Membrane manufactured by thermally bonding outer spun-bonded polypropylene layers and with an inner layer of microporous polypropylene film. The Integrate range of breather membranes feature high performance, integrated acrylic tapes allowing rapid installation without the need for battened overlaps, saving on costs, time and potential health and safety issues. All Easy-Trim Breather Membranes have been tested by BRE, to provide confidence that choice of membrane is fit for purpose.


  • Improved health and safety.
  • No tripping hazards and simpler than retrospectively installed taped laps.
  • Zone suitability is printed on both the inserts and membrane.
