At the heart of the kit is Novia's VariCheck FR AVCL, a Class B-s1,d0 fire rated variable membrane with an SD value that adjusts between 0.4 and 3.2 metres depending on ambient humidity conditions, CE marked to EN 13964. The variable SD value allows any moisture trapped within the construction to escape during summer months, reducing the risk of interstitial condensation damage over time. The kit includes two rolls of 30mm Double Sided Butyl Tape, one roll of 72mm Aluminium Foil Lap Tape and three cartridges of AirSeal 310 FR Sealant for sealing around penetrations and awkward junctions. All products are selected to work together for a complete, airtight 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 class=\"whitespace-normal break-words pl-2\"\u003eComplete DIY kit, everything needed for a compliant variable AVCL installation included\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eVariCheck FR AVCL CE marked to EN 13964 for assured performance\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eClass B-s1,d0 fire rating, valid for use on A1 and A2 rated substrates with no cavity\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eVariable SD value of 0.4 to 3.2 metres adapts to seasonal humidity conditions, reducing interstitial condensation risk\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e30mm Double Sided Butyl Tape secures all laps and joints with a minimum 30mm bond as required for AVCL applications\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e72mm Aluminium Foil Lap Tape reinforces and finishes critical overlaps\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAirSeal 310 FR Sealant seals around penetrations and awkward junctions for a continuous airtight installation\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eRemoves the guesswork, compatible products specified and pre-selected\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 class=\"whitespace-normal break-words pl-2\"\u003eKit contents: 1 x VariCheck FR AVCL (1.5m x 50m \/ 75m²), 2 x Double Sided Butyl Tape (30mm x 30m), 1 x Aluminium Foil Lap Tape (72mm x 45m), 3 x AirSeal 310 FR Sealant (310ml cartridge)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMilky white finish with 150mm overlap lines to aid correct installation\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eValid for use on A1 and A2 rated substrates where there is no cavity\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAirSeal 310 FR Sealant seals joints up to 35mm and is flexible and over-paintable once cured\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAlways follow current building regulations and good practice guidance for airtightness and vapour control\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Novia","offers":[{"title":"Default Title","offer_id":57127686897996,"sku":"BM05675","price":213.77,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/NoviaVaricheckFR.png?v=1776260594","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/novia-varicheck-fr-avcl-diy-kit","provider":"Construction Supplies UK","version":"1.0","type":"link"}
