Siderise RV vertical cavity barriers for rainscreen cladding applications consist of a non-combustible stone wool lamella core, with reinforced aluminium foil faces.

Siderise RV vertical cavity barriers are installed within the cavity, formed between the rainscreen facade and the inner structural wall, using the appropriate Siderise support brackets. Brackets are available in either galvanised mild steel (G) or stainless steel (S). The standard product length is 1200mm.

The construction of RV vertical cavity barriers offers resistance to the passage of fire. Additionally, by fully sealing the void, they assist ventilated façades to function by maintaining air-pressurisation compartmentation.

Significantly, their unique stone wool lamella core construction enables the vertical barriers to accommodate the serviceability movement normally associated with rainscreen façades.

Intersections between horizontal and vertical cavity barriers are simply abutted, with RFT 120/45 foil tape applied as detailed in the RV Installation Instructions. The leading edge compresses directly against the external envelope. No intumescent strip is required.
