ARC T-Barrier Pitched Roof for 75mm Party Wall Cavity - Fire Barrier Between Party Wall and Roof Covering - Pack of 9

ARC T-Barrier Pitched Roof for 75mm Masonry Party Wall Cavity is a non-combustible rockfibre mineral wool cavity fire barrier that stops fire between party wall and roof covering. ARC T-Barrier Pitched Roof is designed to provide a fire, thermal and acoustic barrier between the top of the party wall masonry work and the underslaters felt. They are fitted along the length of the roof pitch, from soffit to apex ensuring an effective and consistent barrier. The party wall masonry work is stopped at 25mm below the top of the adjacent roof trusses, and then the ARC T-Barrier Pitched Roof is compression fitted within the gap, satisfying the NHBC recommendation for a mineral wool fire barrier. ARC T-Barrier Pitched Roof achieves up to four hours fire integrity closing the top of the party wall cavity.
