{"product_id":"visqueen-nf-vapour-barrier-air-vapour-control-layer","title":"Visqueen NF Vapour Barrier | Air \u0026 Vapour Control Layer","description":"\u003cp\u003eVisqueen NF Vapour Barrier is a high-performance air and vapour control layer built from a co-extruded, multi-layer thermoplastic construction at 0.4mm (400 micron) thick. Positioned on the warm side of the insulation, it resists the passage of moisture-laden air into the building fabric, helping to control interstitial condensation and protect both the structure and the insulation. The membrane is transparent with a blue tint and is suitable for use across floor, wall and roof constructions. It carries UKCA, UKNI and CE marking to EN 13984:2013 in support of Building Regulation and warranty provider requirements, and is rated for all humidity classes under BS 5250:2021.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCo-extruded, multi-layer thermoplastic construction at 0.4mm (400 micron) thick\u003c\/li\u003e\n\u003cli\u003eSuitable for use within floor, wall and roof constructions\u003c\/li\u003e\n\u003cli\u003eUKCA, UKNI and CE marked to EN 13984:2013, meeting Building Regulation and warranty provider requirements\u003c\/li\u003e\n\u003cli\u003eRated for all humidity classes under BS 5250:2021\u003c\/li\u003e\n\u003cli\u003eSupplied as a single wound roll\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEach single wound roll covers 104.4m² (2.4m wide x 43.5m long).\u003c\/li\u003e\n\u003cli\u003eA vapour barrier or AVCL offers high vapour resistance and is close to impermeable, differing from a vapour check, which slows rather than stops the passage of vapour.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Visqueen","offers":[{"title":"Default Title","offer_id":58362367836492,"sku":"BM06694","price":482.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/visqueen-visqueen-nf-vapour-barrier-air-vapour-control-layer-1253865143.jpg?v=1786462632","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/visqueen-nf-vapour-barrier-air-vapour-control-layer","provider":"Construction Supplies UK","version":"1.0","type":"link"}
