The medium weight waterproof roofing underlay is manufactured by thermally bonding outer spun-bonded polypropylene layers to an inner layer of micro-porous polypropylene film. The Master Breather membrane can be applied in direct contact with thermal insulation with recommended overlap
  • High Breathability - Eliminates Roof Space Ventilation

Install with the black-printed cutting guide uppermost and lapped to shed water out and down the slope. The vapour permeable Easytrim Pro-Felt membrane can be installed without the need for ventilation given that the roof remains air tight and convection free for the life of the structure. In cold non ventilated roofs NHBC section 7.2 prescribes a 5mm continuous ridge ventilation. TheEasy-trim dry ridge system can be used to acheive this.
