Tremco® 2178

Asphalt-Impregnated Glass Ply Protection Course

Tremco® 2178 Glass Ply Sheet is an asphalt-impregnated fiberglass ply felt marked with laying lines and lightly dusted on one side with a fine mineral parting agent. It features a fiberglass mat with uniform fiber distribution and high tensile strength in both directions.

Basic Uses
  • When fused to the waterproofing membrane, it provides both stability to the membrane and protection during placement of the asphaltic paving overlay.
  • Please refer to the Permaphalt System data sheet for more information.
  • Tremco 2178 may also be used in many other applications where a lightweight, asphalt-impregnated protection course is appropriate.
