The Siderise CVB/C10 is a stonewool acoustic cavity barrier incorporating a central polymeric mass barrier layer. It is designed for use as a mass line below horizontal firestopping in curtain walls.
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.
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.
Acoustic considerations
The fire stop between the floor slab and façade represents a point of significant potential weakness in vertical sound transmission between floors.
Our facades technical team can provide guidance around using this acoustic upgrade to meet the project acoustic performance requirements.
