Due to the fact that the fibers in the material are located in a chaotic manner, as well as due to the presence of air between the fibers, the isvel provides a high degree of thermal insulation and sound insulation. A high degree of fire safety is ensured by non -combustibility of the material. The entire set of beneficial properties of Isovol is preserved even when heated to 750 degrees. Izovol slabs have high elasticity, therefore, even with prolonged exposure to the load, they easily restore their original form. The vapor permeability of the material provides free circulation of moisture in the walls, preventing the formation of mold.
