Designed for use in a fully supported or unsupported tiled, slated or metal roof system.\u003c\/p\u003e\n\u003cp\u003eThe high vapour permeability and waterproof nature of the membrane combined with excellent tensile\/tear strength and high wind uplift resistance make Vent3 the professionals choice as the ultimate breather membrane. It is equally suitable whether draped unsupported over rafters, laid directly over insulation or sarking boards (Scottish Practice).\u003c\/p\u003e\n\u003cp\u003eThe outer layer forms the functional waterproof surface, the middle layer is the breathable waterproof membrane, and the inner layer protects the membrane from abrasion and damage, also giving additional strength. This enables the fabric to allow moisture vapour to pass through, whilst remaining fully waterproof. The upper surface is Blue, printed with the trade name and head lap lines. \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBBA Certified\u003c\/li\u003e\n\u003cli\u003eCold \u0026amp; warm roof application\u003c\/li\u003e\n\u003cli\u003e3 Layer spun-bonded membrane\u003c\/li\u003e\n\u003cli\u003eClean \u0026amp; easy to use\u003c\/li\u003e\n\u003cli\u003eExcellent tensile strength\u003c\/li\u003e\n\u003cli\u003eNo gusting wind noise\u003c\/li\u003e\n\u003cli\u003eUV stable for up to 3 months\u003c\/li\u003e\n\u003cli\u003eExcellent nail tear resistance\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cromar","offers":[{"title":"Default Title","offer_id":51654646825338,"sku":null,"price":65.1,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0625\/0299\/4141\/files\/CROMAR_VENT_3_50.avif?v=1759783581","url":"https:\/\/www.hgroofingsupplies.co.uk\/products\/cromar-vent3%c2%ae-breathable-membrane-1m-x-50m-50m2-roll","provider":"HG Roofing Supplies","version":"1.0","type":"link"}
