Spray foam insulation used on to The underside on the decking will void the guarantee. Atlas shingles can be put in above a roof process made up of a radiant barrier substance if: one. the expected total, move through air flow is maintained specifically underneath the decking material in all instances, two. the radiant barrier substance is very vapor permeable ( > two perms), and, three. the radiant barrier is set up over the underside of or under the decking – not used as an underlayment previously mentioned the decking. Spray-Ââ€on sorts of under deck vapor permeable radiant barriers will be thought of only over a task by position basis, and provided that checks confirm > two perms or larger vapor permeability.
Atlas very suggests using higher overall performance, ASTM 6757 compliant - Gorilla Guard® Everfeltâ„¢ or Summit® proprietary underlayment solutions for long run roof technique performance and WeatherMaster® items self-Âadhering, waterproofing underlayment for vital parts, which include valleys and eaves.
