Siderise RV vertical cavity barriers for rainscreen cladding applications consist of a non-combustible stonewool 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 appropriate Siderise support brackets. Brackets are available in either galvanised mild steel (G) or stainless steel (S).

The standard product length is 1200mm

Resistance to Fire - Siderise RV vertical cavity barriers have been tested in accordance with EN 1366-4: 2006+A1: 2010. The cavity barriers maintained integrity (E) and insulation (I) requirements. This is detailed in the manufacturers' technical data sheet.

The tests have been undertaken to assess the ability of the vertical-cavity barrier products to reinstate the fire resistance of a lightweight aerated concrete supporting construction. This is the standard assembly for testing such cavity barrier products as it allows the performance of the individual barrier to be classified.
