Reduces direct airborne sound transmission and unwanted flanking noise, in order to help where necessary to comply with Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015 (on the constructions illustrated).
Isowave performs under the following classifications:
Fire protection 30 minutes (for a single layer)
BS476-7 Fire Propagation Index <12 BS 476-6 Surface Spread of Flame Class 1 Building Regulations Paragraph A13 (b) Class O
Isowave 23 consists of a 10mm Isowave acoustic foam measured to BS 4443 and BS EN ISO 845:2009 bonded to 12.5mm high density, square edged fibre-reinforced gypsum board. Isowave 23 system incorporates acoustic foam which is semi rigid and is an excellent absorber with high damping characteristics when bonded to an acoustically reflective stiff surface. Isowave foam is manufactured using water as a blowing agent and is free of CFCs, HFCs or HCFCs. Isowave 23 acoustic ceiling system complies with requirements of EU Regulation No 2037/2000 for ozone depletion and offers good thermal properties.
The Isowave 23 acoustic wall system is for the treatment of excessive flanking sound that bypasses a separating floor via lightweight structural walls. The Isowave 23 acoustic wall system is used to enhance a wall that is found to underperform or to provide a high performance wall commonly used in home cinemas/studios.
