PB6 Roofing Cover Board

For use with mechanically-fastened and ballasted EPDM and TPO single-ply roof membranes.

When you need to re-roof, nothing works better as a cover board than the GreenGuard® PB6 line of products. With an extruded polystyrene (XPS) core and high-impact polystyrene facers that do not delaminate, this board provides high moisture resistance and resistance to puncture. The 50 ft. fanfold bundles are lightweight and easy to install, adding only 1/10 lb. per square foot. The result is a smooth surface, even over most gravel-surfaced roofs.
