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
Specification :
Width: 1.5m Length: 50m Weight: 230g/m² Thickness: 0.20mm 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.
