Flexible Foiled Rainscreen Cavity Barrier RS/WB Non Venitlated 200mm x 1m

Flexible foiled cavity barrier consisting of intumescent coated cloth on a galvanised mesh. Made with or without ventilation and drainage holes, used both vertically and horizontally.

  • RS/WB/B – non-ventilated
  • RS/VWB/B – ventilated with ventilation holes, either, 1, 2, or 3 holes according to the width of the barrier
  • RS/WB/CV/B – with an intumescent strip on the face to allow the barrier to have airflow opening up to 100mm. The intumescent strip expands in a fire, filling the opening.
Specify the overall cavity size and required ventilation gap when ordering.

Cavity Barriers are pieces of fire-stopping material. They fit within the cavity of a building at each floor horizontally and party wall in a verticle position. The material provides compartmentation. Both the flames and heat cannot be transferred to other compartmental areas. Throughout the life of the building, the Cavity Barrier will remain fixed in place. In the event of a fire, the intumescent material expands and seals off the gaps. Additionally, the horizontal barriers allow for a ventilation gap within the cavity. Subsequently closing when the intumescent expands.
