A multi-layer vapour control layer made from virgin polyethylene with reinforcing grid and aluminium layer giving exceptionally high vapour resistance.

The high resistance of the Reflex 275 makes it suitable for use within buildings with higher levels of humidity, such as swimming pools, sports halls and kitchens. It is a loose-laid membrane and therefore intended for use within mechanically fastened warm roof waterproofing systems. Joints should be sealed with Monobond LT sealant tape.
