Autex Soffit & Slab Liner (ASL) – Group 1 Insulation
GreenStuf® Autex Soffit and Slab Liner (ASL) has been engineered as a thermal and acoustic lining for masonry soffit type applications. ASL is designed to improve the thermal and energy efficiency of the building envelope. GreenStuf® ASL Group 1 Insulation will also assist in the control of reverberation levels and noise spill. GreenStuf® ASL Group 1 Insulation is designed to be installed to the underside of masonry and metal pan floors and ceilings.
Autex ASL Group 1 Insulation – Applications
GreenStuf ASL is designed to be installed to the underside of masonry and metal pan floors and ceilings to improve thermal performance and energy effiiency of the building. GreenStuf ASL Group 1 Insulation will help lower noise levels by controlling reverberation times in enclosed spaces and reduce noise spill to external areas.To ensure building code compliance architects and building designers are advised to consult an engineer or the relevant Australian Standards before specifying thermal and acoustic insulation products.
