Probreathe A2 Air is a woven glass fibre membrane designed to provide the building fabric with excellent water resistance and breathability. Suitable for use in rainscreen/facade construction, Probreathe A2 Air is both air and vapour permeable and is designed for use either directly onto sheathing or over insulation. Probreathe A2 Air has a Reaction to Fire classification of A2-s1,d0, and is suitable for applications over 18m (11m in Scotland).
As buildings become increasingly better insulated and more airtight, moisture management at the design stage becomes critical. The introduction of the Probreathe A2 Air and Probreathe A2 membranes will improve energy efficiency and reduce the risk of condensation within residential and commercial buildings.
