Keep joints tight but not forced, stagger board joints from the insulation below, and adhere or fasten per the membrane manufacturer's specification. Order cover board at the same thickness the assembly was designed for; stepping thicknesses changes R-value and drainage.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eHandle large rigid foam boards carefully on windy rooftops to prevent them from being lifted or broken, and follow fastening and fire-safety requirements for the roof assembly.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eOrder Mule-Hide Poly ISO1-HD 1\/2 in. cover board sheets for a tougher membrane substrate.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Mule-Hide Products","offers":[{"title":"Default Title","offer_id":67583082463599,"sku":"58MHHD0548","price":45.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/Insulation-SKU_2277967-primary.png?v=1790405644","url":"https:\/\/superarbor.io\/products\/mule-hide-poly-iso1-hd-1-2-in-polyiso-roof-cover-board-4-ft-x-8-ft","provider":"Super Arbor","version":"1.0","type":"link"}
