PB6 Roofing Cover Board

PB6 Roofing Cover Board header

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 GreenGuard® PB6. With an extruded polystyrene (XPS) core and high-impact polystyrene facers that do no delaminate, this board provides high moisture resistance and resistance to puncture. The 50 ft. fanfold bundles are light weight and easy to install, adding only 1/10 lb. per square foot. The result is a smooth surface, even over most gravel-surfaced roofs.
