Description
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.
Features and benefits:
- Siderise RV Cavity Barriers provides a fire resistance of up to 120 minutes of integrity and 120 minutes insulation. (Siderise RV-120/120 & Siderise RV120/120X).
- Siderise RV Cavity Barriers are fully compliant and meet ASFP guidelines.
- Siderise RV Cavity Barriers are suitable for vertical (full seal) applications.
- Siderise RV Cavity Barriers accommodate cladding movement.
- Siderise RV Cavity Barriers are tested to BS EN 1366-4:2006+A1:2010.
- Siderise RV Cavity Barriers are Third-party approved: Intertek US(WHI20-32944302 ), Intertel UK(WHI-09-02-22-000001-02), IFC Certification (IFCC 1712).
- Siderise RV Cavity Barriers have been used in several large-scale system tests such as BS 8414 (1 and 2) and NFPA 285.
