Order the full taper layout as a kit so panels and fill pieces arrive cut to the same plan, and keep the D taper (2-1\/2 to 3 in.) consistent with the specified slope. Always confirm the facing type (GRF here) matches the membrane manufacturer's requirements, and follow Atlas installation guidelines with appropriate fasteners or adhesives per the system design.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eConsult local building codes, contract documents, and the membrane manufacturer's installation guidelines before installing tapered roof insulation.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eBuild positive drainage into your low-slope roof with Atlas ACFoam-II tapered polyiso insulation panels.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Atlas","offers":[{"title":"Default Title","offer_id":53529539477871,"sku":"TP2_012","price":40.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/12670_default_hero.jpg?v=1790351206","url":"https:\/\/superarbor.io\/products\/atlas-tp2-012-atlas-acfoam-ii-4-ft-x-4-ft-tapered-polyiso-roof-insulation-panel-d-taper-2-1-2-in-to-3-in","provider":"Super Arbor","version":"1.0","type":"link"}
