikrost for external roofing is supplied with an external protective layer of coarse-grained mineral chips.

Bikrost structure

Shale dressing protects the bitumen layer from mechanical damage and destruction under the influence of ultraviolet radiation. Modified bitumen is resistant to cracking at low temperatures, which prolongs the life of the roofing deck.

Application

Bikrost, the top layer of which is a coarse or fine-grained dressing, is designed to be used as a finishing layer of roofing carpet on a flat roof or roof with a low slope. The material successfully resists weathering and mechanical stress. But in regions with increased solar activity in hot weather, the canvas softens and can be damaged at high point mechanical loads.

The canvas with protective coatings made of polymer film is used as waterproofing and vapor barrier. During the installation process, the bottom layer is melted, due to which a tight fit and high adhesion of the elastic material to the prepared base is ensured. The absence of coarse-grained dressing at Bikrost, intended for arranging the lining carpet, contributes to the high-quality adhesion of the upper layer of the roofing cake to the lower one.

Film-coated bikrost is suitable for waterproofing walls and floors, foundations, basements, ceilings between floors, for creating vapor-tight barriers. With the help of this material, it is allowed to insulate water pipes, tunnels and other structures.

To weld the canvases, professionals use a propane torch; for self-assembly, they use a technical hairdryer or a blowtorch. In some cases, installation using bituminous mastic is allowed.

Fused fabric Bikrost

Bikrost is a modern build-up roofing material that is suitable for refurbishment (can be installed in one layer on an old waterproofing cake), for reconstruction or equipping a roof covering with a rigid base.

Types of Bikrost

The Bikrost marking indicates the type of base and the types of protective layers (respectively, upper and lower). The purpose of the material, the scope of its use depends on this.

The basis of the frame fiberglass is designated by the letter "T", from the fiberglass - "X", from the polyester fiber - "E". Frame fiberglass, in comparison with fiberglass, has a higher strength, including tearing. Cloths based on fiberglass and polyester are used for use under light loads.

Bikrost is produced in two grades - for the top layer of the roof (with coarse-grained dressing) and lining (with a protective layer of film on both sides). The letter "K" denotes a coarse-grained dressing made of granulate or shale, "P" - a protective polymer film that protects the roll material from sticking during storage.

TechnoNIKOL Bikrost HPP 1x15m - a budget material based on fiberglass, suitable for installation of underlayment on an unexploited roof, for waterproofing walls and floors in rooms, the horizontal surface of foundation foundations.

Bikrost EPP is distinguished by a higher tensile strength, the scope of use is the same as that of rolled bitumen cloth with the HPP marking.

TechnoNIKOL Bikrost CCI 1x15m - due to the frame made of fiberglass fabric, it is suitable for mounting a backing layer of load-bearing coatings, can be used to protect horizontal and vertical surfaces of foundation bases from moisture, mounted on roofs with a steep slope.

Bikrost TKP is an affordable material for laying the finishing layer of a roofing cake. Also suitable for waterproofing various building structures.

Bikrost EKP is more durable and elastic, suitable for installation on roofs with a slope, and successfully withstands operational loads.

Bikrost HKP is a roofing material designed for operation under high loads. Suitable for pitched roofs, for waterproofing vertical surfaces of structures.

Specifications

Bikrost has good performance properties:

100% vapor and waterproof;
preservation of elasticity at low temperatures;
resistance to deformation when heated up to + 80 ° С.

The strength of the material depends on the type of substrate:

for fiberglass - 300 N;
for polyester fiber - 350 N;
for frame fiberglass - 600 N.

The service life for HPP and HKP is 5 years, for EPP and EKP - 7 years, for CCI and TKP - up to 10 years.

Taking into account the strength parameter and other characteristics, Bikrost surpasses roofing material, while remaining in the niche of the most affordable materials, unlike many other roll bitumen coatings. According to SNiP 23-01, the material is suitable for use in any climatic region.

Table. Technical characteristics of Bikrost

Dimensions and weight

Standard roll material width is 1 meter. The length can be 10 meters (for Bikrost with a crumb top coating) or 15 meters (for a material with a film top coating). When calculating how much material is required to arrange the roofing cake, it should be borne in mind that the strips are installed with an overlap of about 10 cm.

Thickness:

HPP, EPP, CCI - 2.7 mm;
HKP, EKP, TKP - 3.7 mm.

Weight of 1 m² of sheet with film coating - 3 kg, weight of 1 m 2 of sheet with crumb coating - 4 kg. Respectively, the weight of the roll, taking into account the length, is:

45 kg for CCI, EPP and HPP;
60 kg for TKP, EKP and HKP.

GOST

Bikrost is a material of 5 fire hazard class, it is:

flammable (group B3 according to GOST 30402-96);
highly flammable (group G4, according to GOST 30244-94);
highly spreading flame (group RP3, according to GOST R 51032-97).

The production of the Bikrost material is regulated by GOST 12.1.005-88 and must meet the requirements of Sanitary Rules No. 1042-73, which were approved by the USSR Ministry of Health and relate to the organization of technical processes. The concentration of harmful substances in the air during the production of bitumen roll material should not exceed the permissible limits.

Fire hazard

Bikrost is a fire hazardous material. An open fire is used during the installation of waterproofing or roofing mat. Therefore, work with the deposited material requires compliance with all fire safety requirements.

Storage

In order to avoid sticking of the wraps to each other, the roll material may only be stored in an upright position, protected from rain and direct sunlight. The room must be dry. The storage temperature is not lower than -10 degrees, the distance to heating devices, heaters is not less than 1 meter.
