Ubiflex is a non-lead waterproof flashing material which can be used in all applications where lead is traditionally used to provide a weatherproof seam on buildings and roofs in particular. Ubiflex can also be used to form damp proof courses and cavities in masonry walls.

Ubiflex is now available in two types:

  • Ubiflex B2
  • Ubiflex B3
Original Ubiflex has become Ubiflex B3 and a new, lighter version – Ubiflex B2 – has been introduced to the range.
The application selector below shows where Ubiflex B2 and Ubiflex B3 can be used in specific applications. Ubiflex B3 is BBA Certified – the only flexible flashing system with a BBA Certificate.
