MB sheet for use in New or Replacement Roofing Systems

Developed specifically for use in Canada, the POWERply 3PM membrane is designed to be mopped in place in a two ply new or replacement roofing system over an approved base ply.  It may also be used as the finishing ply when assembling a more conventional multi-ply roofing membrane. 


POWERply 3PM is a prefabricated, granule surfaced weathering membrane consisting of a non-woven polyester reinforcement that is fully coated with an SBS modified bitumen. The top surface is covered with ceramic granules to provide a prefinished surface and weather protection. The underside is sanded to permit adhering to a variety of surfaces and to ensure ease of
unrolling during application.
