Breathable Membranes

Breather Membranes

See Details

The purpose of the membrane is to allow water vapour to permeate through from the insulation into the cavity above and yet prevent water from the cavity entering the quilt. Breather membranes are installed over the top of quilt insulation and below the external profiled sheet.
