BREATHER MEMBRANES range

Breather membrane

ACTIS reflective breather membranes are designed to improve the thermal performance of roofs and walls. Installed over the roof structure they protect insulation from air and water infiltration and enable water vapour to be evacuated.

Solutions & Systems

BOOST'R HYBRID ROOF

BOOSTR HYBRID ROOF is a variant of BOOST R HYBRID providing all the same features and benefits but has been specifically designed for use on roofs. The water vapour permeable roofing underlay also acts as a wind barrier and has been created with a built in self-adhesive lap, facilitating the sealing of joints between adjacent sheets.

BOOSTR HYBRID ROOF is a multifoil insulation product with a built-in breather membrane function offering exceptional thermal performance.
