Siderise RH/RV cavity barrier system represent the default choice for market leading, high performance, ‘Rainscreen Cladding Cavity Barrier’ applications.
Used in the external envelope or fabric of buildings, they ensure the system will drain freely, whilst maintaining airflow and providing an effective hot smoke and fire seal.
Incorporates a continuous bonded intumescent strip to the leading edge and encapsulated in a weather-resistant polymer film. In the event of exposure to fire, this expands and fully seals the designed ventilation gap formed at the time of installation between the barrier and the rear of the cladding, in compliance with CWCT and NHBC guidance for air gaps up to 50mm.
