Fire-fighting properties

Mineral wool, based on basalt fiber VATTARUS refers to a group of combustibility NG - non-combustible materials. This is due to the fact that for mineral wool production using VATTARUS rock basalt group. The melting temperature of basaltic rocks is 1500 ° C, as a result of the sintering temperature mineral wool fibers exceeds 1000 ° C. This fact allows us to contain the spread of fire in the building and destruction of its supporting structures.

Insulating properties

Mineral wool, based on basalt fiber, VATTARUS provides a low coefficient of thermal conductivity. The main role in heat insulation mineral wool insulation VATTARUS play the number and size of pores, the number of interlacing fibers that provides air convection, which transfers heat between the pores. Insulating properties of wool are based on low thermal conductivity of air.

Sound-absorbing properties

Regardless of the origin of the noise causes a negative impact on the human body. Sound-absorbing properties of the material - is its ability to prevent the spread of sound, relaxing sound pressure. Due to its fibrous structure and the presence of air voids, mineral wool, based on basalt fiber has excellent sound absorption VATTARUS and minimizes the acoustic vibrations.

Chemical Resistance

Basalt fiber resists harmful organic substances, because in the rock, there are no processes of rot, decay and mold. VATTARUS mineral wool insulation has a high chemical resistance to solvents, weak acid and alkaline environments, and therefore allowed to use a heater in a corrosive environment.


Basalt fiber has the highest resistance to water compared with other mineral fibers, and the special hydrophobic additives reduce the coefficient of water absorption insulation up to 1-1,5%. Mineral wool, based on basalt fiber, VATTARUS has excellent hydrophobic properties, which favorably affect the low thermal conductivity insulation.

Water vapor permeability

Steam and condensate are the main enemies of fibrous insulation materials, destroying the fiber structure and make it brittle. High water vapor permeability of mineral wool on the basis of basalt fibers VATTARUS is achieved by having the structure of air voids. With proper application of mineral wool insulation in the structure of the building envelope, prevents the accumulation of moisture in the insulation and ventilation is provided by the building.

Environmentally friendly

Mineral wool VATTARUS allows repeatedly to reduce the negative impact of humans on the environment, which is mainly due to savings in energy consumed by man for nearly all aspects of his life. Scientific method has been found that buildings constructed with the use of thermal insulation materials, save up to 60% of the energy and production costs significantly lower future savings.


Due on - rock basalt group - VATTARUS insulating material has a unique strength and durability of stone with a high insulation characteristics. As world experience shows the use of mineral wool insulation, the life of the product at the correct operating in compliance with all recommendations for the application of not less than 50 years.


As lower heat insulation layer for flat roofs with design loads not exceeding 25 kPa. Recommended with VATTA RUS ROOF V as an upper layer. As thermal insulation layer in a single-layer flat roofings with design loads not exceeding 25 kPa plus cement & sand underlayer.
