RainScreen FFCB (102 mm) 100 mm
Indoor Air Comfort – Eurofins
Certificate type
A patented cavity barrier manufactured from rock mineral wool, that is designed to be face-fixed to Rocksilk® RainScreen Slab as the masonry façade is constructed.
Rocksilk® RainScreen FFCB is used as a cavity barrier in closed state cavities to provide fire resistance between compartments, floor levels and cavity openings such as windows or doors. It is suitable for use in partially filled masonry cavities where the inner leaf is concrete/masonry/steel or timber frame.
A 100mm Rocksilk® RainScreen FFCB will provide fire resistance of
30 minutes insulation and 90 minutes integrity, while a 200mm Rocksilk® RainScreen FFCB will provide fire resistance of 90 minutes insulation and integrity.
When factory finished to suit cavity dimensions, Rocksilk® RainScreen FFCB comes with three ties per barrier included in the box.
When ordered as a full slab, ties should be ordered separately.
They should be a suitable depth such that they sit in contact with the sheathing board when installed. The ties can be easily trimmed to size.
Rocksilk® RainScreen FFCB can only be used in conjunction with Rocksilk® RainScreen Slab.
Knauf Insulation Rocksilk® RainScreen FFCB is a patented cavity barrier manufactured from rock mineral wool, that is designed to be face-fixed to Rocksilk® RainScreen Slab as the masonry façade is constructed. It forms part of a tested system with Rocksilk® RainScreen Slabs which together provide fire resistance for up to 90 minutes insulation and integrity (EI90). It is non-combustible, achieving the best possible Euroclass A1 reaction to fire classification and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.
