Specification
Fixing : CCL Timber Cavity Barriers do not rely on their polythene flanges to hold them in place . They are supplied 10mm to 15mm thicker than the cavity in which they are to be installed . This ensures a tight fit as they are held in place by compression between the inner leaf and outer brickwork . During vertical installation , both flanges are fixed to the inner timber sheathing using non - corrosive clout nails or staples at 150mm centres . During horizontal installation the upper flange only is stapled or nailed to the inner timber sheathing . The breather membrane should be cut to overlap the upper flange of the Timber Cavity Barrier . Special attention must be paid to the joints to ensure that these are very closely butted . Cavity barriers may fail at the joints if a gap is left . The Cavity Barrier should fully fill the whole cavity .
Dimensions
CCL Timber Cavity Barriers are supplied in 1200mm lengths and are factory cut to suit cavity widths from 50mm to 150mm . Cavities wider than 150mm can be accommodated , although CCL Firestop Slab may be a more suitable application .
