PB6 Roof Cover
Product Description
The TopShield PRO® PB6 Roof Cover comprises closed-cell extruded polystyrene (XPS) with high-impact facers on both sides. The board can be installed directly over existing coal tar roof systems if the roof has not been re-saturated within the previous 4 years. The new roof system must be designed to limit the maximum coal tar temperature to 110ºF to prevent volatiles from escaping form the existing system and attacking the TopShield PRO® PB6TS Roofing Cover Board.
