SIDERISE CVB/C10 Acoustic Void Barrier for Curtain Walling
Acoustic void barrier for curtain walling.
Application
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.
Description
Siderise CVB/C10 consists of a thin, flexible polymeric mass barrier core offering 10 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:
- Acoustic upgrade for curtain walling.
- Polymeric barrier.
- Flexible – easily cut, shaped and installed.
- Offering 51dB+ (Rw)
- Firesafe Insulation
- Fire resistance up to 1 hour
- Independently tested
