Cavity Fire Stop Slab
The CCL Cavity Fire Stop Slab is a fire resistant barrier designed to prevent the spread of fire and smoke in closed state, non vented cavity constructions.
The CCL CFSS range is available in two standard sizes, both suitable for use in masonry and SFS build ups in horizontal and vertical applications with either 60/60 or 120/60 fire performance as shown below.
CCL Fire Stop Clips (FSCLIP) are not supplied with full slabs, but are available to order separately and are suitable for all cavity widths up to 300mm.
The CCL CFSS is designed to be installed with 5mm compression, therefore when cutting to the required cavity size add 5mm to the cavity width.
Once cut to size the CCL CFSS is installed under compression utilising the CCL Foldable Support Brackets (FSCLIP).
When installed vertically and providing the barrier is supported at the base and the internal and external surfaces are completed as the barrier is installed, the CCL FSCLIP may be omitted.
The CCL FSCLIP should be bent into a Z shape and penetrate the fire stop by a minimum of 60% of its overall width at a rate off 2 per length (approx, 300mm from end to end).
Lengths of the CFSS should be tightly abutted to each other and there should be no gaps present between the barrier and substrate.
The barrier should be securely fitted into the cavity ensuring it is compressed by approximately 5mm and the ends form a tight butt joint.
The fixing clip should then be mechanically fixed to the floor slab or inner leaf.
All joints should be sealed using 100mm CCL Foil Tape.
Products are supplied on showerproof shrink wrapped pallets, and should be stored in conditions out of direct sunlight and protected from the elements.
The Factory packaging is intended for protection during shipment and for short term job site storage. It is not intended for protection against the elements during long term outside storage. For long term storage, we recommend the product is stored indoors, in a dry location with the factory packaging removed. Product should not be stored in areas that contain food, or locations that may result in the product standing in water. Product should be a minimum of 100 mm (4 inches) above dry ground and kept on a solid flat surface.
DESCRIPTION
The CCL Cavity Fire Stop Slab (CFSS) range is designed for use vertically and horizontally in closed state, non-vented cavities from 50mm to 300mm.
Manufactured from high density, non-combustible rock mineral wool, faced on both sides with reinforced aluminium foil, the barriers are installed either friction, or mechanically fixed under 5mm compression.
Suitable for use on slab edge, masonry and SFS wall types, the CCL CFSS range achieves fire resistance performance of up to 240 minutes integrity and insulation on masonry and 240 minutes integrity and 60 minutes insulation on SFS substrates.
The CCL CFSS range is available in slab form in two sizes, either, 1200mm x 1000mm or 600mm x 1000mm, foil faced both sides with one face printed with cutting guides to facilitate on-site fabrication.
The CCL CFSS range is also available in factory produced sizes to suit the specified cavity width. Further details can be found on data sheet 2031.
Disclaimer
It is the responsibility of the customer to make the final choice when selecting for use in construction projects. CCL provide data in good faith, however the information provided is not a recommendation and decisions are not carried out by CCL. Where relevant, CCL products should be installed in line with test certification and in build ups that match the specific test.

Product Identification
Prior to installation, the CCL CFSS should be checked to ensure the performance matches the project requirement.
This can be carried out quickly onsite by checking the printing applied to the surface of the slab or factory produced barrier, which details the fire performance.
Additionally, the CCL CFSS contains a QR code linking to the BSI. Identify database.
