Description

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.

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

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.
