Following the demand and success for its airtightness membranes, Wraptite and Procheck A2, The A. Proctor Group is launching two additions to its range of high-performance A2 fire-resistant membranes.
Probreathe A2 combines breathability, good water resistance, fire resistance and airtightness in one membrane. Probreathe A2 is an airtight woven glass fibre membrane with a PU coating and has a Reaction to Fire classification of A2-s1,d0 when installed free-hanging or on a minimum Class A2,s1d0 substrate, and is suitable for applications over 18m (11m in Scotland). Ideal for use in rainscreen/facade construction, Probreathe A2 is a vapour permeable membrane for use either directly onto sheathing or over insulation.
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).
Another significant benefit of both membranes is that they are robust and durable and serve as temporary protection for the building until the primary external covering can be installed.
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.
