Product Description

Wakaflex® is a lead free, flexible, adhesive flashing designed to replace lead in most modern roofing applications.

The product has many advantages over traditional lead flashings for those working in the construction industry, including the simple and quick installation process and non-toxic, lightweight material.

Easy application through high stretchability in both directions of the material and has a unique product composition with a self-welding effect.

Width: 280mm.
Weight: 10.4kg.
Maximum pitch: 90°.

  • Laps should be not less than 50mm using a roller to apply pressure.
