Description
GP204P Waterproof Paper
This grade consists of a
sheet of 35# and 30# Kraft
Paper laminated with an 18#
layer of amorphous
polypropylene and
tri-directional fiberglass
reinforcement. This provides
strength, moisture and oil
resistance, and eliminates
any risk of asphalt staining.
It is also lower in cost than
asphalt laminates. 100 yards
