Heat-insulating mats. Application of thermal insulation mats Installation on the roof of a large building

Mats are highly demanded products. This is due to the versatility that mats differ in and their excellent performance characteristics. This is a very effective thermal insulation.

Scope of heat-insulating mats

Thermal insulation mats are used in a wide variety of fields. Among them:

• construction of civil and industrial types, where mats are used;
• creation of internal sound and heat insulation of floors, walls, pipes, partitions frame type, tanks, boilers, chimneys;
• security fire protection objects where mats are used;
• thermal and sound insulation of thermal equipment, hardening and heating furnaces.

Properties of thermal insulation fiber

Mats of this type are also called foil mats. Their distinctive feature is a thinness of about 3 centimeters. A special foil type material is attached to the base of the product. It is intended to be located directly under the pipes, as a result of which the heat transfer of the warm floor increases.

Polystyrene mats have excellent technological characteristics. Among them:

• resistance to burning, characteristic of mats;
• excellent heat-insulating properties, which these mats possess;
• resistance to aggressive environmental influences, as well as various chemical compounds, which distinguishes this thermal insulation;
• resistance to vibrations, which distinguish mats.

All these features provided the material with a very wide scope of application. The use of heat-insulating mats is advisable in various areas of shipbuilding, thermal power engineering, aircraft engineering, oil and gas industry, etc. An additional advantage that distinguishes the mat is its perfect non-toxicity and environmental safety, which makes it possible to use this heat-insulating material even in educational and medical institutions.

Thermal insulation mats: advantages

Such thermal insulation mat Material, like mats made from basalt fiber, has many advantages. Among them it is worth noting:

• excellent ability to provide thermal and sound insulation;
• fire safety and fire resistance (this material belongs to the flammability class NG);
• resistance to the effects of microorganisms and rodents, the occurrence of decay;
• high parameters of vapor permeability, ensuring the preservation of the level of diffuse resistance of structures;
• excellent hygroscopicity;
• availability of a wide range of standard sizes.

• building thermal insulation, insulating floors, walls, ceilings, partitions of various building structures, tanks and boilers;
• thermal insulation intended for ships;
• insulation in industrial equipment and units;
• thermal insulation of boiler room equipment.

Mats can be various types and species that differ in the composition used rocks. They are divided (depending on indicators such as fiber thickness) into coarse, thick, thick, super-thin, ultra-thin and micro-thin. In order to obtain material for mats, blowing heads of different shapes are used in production, as well as various types of spray devices. In our company you can purchase various types of mats at an affordable cost. Our mats are different high quality and reasonable price. We are glad to mutually beneficial cooperation!

Thermal insulation mats are a modern and effective solution for reducing the energy consumption of equipment with heating elements, as well as for the safe operation of personnel or for the premises where it operates.

Benefits of use

The use of these products is guaranteed to reduce heat loss and the intensity of its penetration by approximately 30%.

This provides not only reliable protection against excessive thermal radiation, but also from touching the hot parts of heating and process equipment.

Manufacturers

Among the manufacturers of stitched mats in terms of quality and cost, the following stand out:

• "Rockwool";
• "Technonikol";
• "Isover";
• "Izorok".

Applied filler

Thermal insulation mat is produced using different material. It can be basalt fiber and mineral wool. Ceramic fiber is also used.

They are distinguished by improved thermophysical properties, increased thermal stability, the level of which is much higher than that of other insulating materials.

Products made of ceramic fiber have gained great popularity among builders, they are widely used for insulation of pipelines, thermal insulation of exhaust gas pipes, lining of various furnaces, fire extinguishing systems.

In addition, the heat-insulating mat is used as a raw material for the manufacture of modular monoblocks.

Fiber fillers

Also, stitched mats made of glass and basalt fibers are in high demand among buyers. Previously, fiberglass was widely used for winding pipelines of heating mains (it is still used for this purpose). Modern technologies made it non-thorny, which made it possible to use it for many other purposes.

Mineral wool is called basalt fiber, which is also used for thermal insulation. The commodity form of this heat insulator is a mat or a roll.

These materials differ significantly in density, and their heat-conducting characteristics depend on the level of density and thickness.

Thickness and density are determined by the purpose of the heat-insulating mat. Sewing mats are equipped with seams made of nylon or glass threads, twine made of bast fibers.

Other classification

In addition to the filler, these products are also divided according to design features, so there are stitched mats of the following types:

• on a metal mesh;
• without lining;
• on fabric or fiberglass;
• on polyethylene film.

Advantages and distinctive features

This is in particular:

• significant reduction in electricity costs for heating;
• the absence of any harmful fumes during operation;
• long-term preservation of characteristics even at elevated temperatures;
• a significant reduction in the time for heating a room or equipment.

An important property of such mats is their complete immunity to fire. Both types of filler are non-flammable and non-flammable. They are not subject to decay, and with the organization of a good hydro- and vapor barrier layer, they will last for many years. Pierced plates are environmentally friendly, do not pose a threat to health, human life, and also do not negatively affect environment. They can be plastered, clad or painted.

Their main specifications

The technical characteristics of such a heater are as follows:

• high temperature resistance up to 500°C of the outer shell made of glass wool;
• the standard thickness of the fiberglass filler is 18 mm;
• equipped with special springs and mechanical clamps made of stainless steel;
• the possibility of equipping products with other types of clamps.

Purpose

Basically, heat-insulating mats, regardless of the material of manufacture, are used for roof insulation. There are mats designed for upholstery, but they are much denser than those used for roofs, and they are made only from basalt fiber.

Also, mineral wool insulation is widely used for insulation of ceilings, in particular suspended ones. Unlike basalt fiber, glass wool is much thicker.

Stitched mats made of this material are often used for arranging roofs of large premises - for example, shopping centers.

Other applications

In addition to the construction or arrangement of buildings and structures, heat-insulating mats made of glass and mineral wool are widely used for insulation:

• extruders and material cylinders of injection molding machines;
• flanges and valves;
• high-temperature parts of injection units;
• burners, furnaces, containers that heat up to very high temperatures.

Installation

When insulating roofs, the internal bearing basis of which are rafters (massive wooden beams), a heat-insulating mat is laid precisely between them. The choice of one or another insulation for arranging the roof depends on the pitch of the rafters, the distance from one beam to another.

The basalt fiber thermal insulation mat is laid directly between the rafters, its elasticity is sufficient to be firmly held between these roof elements. But to ensure greater reliability and durability, they can be sheathed from the inside with plasterboard or plywood.

Steam and waterproofing

When insulating the roof, one should not forget about vapor and waterproofing on both sides of the heat-insulating layer. Since all living things produce steam, there is a lot of it under the roof, because, being lighter than air, it rises. And this will lead to the accumulation of moisture in the basalt fiber, and it will lose its useful properties.

Therefore, it is necessary to ensure its protection from steam and moisture by laying an external protective layer - a film (vapor barrier). It can be easily attached from the outside with a construction stapler.

From the outside of the heat insulator, a hydrobarrier is equipped. Its purpose is to prevent moisture from penetrating into the fiber from the side of the roof, if it suddenly leaks. A waterproofing film is applied to the crate stuffed onto the rafters. Unlike basalt fiber, fiberglass is more often used to insulate partitions and interior walls.

In office premises, which often have plasterboard partitions, insulation is placed between them. This reduces heat loss and reduces the cost of space heating.

Installation on the roof of a large building

When arranging the roof of large buildings, mats are stacked in a checkerboard pattern in two layers. The first layer is lower - the filler of mats in it has a lower density. The second has a more rigid filler, which allows you to walk on it after arranging the roof. After installing the heat-insulating layer, roofing material is laid on top of the mats.

Wall mounting

It happens that basalt fiber slabs are used to insulate the wall outside the building. After their installation, it is necessary to equip a ventilated facade. Installation of mats should not be carried out during rain or in conditions of high humidity.

For arrangement false ceiling due to the severity of basalt slabs, it is undesirable to use, but if they are fixed on concrete floors and subsequently plastered, you will get a very reliable and durable insulation. The room will become much warmer and quieter, as the material also acts as a sound insulator.

Surface specific power of heaters

When choosing a heating device, it is important to consider the effectiveness of heaters. Good thermal insulation not only keeps heat in the room and reduces electricity bills, but also allows the use of less powerful heaters.

When choosing a heating device, it is important to take into account such an indicator as specific surface power - it is different for different devices. So, for a ceramic heater, this figure is 1.0 W / cm2, micanite - 0.5 W / cm2.

Basalt fiber embroidered mats are produced from various types of inorganic slags, which are obtained as a by-product in the blast-furnace industry. They are sold in rolls which, when unfolded, form a wide rectangular canvas. Basalt mats are used to provide thermal insulation of civil and industrial buildings and structures during construction work.

Advantages of basalt mats:

• reliable thermal insulation in a wide temperature range (from -180°С to +700°С);
• high resistance to fire - even at temperatures above 1000 ° C, only sintering of the material occurs;
• excellent property - damping of sound waves due to maximum porosity;
• the material is inert with respect to various chemically active substances: solvents, acids and alkalis;
• not subject to rotting, as well as to the influence of mold fungi and other microorganisms;
• the ability to absorb many types of radiation, which allows the use of mats at nuclear and thermal power plants.

Mineral wool is produced in the most different options because it has a wide range of applications. One of its forms are stitched soft mats. They are made from interwoven thin basalt fibers, which are fastened together not with synthetic resins, but with nylon, fiberglass or bast threads.

Modern heat-insulating stitched mats are manufactured in accordance with GOST 21880-2011, although different manufacturers may develop their own specifications. In fact, we are talking about really safe basalt insulation, in which there are no formaldehydes, phenols and other toxic substances.

The absence of thermoplastic bonds may impair the aesthetics and workability of the boards, but it effectively solves other problems. Light mineral wool performs the functions of thermal insulation better, but due to the hard cord of the firmware, it retains a constant volume. The only drawback of such mats was high hygroscopicity. That is why, on the basis of the current GOST, separate specifications were developed that allow impregnation of heaters with water-repellent compounds.

Types and features of mats

Stitched mats have standard basalt wool thickness options from 40 to 200 mm, but may differ in size from traditional slabs. Their length ranges from 1-5 m, width - 0.5-2.5 m. But the main classification of mineral wool products is tied to their density. In accordance with it, there are three types of thermal insulation:

1. M-75 - mineral mats with a specific gravity of up to 85 kg / m3 have a fairly high thermal conductivity of 0.046 W / m ° C. Other characteristics are also not impressive: compressibility is about 55%, tear resistance is the lowest in the group and in our review (80 N).
2. M-100 - have a density of 90-100 kg / m3 and thermal conductivity R \u003d 0.04 W / m ° C. The compressibility of the plates is 36%, they withstand 100 N at break. However, the difference in price between them and MP-75 is small.
3. M-125 - dense stitched mats (110-135 kg / m3) with a conductivity coefficient of about 0.044 W / m ° C. Breaking load resistance - up to 120 N.

Also today you can buy plates of lightweight M-35 and M-50 series, but these brands are not fixed in GOST.

The main difference between stitched products and other heaters is high temperature resistance. The absence of consumable bonds makes the mats completely non-combustible and allows them to withstand heating up to +800..+1200 °C, while conventional heat-insulating boards retain their shape only at +600°C. This also led to a low resistance to loads - the compressibility of soft mats according to technical description often approaching 40%, that is, the effective thickness of the insulating layer under pressure can be violated. But without external influence, basalt wool retains its shape well and does not shrink - the stiffness of the fibers is enough for this.

Heat-insulating mats can come with facings of different materials:

• Metal mesh (MC brand). For example, the TechnoNIKOL company uses different types wires: black, galvanized or galvanized.
• Fiberglass (ST or M3) - reduces the heat resistance of mats up to +450 ° C, but according to reviews, it facilitates installation.
• Roofing or corrugated cardboard (M4) - with a similar lining, mineral wool is not used at temperatures above +80 ° C, and it is difficult to buy such thermal insulation today.
• Paper (M5). This is also the designation of mats laminated with a vapor barrier PET film. Their installation is allowed only on bases that do not heat up above +60 °C.
• Aluminum foil - this product is most in demand today due to the vapor barrier of the coating, but it also has a rather high cost. But combined thermal insulation can be freely purchased by finding suitable option in the assortment of Rockwool, Paroc or TechnoNIKOL.

If laminating is performed on only one side, the stitched mats are marked M2-1, on both sides - respectively M2-2. The absence of additional designations, the letters M1 or MP indicate that the insulation comes without lining.

Application

Stitched mats are considered independent view technical thermal insulation and are used to protect communications and equipment (including high-temperature equipment), as well as in the construction of transport. But in everyday life they can often be found in unloaded structures:

• In ceilings.
• In internal partitions (if these are sufficiently dense pierced heat-insulating plates).
• When insulating smoke, water, heating pipes and ventilation ducts.

But do not forget that basalt insulation in conditions of a large temperature difference or used outdoors itself needs additional waterproofing. Therefore, it is used in tandem with light-resistant film materials with good vapor permeability.

Stitched mineral wool mats without facings are suitable only for thermal insulation for pipes - they are no longer suitable for anything, since their performance characteristics are rather weak. But the presence of the same metal mesh significantly expands the scope of combined insulation. Here it becomes possible styling in vertical structures and even use in ventilated facade systems (provided that the basalt wool is covered with a windproof membrane that prevents the fibers from blowing out).

Mineral wool mats - perfect solution and for insulation wooden buildings where the same "breathable" materials are needed. Only basalt thermal insulation provides normal moisture exchange for log cabins and timber frames, which guarantees their durability, prevents warping and decay of the forest. With its help, fire-prevention cuts are also created in walls, openings, in places where hot chimneys pass through floors and roofs.

And, of course, not a single construction of a bath or sauna can do without mineral mats. At fire hazardous objects, it is necessary to use only non-combustible heat-insulating boards that retain their shape and thickness even under the influence of high temperatures.

Price

Mineral wool is a thermal insulation made of stone, for example, basalt (TechnoNIKOL). There is a lot of air in its structure - at least 90%, due to which it has a low coefficient of thermal conductivity. Mineral wool is produced in the form of slabs, ordinary rolls and stitched mats without lining or with it. That is, one or two sides of the thermal insulation can be covered with foil, fiberglass, glass mesh, metal mesh, paper or other material. The mat is stitched through longitudinally or across with a thin wire, strong nylon or glass thread. Thanks to this method of manufacturing pierced heat-insulating boards, the amount of organic binder introduced is reduced. In addition, because of this, physical and mechanical characteristics increase.

The mats are produced only stitched and depending on the lining material the degree of their possible temperature load changes. They are also produced in various lengths from 1 to 6 m with a width of 50, 60 or 100 cm, the latter option is most often used. The thickness of the mineral wool mat can be from 20 to 120 mm depending on the application. An important feature of such thermal insulation is its increased resistance to fire. For a long time from half an hour, it protects structures from damage, and also does not allow the fire to spread further. The maximum possible heating temperature can reach +750°C (sometimes even up to +1100°C), as the stitched mats are made from mineral wool. Due to this, judging by the reviews of manufacturers and specialists, the time for the evacuation of people and equipment from the building is significantly increased.

Since the mats are stitched, they have good resilience and compressibility. As a result, the stitched heat-insulating plates of TechnoNIKOL or another brand fit perfectly to almost any type of base and structure. At the same time, they have a small weight, due to which significant pressure is not created on the insulated object. The dense structure allows to withstand mechanical loads.

Review positive qualities mineral mat:

1. low coefficient of thermal conductivity - 0.03-0.04 W / (m K), due to which heat losses can be reduced by 42%;

2. non-flammable material with a small amount of smoke emitted;

3. excellent soundproof performance;

4. environmentally friendly and safe;

5. resistant to high temperatures and various acids, oils, alkalis;

6. weak ability to absorb water and vapor permeability;

7. not a habitat for rodents and does not support the growth of mold and fungi;

8. long service life - 50 years;

9. does not lose its structure even under the constant influence of vibration;

10. does not rot and is not afraid of corrosion;

11.Easy installation and convenient transportation.

The following types of pierced rolled thermal insulation are produced:

• M1 or MP - without lining;
• M2 or MS - with a metal mesh;
• M3 or ST - with fiberglass.

Mats marked M1 and M2 withstand temperatures up to +750°C, and M3 - no more than +450°C. The cost at which you can buy them is significantly affected by the lining material.

Application area

Due to its heat-insulating and fire-resistant characteristics, pierced insulation is used in private and industrial construction (automotive and aircraft construction). Also in the food industry, for laying on wavy, cylindrical, rounded surfaces, such as pipes, air ducts, steam lines, electrostatic precipitators and much more. Turbines, boilers, dryers, steam generators, cooling chambers are trimmed with pierced mineral wool mats without lining and with it in order to reduce noise and heat loss. Often they are mounted in ventilation systems. In addition, basalt pierced thermal insulation is used to protect various equipment (boilers), tanks, vehicles.

In the construction of buildings with a small number of floors, it is used in the construction of frame partitions, attics, attics, walls, baths or saunas. In addition, stitched mats are used as a middle layer in the ceilings between floors and in cladding areas.

Price

Prices for rolled stitched thermal insulation depend on the brand, thickness, density, as well as the presence of a lining. Price table at which you can buy heat-insulating stitched mats:

It is important to follow the manufacturer's instructions for storage and transportation. Folding stitched mats is allowed only in covered areas or under a canopy, the main thing is that they are not exposed to atmospheric precipitation. The height of a stack of mineral wool stitched insulation should not be more than 3 m. Rolled thermal insulation of this type is used only as a non-loaded material. For construction, you should purchase products stitched longitudinally. All installation work can be done by hand.
