Fire protection

556 Firestop Slab has been developed to provide two hours firestopping in building cavities up to 300 mm wide. The system has been tested by Warrington Fire Research to BS EN 476-20.It is manufactured using 75 mm thick high density rock fibre slab foil faced on both sides. Firestop Slab has rebated ends for a secure fit and is available in full slabs 1160 x 900 mm, or factory cut to size.It can provide two hours fire resistance in masonry cavity voids and between the edge of a concrete floor slab and curtain walling systems.Suitable for cavities 50–300 mm wide.

Manufactured using polythene enclosed non combustible rockfibre in bespoke sizes designed to be compressed by 15 mm within the cavity - this 'made to measure' cavity barrier design provides a minimum of 1 hour fire resistance and is crucial in sound applications where 'flanking transmission' can be the weak link of an otherwise robust construction. Meets the requirements of:2000 Building Regulations (E&W) Approved Document B (Fire Safety).2003 Building Regulations (E&W) Approved Document E (Sound Resistance).Robust Details Part E.NHBC Standards 2005.Tested by Warrington Fire Research to provide one hour fire resistance – double the minimum requirement. Meets Parts B and E (including Robust Details) of the Building Regulations (E&W) 2000. Mayplas Deluxe and Party Wall Ranges have been assessed to provide two hours fire resistance.
