{"product_id":"visqueen-vapour-barrier-2-0m-x-50m","title":"Visqueen Vapour Barrier 2m x 50m","description":"\u003cp dir=\"ltr\"\u003eVisqueen Vapour Barrier is a green tinted, semi-transparent polyethylene air and vapour control layer (AVCL) designed to reduce the risk of interstitial condensation within floor, wall and roof constructions in medium condensation risk buildings. By restricting the passage of warm, moist air from within the heated building envelope into the surrounding structure, it protects insulation, framing and finishes from the damaging effects of moisture accumulation over time, while also contributing to the overall airtightness of the building.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt is installed on the warm side of the insulated structure — between the insulation and the interior finish — and must be kept continuous across the entire building element, with all laps, penetrations and abutments properly sealed using compatible Visqueen taping products. The semi-transparent green tint allows stud locations to remain visible through the membrane during installation, making it easier to align and fix without lifting the barrier to find the framing beneath.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSupplied in a single wound, unfolded 2.0m x 50m roll, the membrane has a thickness of 0.3mm and a water vapour resistance factor (µ) of 550,000, making it highly effective at resisting vapour transmission. It is UKCA, UKNI and CE marked to EN 13984:2013, air leakage tested to BS EN 1026:2016, and should be installed in accordance with BS 5250:2021 Management of Moisture in Buildings. The barrier is mechanically secured by overboarding with plasterboard or construction board, with joints lapped by a minimum of 75mm and sealed with Visqueen FR Single Sided Vapour Tape. Compatible system components include Visqueen FR Double Sided Vapour Tape for bonding to structural components and VisqueenPro Vapour Edge Tape for junctions.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eReduces the risk of interstitial condensation in floor, wall and roof constructions\u003c\/li\u003e\n\u003cli\u003eImproves the airtightness of the building — contributes to Part L compliance\u003c\/li\u003e\n\u003cli\u003eSemi-transparent green tint — stud locations remain visible through the membrane during installation\u003c\/li\u003e\n\u003cli\u003eSingle wound roll — no folds or creases that could compromise performance or installation\u003c\/li\u003e\n\u003cli\u003eWater vapour resistance factor µ 550,000 — highly effective vapour control\u003c\/li\u003e\n\u003cli\u003eEquivalent air layer thickness Sd: 165m\u003c\/li\u003e\n\u003cli\u003eAir leakage tested to BS EN 1026:2016 — result: 0 m³\/h\/m² at ±100 Pa\u003c\/li\u003e\n\u003cli\u003eUKCA, UKNI and CE marked to EN 13984:2013\u003c\/li\u003e\n\u003cli\u003eSuitable for use in floors, walls and roofs\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001, ISO 14001 and ISO 45001 certified management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eGood to know\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eRoll size: 2.0m wide x 50m long; thickness: 0.3mm; mass: 270 g\/m²\u003c\/li\u003e\n\u003cli\u003eWater vapour permeability: 0.22 g\/m²\/day; water vapour resistance: 825 MNs\/g\u003c\/li\u003e\n\u003cli\u003eTensile strength: 20 N\/mm² (MD), 19 N\/mm² (CD); flexibility at low temperature: -15°C\u003c\/li\u003e\n\u003cli\u003eInstall on the warm side of the insulated structure in accordance with BS 5250:2021\u003c\/li\u003e\n\u003cli\u003eLap joints minimum 75mm, sealed with Visqueen FR Single Sided Vapour Tape applied centrally over the lap\u003c\/li\u003e\n\u003cli\u003eBond to structural components using Visqueen FR Double Sided Vapour Tape\u003c\/li\u003e\n\u003cli\u003eSeal junctions with VisqueenPro Vapour Edge Tape\u003c\/li\u003e\n\u003cli\u003eDo not install below 0°C; protect from puncturing or stretching during overboarding\u003c\/li\u003e\n\u003cli\u003eAlways refer to the latest Visqueen Vapour Barrier technical datasheet before specification or installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Visqueen","offers":[{"title":"Default Title","offer_id":60943892939086,"sku":"BM005850","price":265.01,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/1083\/0670\/files\/visqueen-visqueen-vapour-barrier-avcl-2m-x-50m-roll-bm005850-membranes-1259887741.jpg?v=1790270174","url":"https:\/\/www.insulationuk.co.uk\/products\/visqueen-vapour-barrier-2-0m-x-50m","provider":"Insulation UK","version":"1.0","type":"link"}
