Polyisocyanurate (ISO) Board","description":"\u003cp\u003ePolyisocyanurate (ISO) board is a rigid foam insulation panel made from closed-cell polyiso foam bonded between facers. It is one of the most common rigid boards used in commercial roofing and in wall and ceiling assemblies where a high level of insulation is wanted from a relatively thin panel.\u003c\/p\u003e\n\u003cp\u003eThe closed-cell foam core resists moisture absorption, and the facers give the board enough stiffness to be handled, cut and fastened on site. Panels cut cleanly with a utility knife or a fine-tooth saw and are secured with plates and fasteners, adhesive, or mechanical furring depending on the assembly.\u003c\/p\u003e\n\u003cp\u003eBecause foam plastic insulation is combustible, polyiso is installed behind an approved thermal barrier or covering when used on the interior of a building, and joints are typically taped or sealed where the board also serves as part of the air control layer.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRigid closed-cell polyisocyanurate foam core with bonded facers\u003c\/li\u003e\n\u003cli\u003eFaced board is dimensionally stable and stiff enough to handle and fasten without a backing panel\u003c\/li\u003e\n\u003cli\u003eClosed-cell structure resists water absorption compared with open-cell foams\u003c\/li\u003e\n\u003cli\u003eStandard 4 ft. x 8 ft. panel format lays out on 16 in. and 24 in. framing centers\u003c\/li\u003e\n\u003cli\u003eCuts with a utility knife, hand saw or hot knife for tight fits around penetrations\u003c\/li\u003e\n\u003cli\u003eAccepts mechanical fastening with insulation plates and screws or compatible adhesives\u003c\/li\u003e\n\u003cli\u003eJoints can be taped or sealed to contribute to the continuous air barrier\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous insulation over low-slope commercial roof decks\u003c\/li\u003e\n\u003cli\u003eExterior continuous insulation behind cladding on wall assemblies\u003c\/li\u003e\n\u003cli\u003eInterior furred-out insulation on masonry and concrete walls\u003c\/li\u003e\n\u003cli\u003eInsulating foundation and knee walls above grade\u003c\/li\u003e\n\u003cli\u003eCeiling and soffit insulation in unconditioned spaces\u003c\/li\u003e\n\u003cli\u003eRe-roofing and roof recover assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Rigid foam board insulation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polyisocyanurate (ISO) closed-cell foam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 1-1\/2 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Size:\u003c\/strong\u003e 4 ft. x 8 ft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold By:\u003c\/strong\u003e Each\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\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e1-1\/2\" x 4' x 8'\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":55048725299539,"sku":"ISO112","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/arch-placeholder-coming-soon_8ece6e5c-a2d5-4e68-84fe-4e6585217818.webp?v=1790259803","url":"https:\/\/arch-9365.myshopify.com\/es\/products\/1-1-2-in-x-4-ft-x-8-ft-polyisocyanurate-iso-board-iso112","provider":"ARCH","version":"1.0","type":"link"}
