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
  • Reduces floor-to-floor sound transmission.
  • Suitable for remedial treatment after installation of fire stops.
  • Accommodates facade movement.
