Fire-Retardant Treated CDX Plywood","description":"\u003cp\u003eFire-retardant treated CDX plywood is a structural softwood panel that has been pressure-impregnated with fire-retardant chemicals rather than simply surface-coated, so the treatment carries through the thickness of the sheet and is not lost when the panel is cut or drilled. It is the panel specified where a building official or an architect calls for fire-retardant treated wood in sheathing, roof decking or blocking.\u003c\/p\u003e\n\u003cp\u003eThe CDX designation describes the veneer grades and the glue: a C-grade face, a D-grade back and an exterior-type adhesive bond. The result is a sheathing-grade panel that tolerates the weather exposure normal to construction, with visible knots, plugs and patches on the face since it is intended to be covered by roofing, siding or finish materials.\u003c\/p\u003e\n\u003cp\u003ePanels are sanded only lightly if at all and cut, nailed and screwed with ordinary carpentry tools. Treated plywood is generally fastened with corrosion-resistant hardware, and cut edges should be handled according to the treater's instructions.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSoftwood structural panel pressure-treated with fire-retardant chemicals throughout the sheet, not a surface coating\u003c\/li\u003e\n\u003cli\u003eCDX construction: C-grade face veneer, D-grade back veneer, exterior-type adhesive bond\u003c\/li\u003e\n\u003cli\u003eSheathing-grade appearance with knots, patches and plugs; intended to be covered by finish materials\u003c\/li\u003e\n\u003cli\u003eCross-laminated veneer layup gives strength and stiffness in both panel directions\u003c\/li\u003e\n\u003cli\u003eStandard sheet format cuts, nails and screws with conventional framing tools\u003c\/li\u003e\n\u003cli\u003eTreatment remains effective at cut edges and drilled holes because it is impregnated into the wood\u003c\/li\u003e\n\u003cli\u003eBest paired with corrosion-resistant fasteners and connectors, as with other treated wood products\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRoof decking and wall sheathing where fire-retardant treated wood is specified\u003c\/li\u003e\n\u003cli\u003eInterior partitions and shaft walls in multi-family and commercial construction\u003c\/li\u003e\n\u003cli\u003eBacking panels, blocking and plywood backer boards in electrical and telecom rooms\u003c\/li\u003e\n\u003cli\u003eStair enclosures, corridors and other assemblies subject to fire-retardant requirements\u003c\/li\u003e\n\u003cli\u003eConcealed framing and furring work in renovation of existing commercial buildings\u003c\/li\u003e\n\u003cli\u003eTemporary construction enclosures and barricades where treated material is required\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 Fire-retardant treated plywood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Grade:\u003c\/strong\u003e CDX (C face, D back, exterior glue)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e Pressure-impregnated fire retardant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Softwood veneer plywood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 3\/4 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\u003eSurface:\u003c\/strong\u003e Unsanded sheathing face\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold By:\u003c\/strong\u003e Each (sheet)\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\u003e3\/4\" 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":55048723759443,"sku":"CDX3448FIRE","price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/arch-placeholder-coming-soon_37285fff-027d-4e4a-a721-99d81f6b5f49.webp?v=1790259794","url":"https:\/\/arch-9365.myshopify.com\/products\/3-4-in-x-4-ft-x-8-ft-fire-retardant-treated-cdx-plywood-cdx3448fire","provider":"ARCH","version":"1.0","type":"link"}
