Tremco DualFlex

Flashing Material for Hot-Applied Waterproofing Membranes

Tremco DualFlex® is a reinforcing flashing that consists of a central strip of elastomeric SEBS rubber flanked on either side by an absorbent non-woven felt. The felt allows for easy integration of the flashing and the waterproofing membrane. The elastomeric SEBS rubber provides superior movement capability without compromising the waterproofing.


  • Tremco DualFlex is used as a flashing material at joints, transitions in plane, horizontal-to-vertical transitions and any other situation in waterproofing where durable, reinforcing sheeting is desired
  • Tremco DualFlex is ideal for use with TREMproof® hot-applied waterproofing membranes and Vulkem® deck coating basecoats
