Following its airtightness membranes, Wraptite and Procheck A2, The A. Proctor Group is launching two additions to its range of A2 fire-resistant membranes.
Probreathe A2 combines breathability, good water resistance, fire resistance and airtightness in one membrane. It 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).
Probreathe A2 Air is a woven glass fibre membrane designed to provide the building fabric with 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).
Both membranes can serve as temporary protection for the building until the primary external covering can be installed.
