Gravel-Surfaced Membranes (Paradiene 20/20 PR)

Non-Surfaced Membrane with Overburden or Gravel Surfacing


Paradiene 20/20 PR is the system of choice for specifications requiring a gravel-surfaced roof membrane.  As with the standard Paradiene 20/30 System, the Paradiene 20/20 PR System utilizes a multi-ply design for weather-tight double protection, combined with the durability and strength of Paradiene 20 PR as the top roofing layer under aggregate surfacings.  The system may be installed using cold adhesive, hot asphalt, or a torch.  To learn more about Paradiene 20/20 PR, click on your preferred application method below.
