Description 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. Using fireproof sponge instead of mineral wool. 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. Advantages – 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– The entire RS range can be fitted vertically or horizontally, with fixing brackets already in place Application This barrier comes supplied with 4 fixing brackets which can be simply screwed, nailed or spit nailed to the internal wall (pre-drilled holes are suitablefor up to 12mm size screws). The non-fibrous products used in this barrier makes it even easier to install. The barrier can be easily cut with a sharp knife or blade. If during installation you find wall imperfections, these can be filled with Envirograf Intumescent Mastic (Product 58).
