PROCTOR Probreathe A2 Airtight Membrane & PU Coating - 1.5m x 50m
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 freehanging or onto a substrate which is minimum A2-s1,d0.
Key points :
A2 Reaction to Fire Classification
Increased airtightness over traditional breather membranes
Vapour permeable membrane for use either directly onto sheathing or over insulation.
Ideal for use in rainscreen/facade construction
Suitable for applications over 18m (11m in Scotland)
Robust and durable wall membrane
Allows temporary protection of the building until the primary external covering is installed
Water Vapour Resistance Sd-Value: 0.095m
Reaction to fire: A2-s1, d0
Resistance to air penetration: 0.006m³/(h x m² @ 50Pa)
Probreathe A2 is partially fixed to the sheathing board using Probreathe FR Duo Tape. Horizontal laps should be a minimum 150mm and vertical overlaps should be a minimum 100mm. These are sealed using Probreathe FR Tape.
