ROCKWOOL Cavity Barriers can be used in both vertical and horizontal applications. In vertical applications, both flanges of the Cavity Barrier can be fixed to the inner leaf at 150mm centres, using staples or clout nails prior to compression fitting by outer cavity wall. In horizontal applications, only the top flange of the polythene sleeve should be fixed.
