STILLNESS III is a damping system and sound insulation board composed of anti-vibration and massive elements. We select inorganic materials with different densities and thicknesses to form a composite layer with the best properties of sound insulation and vibration damping in order to effectively insulate the medium-low and low frequencies of the sound transmission. The layers of each compound model are sandwiched and adhere under high pressure.

These composite vibration damping and sound insulation board are much more practical than the traditional layer-by-layer construction and provides an effective sound reduction rate of walls and ceilings in all types of applications, from the music business to the industrial markets.

This multi-layer structure is portable and simple to install by using screws or contact glue and it is easy to cut to adjust to the room dimensions.


Insulation enhancement:
Between 18 and 22 db depending on the constitution of the base of the wall or ceiling.
With screws or contact glue. Reduces sound transmission loss property.
B-s1,d0 (similar to M1).
Environmentally friendly material.
High-density board, paintable surface.
The fact that it uses layers of Type X FR Gypsumboard and cement fibre board, enables its usage in construction as a fire barrier.
Total thickness: 4,0 cm (1 4/7").
Suitable for usage in large areas of construction.
1 layer of (10mm | 2/5") Polyurethane - Floatsheet® INS, 1 layer of (16mm | 5/8") Type X FR Gypsumboard, 1 layer of (2mm | 0/1") Floatsheet® VIB, 1 layer of (12mm | 1/2") cement fibre board.
