H-Shield is a rigid roof insulation board with a closed-cell polyisocyanurate foam core bonded to fiber-reinforced facers on both sides. It comes in thicknesses from 1 inch to 4.5 inches, with R-values from 5.7 up to 26.8, so one product line covers low-slope roof decks needing anything from a thin recovery layer to a high-R assembly. It suits roofing contractors and builders insulating flat or low-slope roofs, where its high R-value per inch lets a thinner board hit a target than mineral wool or fiberglass board. Against those rivals it is lighter and stiffer, but polyiso loses R-value in cold weather and needs a cover board or careful handling under traffic.
