TPO Fleece Back FR membranes by Mule-Hide Products Co.
TPO Fleece Back FR membranes are designed for attachment directly to plywood and oriented strand board (OSB) roof decks. They offer a UL Class A fire rating without the need for a fire-retardant barrier board or slip sheet. Fleece reinforcement gives the membrane an added layer of protection against punctures. Splinters from OSB and plywood roof decks will not create holes in the membrane. More puncture-resistant than modified bitumen membranes, the membranes can stand up to hail and damaging debris.
