Modern non-combustible insulation: 6 criteria for choosing a material
Non-combustible insulation is well suited for premises where there is a high probability of fire. In the climate in which we live, the issues of thermal insulation and warming of premises will always be relevant. For this, manufacturers are developing a wide variety of types of insulation that can be found in stores. They are made of various materials and have distinctive properties. Each of them has its pros and cons. One of the main indicators of an insulating material is its flammability.
Heat-resistant insulation: types of material
Heat-resistant non-combustible heat-insulating materials have a wide range of applications. They are used in the installation of ceilings, walls, roofs, ventilation and pipelines. It is also not replaceable in the construction of baths and saunas. However, not all insulating materials can be applied equally to all objects. There are preferred application features.
Types of non-combustible heaters:
- Basalt mineral wool. Fire-resistant fibrous soundproof material, which is obtained by melting mixtures of metallurgical waste. It is not only incapable of burning, but also does not undergo any changes under the influence of high temperatures. Today, it is this material that is most actively used for insulating ceilings, houses, facades, and other building elements. However, when choosing, you should pay special attention to the cost of cotton wool - cheap varieties have lower fire safety indicators. This material is environmentally friendly and safe for health.
- Foamed glass. A material that consists of the smallest cells. It is made from glass breakage. The low flammability of the insulation allows it to be used on any operating units.
- Glass wool. This material also does not burn and at the same time has a reasonable price. It is also made from broken glass. However, it has disadvantages, which include the danger to humans if the production technology is not followed. However, cotton wool has strength, heat resistance and hygroscopicity, which are much higher than its basalt counterpart.
- Perlite. This material is widely used in construction. It has excellent "fluidity", perfectly fills the voids of the masonry. It is not subject to corrosion and decay, and cockroaches, ants, and other insects start up.
Heat-resistant insulation can be purchased at any hardware store
It should be noted that for each purpose of use, it is necessary to choose a certain non-combustible insulation. This also determines the form of release of this building material. In terms of shape and structure, it can be foil-clad material, backfill, blocks, cotton wool, mats, rolls, mats, plates, as well as liquid.
Refractory insulation: material oxygen index
The oxygen index of the insulation is the degree of fire safety of the material, showing the minimum amount of oxygen per unit volume of the insulation.
The oxygen index has several flammability thresholds:
- 40% - high level, composite polymers;
- 31% - cellular and fibrous and non-combustible insulation;
- 20% are building materials that burn well in the air.
When choosing a heater for your needs, first of all, you need to pay attention to this indicator.
Universal refractory insulation expanded clay: application
Expanded clay as a non-combustible heat insulator has a huge advantage over other materials, and it can be used in any construction work, including the installation of fire hazardous objects. It has long been widely used in the construction of factory furnaces. And only it was used before modern mineral wool insulation appeared on the market.
- It is used as an underlying base when constructing a blind area made of concrete;
- They are laid as an insulating layer for floors on the first floors of multi-storey buildings;
- When arranging attic floors;
Expanded clay refractory insulation is sold in bags
When erecting roofs on especially large construction sites, such as buildings of industrial workshops, supermarkets, social and cultural institutions, a layer of expanded clay is poured as a heater before arranging the screed and roof.
Rigid insulation for walls and ceilings
Each building material has its own pros and cons. But then what, and even non-combustible, to choose for the walls?
One of the most important characteristics of a heat-insulating material is an indicator of thermal conductivity. The lower it is, the better. It is for this factor that it is worth choosing an insulating wall covering in the first place. However, it must be remembered that the walls account for only 20% of the heat loss. In this regard, in order to achieve the desired effect, the rest of the house will have to be insulated as well.
Experts say that it is most effective to insulate a house from the outside. For this, it is important to know the material's ability to vapor permeability. It is also necessary to pay attention to how the material resists the effects of the environment. If you want to insulate the house from the inside, then you should pay attention to the eco-safety of the material, as well as the absence of toxic substances in its composition.
Non-combustible thermal insulation materials: the principle of choice
Considering that there are a large number of heat-resistant and insulating materials on the market, it is usually difficult for a person to navigate what kind of material is better to purchase for certain installation work. To make the right choice, you need to decide on the type of work and find out which heat-resistant insulation is suitable for it.
Price will be of great importance in making your choice. You should know that the quality of the material directly depends on the price and vice versa. The more requirements we meet the material, the more expensive it will cost.
With the help of non-combustible heat-insulating materials, you can insulate not only walls, but also pipes
Properties that a non-combustible material must meet:
- Heat resistance
- Heat resistance (high temperature indicator);
- Moisture resistance;
- Fire resistance;
- Vapor barrier;
- Waterproofing.
All these qualities must be present in the correct insulation, which does not require replacement in the near future and will give the desired effect.
Non-combustible insulation makes it possible not only to protect the microclimate of the house from heat exchange with cold outside air. It also provides him with safety as protection against fire and fire, the likelihood of which is minimized. Fire-resistant modern materials can be used in the construction of any building, be it industrial facilities or residential buildings.

Foil stitched basalt mat made of basalt wool
Foil stitched mats made of basalt wool are made of fiber without the use of an adhesive binder, which allows you to preserve the environmental friendliness and safety of the material:
- For the formation and retention of the fiber, the fabric is pierced with a heat-resistant thread, which does not violate the flexibility and pliability of the basalt mat.
- The foil in such mats acts as a vapor barrier, which allows them to be used for thermal insulation of cold pipelines and ventilation ducts.
Broached foil mats made of basalt material are available in various densities and thicknesses, which are selected based on the requirements for heat and fire protection.
BASALT FOILED BF
NON-FLAMMABLE BASALT FOILED HEAT INSULATING MATERIAL Manufacturer: TIZOL Plant
Foil basalt is an excellent heat insulator, provides a double effect of heat protection, prevents heat loss of the building due to vapor barrier and reflects heat energy into the room. It also has excellent sound absorption capacity, which allows it to be used as a sound insulator. The material is environmentally friendly, durable, does not rot, does not crumble, does not emit harmful substances, and is elastic. Foil-clad basalt is a highly effective sound-heat-vapor-waterproofing. Foil-clad basalt (hereinafter BF) glued with foil on one side does not have a binder, the formation of the material occurs due to the forces of natural adhesion of fibers to each other. Whereas traditional thermal insulation is formed by resin, which, upon gradual evaporation, releases toxic gases such as phenol, formaldehyde and many others. Insulation has the ability to reflect thermal (infrared) radiation, thereby preventing its direct loss to the environment. This reduces energy consumption for heating a room or building. When using insulation with two-sided foil for insulating the under-roof space, it is possible to reduce the overheating of the attic in the hot season (thermos effect), i.e. keeps warm in winter and cool in summer. BF does not shrink during operation and installation, and, therefore, there are no gaps between the heat-insulating material and the insulated surface. Easy to cut, elastic and, therefore, technologically advanced when performing installation work. Application temperature from -200 C to + 700 C. High resistance to aggressive environments. Thin, flexible, very durable, moisture resistant, reflects up to 97% of heat.
