Knauf-Cubord is a great solution to increase the level of sound insulation of gypsum partitions, partitions of aerated concrete and foam concrete with thickness of 80-100mm. Also suitable for interroom walls of the same material.
Working principle: thin walls have the lack of growth of sound insulation in the frequency range of 200-600 Hz. Panel Knauf-Cubord reduce the resonant propagation of sound in this range when mounted with 1 side.
Consists of a weighted sheet of gypsum Board with a density of 1100 kg/m3 and glued to it layered fleece.
Sheet size: 1500х1200 mm.
Material thickness: 20 mm (16 mm of gypsum Board and 4 mm fleece).
Index additional sound insulation: Rw=5-9 dB.
