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.
