The mat is made from stone basalt thin and superthin cotton wool by density from 35-do80 in kg/m ³. On the one hand the mat becomes covered with aluminum foil 30 microns thick and a grid from the galvanized steel wire diameter 0,4mm (facing by a corrosion-proof grid is possible). Mats are stitched by a corrosion-proof wire and zakashirovana can be aluminum foil 30 microns thick

Mats proshivny are made on the basis of thin and superthin basalt fiber and the equipment is stitched by a glass or basalt roving special.
In comparison with mats and canvases from basalt superthin fiber import glass wool, as well as domestic glass wool and slag wool widespread today have essential shortcomings. In these materials various pitches posing potential threat for human health are applied to a linking of fiber glasses (and shlakovolokon) if their concentration in air exceeds maximum concentration limit. Unlike glass wool and slag wool high elasticity and big length of basalt superthin fibers provide their strong interlacing. Basalt superthin fibers are fastened with each other with forces of natural coupling.
The important characteristic of any heat-insulating material is its heat conductivity. The best heat insulator in the nature is air. Thanks to absence binding, the low density and open porosity the layer of basalt superthin fibers is well saturated with air and the bigger amount of air, than glass wool and slag wool holds in product volume. Short fibers of glass wool and slag wool do their structure to more dense that, as well as binding, interferes with penetration of air into a layer of material and its deduction.
Heat conductivity of products makes from 0,033 W of BTV and BSTV of different types and brands / mk to 0,038 W / mk (at 25 °C) unlike 0,044 W / mk for mines slag wool.
The comparative characteristic of various heaters applied in construction shows that effective isolation at an external temperature - 38 °C is provided with a layer of basalt superthin fiber of 35 mm, glass wool of 90 mm, a gas concrete of 210 mm, and a bricklaying of 770 mm.
Thermal isolation of units and the equipment promotes economy of a large amount of fuel. So, application of 1 m 2 bazaltovoloknisty heat-insulating materials 35 mm thick allows to save 1 t of conditional fuel a year. Summing up the result of the aforesaid, we will draw a conclusion: using materials from BSTV possessing so valuable properties as thermal insulation, the consumer most effectively resolves an energy saving issue in any place of its application. Canvases, mats from BSTV guarantee reliable thermal insulation, ecological and fire safety, security against noise as any other heat-insulating material.
Mats proshivny on the basis of basalt superthin fiber are intended for extralight, effective heat insulation of the industrial equipment, air ducts of hot air, external and internal steam lines, coppers, boilers, heat exchangers, pipelines, the warmed liquids or gases at high-temperature processes, Is used for isolation of flues, chimneys, as fire protection of building constructions, at thermal insulation on nuclear and thermal power plants as does not accumulate radiation.
