BBA Agrément Certificate
Certificate type
A highly breathable membrane with multi-layer polypropylene (PP) construction offering water resistance, UV stability, and flexibility at low temperatures.
Application
Suitable for use on both the internal and external sides of the building envelope. Used as a breathable membrane in construction to provide water resistance while allowing water vapour to pass through, suitable for use in building envelopes and roofing systems.
Description
Traspir 150 is a highly breathable membrane composed of three layers: a top layer of non-woven PP fabric, a middle layer of PP breathable film, and a bottom layer of non-woven PP fabric.
Features and benefits:
- Available with or without integrated tape.
- 1.5 m and 3 m length options.
- BBA certified.
