Siderise CVB/C10 Acoustic Cavity Barrier for Curtain Walling
Verified by manufacturer 7 days ago
Acoustic cavity barrier treatment to improve sound insulation performance via curtain wall slab edge voids.
Application
The Siderise CVB/C10 is a stonewool cavity barrier incorporating a central polymeric mass barrier layer. It is designed for use as a mass line below horizontal firestopping in curtain walls to improve acoustic performance via the critical slab edge void.
Using this acoustic upgrade can offer a significant improvement to the acoustic performance of the firestop. Incorporating mass barriers such as the Siderise CVB/C10 into slab-edge details is often crucial for controlling floor-to-floor sound transmission.
Siderise CVB/C10 is quick and easily to install, and is suitable for use in all curtain walls. The product is thin and flexible, and is designed to accommodate façade movement, unlike traditional mass-barrier materials such as steel or plasterboard.
Description
Siderise CVB/C10 consists of a thin, flexible polymeric mass barrier core offering 10.5 kg/m² of surface mass to resist sound transmission. This is surrounded by high-density stonewool on both sides. The faces are reinforced with aluminium foil. The entire product is 55 mm thick.
Features and benefits:
- Reduces floor-to-floor sound transmission.
- Ideal for remedial treatment after installation of fire stops.
- Accommodates façade movement.
- Quick and easy to install.
- Offering 32 dB(Rw); (mass barrier layer only).
