DBRED W

SINGLE-LAYER SOUND-INSULATING PANEL FOR WALL ACOUSTIC INSULATION

DBRED W is a single-layer sound-insulating panel for wall acoustic insulation, made of SBR rubber granules bound with MDI resin and polyurethane granules. Its high density (46.2 lb/ft³ (740 kg/m³)) and elasticity block airborne noise inside double walls and partitions.

Two thicknesses: W10 (13/32 in (10 mm), 1.5 lb/ft² (7.4 kg/m²)) and W20 (13/16 in (20 mm), 3 lb/ft² (14.8 kg/m²)), placed in the cavity of masonry walls or in timber roof build-ups. In laboratory testing, a double hollow-brick wall with two layers of W10 reaches Rw 64 dB.

NOTE

High-mass rubber panel
Rw up to 64 dB in a double wall
