Acoustic cavity barrier treatment to improve sound insulation performance via curtain wall slab edge voids.
The SIDERISE CVB/C-10 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/C-10 into slab-edge details is often crucial for controlling floor-to-floor sound transmission.
SIDERISE CVB/C-10 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.
Note: This product was previously known as Lamaphon CVB series acoustic void barriers.
