Belonging to the PIR range of insulation boards, it has a low thermal conductivity of just 0.022 W\/mK which means maximum heat retention within the building structure. \u003cbr\u003e\u003cbr\u003eThese 100mm Recticel cavity boards have precision-cut straight edges, which means that the boards can butt up tightly against one another, minimising air gaps. They are flanked on either side by a multi-layered kraft and metal foil facing, which acts as a gas diffusion layer across air space. \u003cbr\u003e\u003cbr\u003e100mm Eurowall cavity boards come in 1200mm x 450mm, ideal to fit between brick ties in masonry cavity walls. They can be used in both new builds and extensions and will enhance the thermal performance of any cavity space.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eThickness:\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003e100 mm\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength:\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003e1200 mm\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth:\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003e450 mm\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo. Boards:\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003e6\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoverage:\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003e3.24 m²\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eR-value *:\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003e4.50 m²K\/W\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermal conductivity:\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003e0.022 W\/mK\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFire Certification:\u003c\/td\u003e\n\u003ctd\u003e\u003cb\u003eEuroclass F\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e* The R-value denotes the resistance to heat flow – the higher the R-value the more insulating the product is.\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Recticel","offers":[{"title":"Default Title","offer_id":47209364848958,"sku":"IREWC100-6","price":60.93,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/1281\/2350\/files\/recticel-eurowall-cavity-double.webp?v=1769130437"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/1281\/2350\/collections\/b9d71479a55c6aac925cfc04bdbb2cda-1-1.webp?v=1716203639","url":"https:\/\/diybuildingsupplies.co.uk\/collections\/cavity-slab-insulation.oembed?page=3","provider":"DIY Building Supplies","version":"1.0","type":"link"}
