Knauf Insulation believes that its Rocksilk RainScreen FFCB built-in cavity barrier is the first of its kind designed to be affixed to the surface of insulation during the construction of masonry facades.
Being attached directly to the insulation surface as the brickwork is constructed eliminates the need for post-installation insulation cuts. This innovation streamlines installation, minimizes waste, and reduces the risk of performance-compromising air gaps.
The product is part of a certified system designed to provide up to 90 minutes of fire resistance (EI90) in the residual cavities of buildings with masonry facades and is classified as non-combustible with a Euroclass A1 reaction to fire classification.
Because it is installed between the insulation and the masonry façade, just three width and depth variations are required to cover all sizes of cavity – something that makes product selection much easier.
