INSULATION IS GREEN

ACFoam CrossVent from Atlas Roofing Corp. is an environmentally friendly polyisocyanurate-foam insulation board for use over sloped, unventilated roof decks. To promote air circulation, the product contains vent spacer strips to separate it from 7/16-inch oriented strand board. Installation can be completed without a thermal barrier directly on the roof deck. (800) 933-1476; www.atlasroofing.com
