The new Zip System Radiant Barrier roof panel combines the moisture protection of the Zip System with the energy-efficiency benefits of radiant barrier sheathing. Company testing shows that the panels can help lower attic temperatures by up to 30° and reduce home cooling costs by up to 12%. A 1/2-inch-thick panel costs about $25; 5/8- and 7/16-inch thicknesses are also available. huberwood.com
