DBRED W

SINGLE-LAYER SOUND-IMPEDANCE PANEL FOR WALL ACOUSTIC INSULATION

DBRED W is a single-layer sound-impedance panel for wall acoustic insulation, made of SBR rubber granules bound with MDI resin and polyurethane granules. Its high mass (740 kg/m³) and elasticity block airborne noise inside double walls and partitions.

Two thicknesses: W10 (10 mm, 7.4 kg/m²) and W20 (20 mm, 14.8 kg/m²), placed in the cavity of masonry walls or in timber roof build-ups. In laboratory, a double hollow-brick wall with W10 in double layer reaches Rw 64 dB.

NOTE
