FR Breather Membrane Black (ME014) is a vapour permeable polyester, airtight and watertight breather membrane used as a traditional full façade breather membrane.

It is supplied on a 1500 mm x 50 m log and is installed directly over appropriate substrate types such as thermal insulation and sheathing boards to provide weather and UV protection to the built-up wall in closed, open, or partially
open façades.

When installed as a full façade breather membrane over substrates with a minimum Class A2-s1, d0 fire performance, FR Breather Membrane Black (ME014) achieves a Class B-s3,
d0 in accordance with EN 13501-1.

FR Breather Membrane Black (ME014) should be used in conjunction with FR Window Sealing Membrane (ME010) to
seal windows, doors and linear joints.

When used together they form a continuous weather and airtight barrier around the full building envelope including structural openings.

FR Breather Membrane Black (ME014) meets the fire performance requirements for membranes installed on “relevant and higher risk buildings" as defined in
