DBRED ZERODB GIPS

LAMINATED ACOUSTIC PANEL FOR WALL ACOUSTIC INSULATION

DBRED ZERODB GIPS is a laminated acoustic panel: an SBR rubber layer bonded to a 15 mm (0.591 in) type A gypsum board. Rubber adds mass and damping, gypsum board gives a ready-to-finish surface – in one board and one installation step.

It is the quick way to soundproof an existing wall without demolition: a free-standing lining with ZERODB GIPS 150-10 on a 12 cm (4 3/4 in) hollow-brick wall improves insulation by 18 dB (Rw 63 dB) in 85 mm (3 3/8 in). In new drywall partitions with a double frame it reaches Rw 75 dB; as a suspended ceiling it improves impact sound insulation by 18 dB.

NOTE

+18 dB on existing walls
Rw up to 75 dB
