Supplied at 75mm thick in 1200 x 455mm slabs covering 4.36m² per pack, it is built into the cavity as the wall is constructed, and suits extensions matching an existing wall, garages and outbuildings, and refurbishment work where a narrower cavity has to be maintained.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe 37 designation refers to the slab's thermal conductivity of 0.037 W\/mK, which at 75mm gives an R-value of around 2.03 m²K\/W. In a narrower cavity the conductivity rating carries more weight than it does in a deep one, since there is less depth available to make up the difference, and DriTherm 32 is the higher-performing alternative at the same thickness where a tighter U-value has to be met.\u003c\/p\u003e\n\u003ch5 dir=\"ltr\"\u003eSpecification:\u003cbutton type=\"button\" class=\"btn btn-link lnkChangeSection\"\u003e\u003c\/button\u003e\n\u003c\/h5\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"accordion\" class=\"product-page__accordian\"\u003e\n\u003cdiv id=\"collapse_specs\" class=\"collapse show\"\u003e\n\u003cdiv class=\"product-page__spec-table-wrapper\"\u003e\n\u003ctable class=\"product-page__spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eKnauf\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eCoverage\u003c\/td\u003e\n\u003ctd\u003e4.36m2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e75mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eLength\u003c\/td\u003e\n\u003ctd\u003e1200mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eThermal Conductivity\u003c\/td\u003e\n\u003ctd\u003e0.037W\/mk\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eThickness\u003c\/td\u003e\n\u003ctd\u003e75mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e455mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-12 col-md-6\"\u003e\n\u003cform action=\"https:\/\/www.itsplaneandsimple.com\/products\/setpostcode\" id=\"frmChoosePostcode\"\u003e\n\u003cdiv class=\"row choose-delivery stacked\"\u003e\n\u003cdiv class=\"col-10\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/form\u003e\n\u003cdiv class=\"col-12\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Home \u0026 Trade","offers":[{"title":"Default Title","offer_id":55403681874247,"sku":"INS011","price":25.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/7759\/6999\/files\/INS011.jpg?v=1791879161","url":"https:\/\/homeandtrade.co.uk\/products\/knauf-dritherm-cavity-slab-37-75mm-1200mm-x-455mm-4-36m2","provider":"Home \u0026 Trade","version":"1.0","type":"link"}
