{"product_id":"single-flange-thermal-cavity-closer","title":"Single Flange Thermal Cavity Closer","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eManthorpe Single Flange Thermal Cavity Closer G242 is a lightweight thermally efficient cavity closer with a single flange design, developed for use around timber door and window frames in cavity wall construction. The single flange configuration suits applications where a double flange is not required or practical, particularly around timber frame openings.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe G242 has a thermal conductivity of 0.035 W\/mK, providing effective insulation at the cavity closure and helping to minimise heat loss and cold bridging at window and door openings.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA key feature of the G242 is its tested performance as part of a complete cavity barrier detail. When installed as a whole detail including timber window or door frames and plasterboard lining, it can be used to satisfy the requirements of a cavity barrier as described in Approved Document B of the Building Regulations — an important compliance consideration for residential and commercial construction.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCan satisfy Part B Building Regulations cavity barrier requirements when used as part of complete tested detail\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTested detail includes timber window or door frames and plasterboard lining\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePrevents cold bridging, moisture ingress and air infiltration\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eLightweight and easy to handle\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\u003eDPC recommended under window sills in line with current building practice\u003c\/li\u003e\n\u003cli\u003eSimply cut to length on site, no special tools required\u003c\/li\u003e\n\u003cli\u003eThermal conductivity 0.035 W\/mK\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e \u003c\/p\u003e","brand":"Manthorpe","offers":[{"title":"50mm","offer_id":57530882294092,"sku":"BM06314","price":48.75,"currency_code":"GBP","in_stock":true},{"title":"65mm","offer_id":57530882326860,"sku":"BM06315","price":52.07,"currency_code":"GBP","in_stock":true},{"title":"75mm","offer_id":57530882359628,"sku":"BM06316","price":55.81,"currency_code":"GBP","in_stock":true},{"title":"90mm","offer_id":57530882392396,"sku":"BM06317","price":55.81,"currency_code":"GBP","in_stock":true},{"title":"100mm","offer_id":57530882425164,"sku":"BM06318","price":59.38,"currency_code":"GBP","in_stock":true},{"title":"125mm","offer_id":57530882457932,"sku":"BM06319","price":91.68,"currency_code":"GBP","in_stock":true},{"title":"135mm","offer_id":57530882490700,"sku":"BM06320","price":96.58,"currency_code":"GBP","in_stock":true},{"title":"150mm","offer_id":57530882523468,"sku":"BM06321","price":99.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/manthorpe-cavity-closer-single-flange-thermal-cavity-closer-1232550688.jpg?v=1776343729","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/single-flange-thermal-cavity-closer","provider":"Construction Supplies UK","version":"1.0","type":"link"}
