THE MANUFACTURER’S WALL CAVITY BARRIER (RED EDITION) FOR MASONRY CONSTRUCTION AVOIDS THE PROBLEM OF ‘BRICK PUSH OFF’ ASSOCIATED WITH BARRIERS INSTALLED UNDER COMPRESSION… AIM offers effective fire performance under zero compression
Acoustic & Insulation Manufacturing (AIM) has demonstrated that its Wall Cavity Barrier (Red Edition) provides effective fire performance without compression in masonry construction. The new zero-compression solution means AIM’s Wall Cavity Barrier (Red Edition) can be installed easily with green brickwork or other forms of masonry cladding and avoids the problem of ‘brick push off’ which can be associated with barriers installed under compression. Acting as a fire and smoke barrier for masonry cavity walls, AIM’s Wall Cavity Barrier (Red Edition) is used to provide a fully-closed cavity fire barrier along compartmentation lines in the external cavity wall in a wide variety of construction

types, including masonry and SFS. The different barrier thicknesses of 75mm, 100mm and 125mm provide 30, 60 and 120-minute fire ratings to BS EN 1366-4. Applicable to masonry construction only, zero compression installation has been tested horizontally and vertically for use within voids up to 400mm. The barrier is installed and then the bricks built up against its edge. Once the mortar has set, AIM Acrylic Intumescent Mastic should
