Paradiene 20 is the first ply of Paradiene 20/30 Systems. The base ply is an elastomeric asphalt blend reinforced with a fiberglass mat that absorbs roof stresses, while the granule-surfaced top ply, Paradiene 30 or Parafor 30, shields the base from the elements and mechanical abuse. These high-performance modified bitumen base plies can be applied in approved Type III or Type IV asphalt, PA-1000 Polymer Asphalt, Siplast PA-311 Adhesives, or SFT Adhesive.
