While technically approved for roofing, its extra-wide format is primarily optimized for wall \"wrapping\" to ensure rapid and efficient installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"3,0,0\"\u003eExtra-wide 2.7m roll width enables seamless floor-to-ceiling coverage and faster installation\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,1,0\"\u003eHigh-performance tri-laminate construction offers excellent tensile and nail tear strength\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,2,0\"\u003eSuperior Class W1 water resistance protects the structure from moisture during construction\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,3,0\"\u003eExtremely breathable microporous core helps regulate moisture and prevents mould growth\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,4,0\"\u003eEnhances building airtightness when used with a compatible two-tape sealing system\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"5,0,0\"\u003eEach roll measures 2.7m in width by 100m in length, providing a total coverage of 270m²\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,1,0\"\u003eThe product has a fire classification of Class E according to EN 13501-1 standards\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,2,0\"\u003eIt is designed with a black front face and a grey reverse, featuring a 150mm overlap guide line for precision fitting\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,3,0\"\u003eThe membrane is lightweight at 102gsm, which simplifies handling on large-scale projects\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,4,0\"\u003eFor optimal performance, it should be installed on the cold side of the structural frame or over the insulation\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,5,0\"\u003eUV resistance is limited to one month, so the external cladding should be installed promptly after the membrane\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Novia","offers":[{"title":"Default Title","offer_id":57127691682124,"sku":"BM05697","price":247.36,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/novia-novia-black-construction-wrap-breather-membrane-1232467495.png?v=1776259490"},{"product_id":"novia-black-pro-roof-and-wall-breather-membrane","title":"Novia Black+ Pro Roof and Wall Breather Membrane","description":"\u003cdiv class=\"container\"\u003e\n\u003cdiv dir=\"ltr\" aria-busy=\"false\" aria-live=\"polite\" id=\"model-response-message-contentr_935ab606bcd817b7\" class=\"markdown markdown-main-panel stronger enable-updated-hr-color\"\u003e\n\u003cp data-path-to-node=\"0\"\u003eNovia Black+ Pro 150gsm is a high-performance, heavyweight breathable membrane designed for use in all pitched cold and warm roof structures, as well as insulated wall applications.
