Apart from its basic fire protection properties, the mcr Tecwool F spray system can also be used successfully as an acoustic (sound-absorbing) coating, capable of dissipating sound and limiting reflections of acoustic energy off the surfaces of the divisions to be protected. The indoor application of the mcr Tecwool F coating results in the absorption of sound waves, reduction of reverberation and significant improvement of acoustic comfort. The weighted sound absorption coefficient for a 50 mm coating is as much as 0.90 (class A).

The mcr Tecwool F coating is to be applied directly to the surface of ceilings and walls. The use a special unit for mechanical application of the coating makes its application on partitions of any shape possible. Application of the coating gives a grey dashed plaster surface.

The mcr Tecwool F acoustical coating is completely non-flammable. It has the highest reaction to fire class A1 as per EN 13501-1 to increase the fire resistance of structural parts of buildings.
The sound absorption of the mcr Tecwool F system has been tested in accordance with PN-EN ISO 354:2005.
