A range of flexible, moisture-resistant cavity barriers for providing an effective fire and smoke seal in the cavity between brick or block walls and rainscreen cladding.
RS/WB FLEXIBLE FOILED RAINSCREEN CAVITY BARRIERS: A barrier consisting of an intumescent strip faced with high tensile foil, which expands to create a powerful fire and smoke seal. Available in a ventilated form with two rows of holes (RS/VWB), or faced with a cavity strip barrier (RS/WB/CV) which will expand outwards in a fire to seal off larger cavities. Can be fitted with either washer fixings or bracket fixings, depending on the width of the cavity.
RSF AND RSM FLEXIBLE SPONGE RAINSCREEN CAVITY BARRIERS: Intumescent impregnated sponge barriers with fire and smoke stopping capabilities, clad in either moisture resistant foil (RSF) or a durable, intumescent-coated material (RSM). Available in a ventilated form fitted with one or two rows of holes (RSF/A and RSM/A), both of which are fitted a rubberised intumescent strip. Also available with a thick, front-facing strip of intumescent which will expand outwards in a fire (RSF/I and RSM/I). All are fitted with bracket fixings.
- Barriers have a slim profile without compromising fire rating – will still protect for up to 2 hours
- Non-fibrous, dust-free and easy to install with washers or brackets
- The entire RS range can be fitted vertically or horizontally
