Mechanically-fastened and ballasted EPDM, TPO and PVC single-ply roof membranes.
Kingspan GreenGuard PB6W Roofing Cover Board is an excellent choice for re-roofing with mechanically attached single-ply membranes. The board’s high compressive strength helps to create a smooth surface, even over most gravel surfaced roofs. The extruded polystyrene (XPS) foam core provides high moisture resistance. PB6W can be used under mechanically attached or loose-laid and ballasted single-ply applications. It is both UL and FM approved. The 50′ fanfold bundles are easy to install and lightweight, adding only 1/10 lb. per sq. ft. With 3 lb. density foam and 3-ply facers that do not delaminate, PB6W delivers solid installed performance.
