01. 3 layers highly breathable and fully waterproof constructed from high tensile spun-bonded polypropylene layers and around micro porous polypropylene film;
02. Outer layer forms functional waterproof surface;
03. Middle layer breathable waterproof membrane;
04. Inner layer protects from abrasion and damage, also giving additional strength;
05. Enables fabric to allow moisture vapor to pass through, whilst remaining fully waterproof;
06. Breathable roofing underlay for use under tiles and sheeted roofs, over open rafters or on to fully boarded substrates;
07. Constructed from high tensile spun bonded polypropylene layers;
08. Higher levels of water-resistant;
09. Full moisture vapor permeability;
10. Breathable underlay for tiled and slated pitched roofs;
11. Eco-friendly to be completely recyclable;
12. Help keep building watertight, allowing moisture to escape but preventing air leakage which in turn contributes to heat and energy-saving;
13. Membrane should be surface applied, fixed directly to sheathing ply or block work;
14. Uses: mainly for timber frame wall applications, steel frame and concrete structures.
