Rocksilk® RainScreen OSCB is a horizontal cavity barrier manufactured from rock mineral wool, shrink wrapped with a reactive intumescent strip, for use in ventilated cavities up to 450 mm.
Rocksilk® RainScreen OSCBs are used as horizontal open state cavity barriers in buildings with ventilated cavities. Rocksilk® RainScreen OSCBs contain a reactive intumescent strip which allows ventilation and drainage in a rainscreen cavity. The strip will expand in the event of a fire to fully seal the cavity providing fire resistance, preventing passage of smoke and flames.
Rocksilk® RainScreen OSCBs are also recommended for use against a steel, timber, masonry or reinforced concrete inner leaf where the construction has a ventilated cavity.
Rocksilk® RainScreen OSCBs should be partnered with Rocksilk® RainScreen Firestop Slab which is installed vertically, and Rocksilk® RainScreen Slabs for a complete rainscreen cavity system.
Rocksilk® RainScreen OSCB is a horizontal cavity barrier manufactured from rock mineral wool, shrink wrapped with a reactive intumescent strip, for use in ventilated cavities up to 450 mm. It forms part of a system with Rocksilk® RainScreen Slabs which provides fire resistance for up to 120 minutes integrity and 120 minutes insulation (EI120).
