Gray Foam Board Insulation","description":"\u003cp\u003eRigid foam board insulation in gray, supplied as a full sheet for continuous insulation work. Boards of this type are cut and fitted in place to add a continuous layer of thermal resistance over framing, under slabs, or against foundation walls, where batt insulation cannot bridge the framing members.\u003c\/p\u003e\n\u003cp\u003eGray expanded polystyrene board is a closed-cell foam product that holds its shape, cuts cleanly with a utility knife or fine-tooth saw, and can be fastened with plastic-cap nails, insulation washers, or foam-compatible adhesive. Panel edges are butted tight and the joints taped or sealed so the insulating layer performs as a continuous plane.\u003c\/p\u003e\n\u003cp\u003eAs with all rigid foam, the board must be covered by an approved finish or thermal barrier in occupied spaces, and adhesives, primers, and sealants used with it should be checked for polystyrene compatibility.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGray rigid foam board supplied as a single full-size panel\u003c\/li\u003e\n\u003cli\u003eClosed-cell foam structure resists moisture absorption and holds its dimensions\u003c\/li\u003e\n\u003cli\u003eCuts with a utility knife or fine-tooth saw and scores cleanly for tight-fitting joints\u003c\/li\u003e\n\u003cli\u003eLightweight sheet a single worker can handle and fasten\u003c\/li\u003e\n\u003cli\u003eAccepts plastic-cap fasteners, insulation washers, and foam-compatible adhesive\u003c\/li\u003e\n\u003cli\u003eSuitable for continuous insulation layers that reduce thermal bridging through framing\u003c\/li\u003e\n\u003cli\u003eRequires a code-approved covering or thermal barrier when left exposed in occupied areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous exterior insulation over wall sheathing or framing\u003c\/li\u003e\n\u003cli\u003eInterior furring-out of basement and foundation walls\u003c\/li\u003e\n\u003cli\u003eUnder-slab and slab-edge insulation in new concrete work\u003c\/li\u003e\n\u003cli\u003eInsulating masonry and concrete block cavities or interior faces\u003c\/li\u003e\n\u003cli\u003eRoof and deck insulation layers beneath membrane or cover board assemblies\u003c\/li\u003e\n\u003cli\u003eFilling voids and insulating around rim joists and headers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Rigid foam board insulation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Expanded polystyrene foam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Panel \/ sheet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold By:\u003c\/strong\u003e Piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"product-specs\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eColor\u003c\/th\u003e\n\u003ctd\u003eGray\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"ARCH Building Supply","offers":[{"title":"Default Title","offer_id":55048725102931,"sku":"GF3R","price":82.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/arch-placeholder-coming-soon_7dc0a9eb-495f-4dbe-b208-c0e98c46b652.webp?v=1790259802","url":"https:\/\/arch-9365.myshopify.com\/es\/products\/3-in-x-4-ft-x-8-ft-gray-foam-board-insulation-gf3r","provider":"ARCH","version":"1.0","type":"link"}
