ACOUSTIC ROOF SLAB 571 & 572 is designed for use in double skinned metal roofing systems to enhance sound absorption performance.
Acoustic Roof Slab 571 & 572 consists of a black or white tissue faced rock fibre slab which is manufactured in a variety of densities.
Works in two ways to reduce noise, either by absorption of sound at the surface or inhibiting its transmission. Acoustic Roof Slab 571 & 572 is an ideal sound absorber. The absorption coefficient achieved will vary according to thickness, density of slab and application.
Can be cut to size (e.g. 30mm x 1200mm x 193mm) for positioning within the profile of the perforated inner sheet or supplied in standard 1200mm x 600mm slabs for overlaying the perforated inner sheet, according to manufacturer’s specification.
The tissue facing helps to avoid the slab edges from showing as shadows through the perforated inner sheet and assists in preventing fibre migration.
• Excellent sound absorption
• Tissue faced for visual effect
• Suits all manufacturers’ systems
• Easy to install
Acoustic Roof Slab (571 & 572) is supplied in thicknesses and densities determined by the roofing manufacturer’s acoustic performance requirements.
