Probreathe A2 - Vapour permeable air barrier
Verified by manufacturer 4 months ago
An airtight woven glass fibre membrane with a PU coating.
Application
- Suitable for use in rainscreen/facade construction.
- Suitable for applications over 18 m (11 m in Scotland).
Description
Probreathe® A2 is an airtight woven glass fibre membrane with a PU coating. The membrane combines breathability, good water resistance and airtightness in one membrane. It has a Reaction to Fire classification of A2-s1,d0 when installed free hanging or onto a substrate which is minimum A2,s1,d0.
Features and benefits:
- A2 Reaction to Fire Classification.
- Increased airtightness over traditional breather membranes.
- Vapour permeable membrane for use either directly onto sheathing or over insulation.
- Suitable for use in rainscreen/facade construction.
- Suitable for applications over 18 m (11 m in Scotland).
- Robust and durable wall membrane.
- Allows temporary protection of the building until the primary external covering is installed.
