Application

Designed to effectively close small apertures and voids encountered in a wide range of building conditions.

Depending on the sound insulation performance required, they may be employed singularly or in pairs (fitted either 'back to back' or commonly to each side of a central mineral fibre resilient infill).

Examples of use include, top of wall junctions, gaps around service ducts, perimeter heater cases, continuous lighting trays and air diffusers.

Description

Siderise AVC acoustic void closures are a laminated composite combining outer resilient foam layers with an inner flexible mass barrier membrane. The closures can be supplied cut to the final aperture shape but are also available in strip form (for linear gaps) or sheet form for site cutting.

They are intended to be compression fitted into an aperture to form an acoustic seal. Large deflections can be securely retained top and bottom by metal angle sections.
