Complies with EN 13501-1 Fire Classification B-s1,d0 and is CE marked to EN 13964. Suitable for use in high rise applications under Fire Safety Approved Document B. The variable sd value (0.4m to 3.2m) means the membrane adapts seasonally, less permeable in colder months and more permeable in warmer months, minimising interstitial condensation without over-restricting vapour movement. Suitable for insulated wall and roof applications, and floor applications where a fire rating is not required. Available on NBS Chorus and NBS Source. Supplied as a 1.5m x 50m roll.\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 class=\"whitespace-normal break-words pl-2\"\u003eClass B-s1,d0 fire rating suitable for high rise applications under Fire Safety Approved Document B\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eVariable sd value (0.4m to 3.2m) adapts seasonally to changes in local humidity levels\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLess permeable in colder months, more permeable in warmer months\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMinimises interstitial condensation without over-restricting vapour movement\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCost-effective fire rated solution for standard and high rise constructions\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCE marked to EN 13964\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 class=\"whitespace-normal break-words pl-2\"\u003eClass B-s1,d0 fire classification is valid when installed flush against a substrate with fire class A2-s1,d0 or A1, such as 12mm plasterboard, with no cavity between product and substrate\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSuitable for floor applications only where a fire rating is not required\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMilky white in colour with 150mm overlap lines\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAll laps and edges must be fully sealed and taped\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eUse Novia 30mm Double Sided Butyl Tape for all overlaps and around framework\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eUse Novia Aluminium Foil Tape or Novia Metallised BOPP Tape over overlaps to ensure a fully airtight seal\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAny mechanical fixings must penetrate through the butyl tape to seal around punctures\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eNovia AirSeal 310 FR sealant can be used where additional sealing is required, for example at internal corners, floor sections or window reveals\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eFor a full Class B installation use in conjunction with Novia FR Breather Membrane or Novia UV Facade FR Breather Membrane for open facade applications\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAvailable on NBS Chorus and NBS Source\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSupplied as a 1.5m x 50m roll (75m²)\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Novia","offers":[{"title":"Default Title","offer_id":57127696597324,"sku":"BM05718","price":159.71,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/novia-novia-varicheck-fr-avcl-1232467680.png?v=1776258737","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/novia-varicheck-fr-avcl","provider":"Construction Supplies UK","version":"1.0","type":"link"}
