ARC Fire Stop Strip is designed to prevent the passage of smoke and flames through narrow voids in the construction, offering up to four hours fire integrity when installed between masonry or concrete. Possible applications include: top of masonry walls under the soffit, above partitions, expansion joints, and between ceilings and walls.
ARC Fire Stop Strip is easily installed, simply push fitting into the void to create a friction fit. No adhesive or mastic is required, but care must be taken to ensure no gaps remain as these will compromise the fire integrity.
ARC Fire Stop Strip has been fire tested at Warrington Fire Research, achieving up to four hours fire integrity when installed between block and concrete structural elements. Tests were carried out in accordance with BS476 Pt 20 1987. Certifire scope: CF5402
