Siderise AVC Acoustic Void Closure 1240mm x 2040mm x 30mm

The Siderise AVC Void Closure is a laminated composite acoustic seal combining an outer resilient foam layer with an inner flexible mass barrier membrane.

Designed for straightforward compression fitting into apertures, gaps, and voids, it provides an effective acoustic seal to reduce sound transmission.

Ideal for construction and building applications, the AVC Void Closure helps maintain airtight seals while enhancing overall noise control.

Features Effective acoustic seal – Laminated foam and mass barrier combination reduces sound transmission Fire safety – Classified B-s1, d0 to EN 13501-1 Lightweight & practical – Surface weight of 12 kg/m² for easy handling and installation Easy to install – Compression fit design for gaps, apertures, and voids Construction-ready – Ideal for building applications requiring reliable noise control Sheet form for site cutting – For small gaps, the closures are simply friction fitted.

For large gaps, the closures can be securely retained top and bottom by metal angle sections.
