PermaPly 28

Product Short Description
PermaPly 28 is designed for use as the first or base sheet in built up roofing or modified bitumen roof assemblies.听

Features

PermaPly 28

Features

Meets the requirements of ASTM D 4601, Type II

Lightweight:听Exceptionally pliable, easy to handle and lays flat.

Asphalt Coating:听Makes it suitable as an intermediate or ply felt in cold-applied built-up and modified bitumen roof assemblies.

Ideal for Mechanical Attachment:听Use where mechanical attachment of the membrane to the roof substrate or deck is desired.

Laying Lines:听Laying lines are imprinted on the top surface so the roofing mechanic can install the felt with the proper exposure and provide the correct number of plies.

Surfacing:听Fine mineral parting agent.
