Keep the fanfold flat and lapped shingle-style so the new siding sits even, and do not leave crushed or torn panels behind the new cladding. Choose a thicker rigid board instead when a specified continuous R-value must be met.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eFollow local building code requirements for continuous insulation and vapor management in your climate zone, and keep polystyrene away from open flame during storage and installation.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eOrder the Insulfoam R-Gard 1\/2 in. fanfold insulation bundle to back your next siding job.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Insulfoam","offers":[{"title":"Default Title","offer_id":53531873771887,"sku":"29MIIFRT12","price":88.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/Insulation-SKU_2183980-primary.jpg?v=1790369536","url":"https:\/\/superarbor.io\/products\/insulfoam-r-gard-1-2-in-r-tech-fanfold-insulation-white-2-square-bundle","provider":"Super Arbor","version":"1.0","type":"link"}
