FR Window & Door Sealing Membrane (ME010) is a Class B-s1, d0, permanently UV resistant, high strength polyester, airtight and fully watertight membrane used as a perimeter membrane seal to the external side of glazed units such as windows and doors. When correctly installed with illbruck FR Membrane Adhesive (SP025), it provides an air and fully watertight seal over the construction joint which remains breathable to enable any trapped incidental moisture or condensation to escape out through to the external side of the wall construction. It can also be used to seal and protect horizontal and vertical linear joints between sheathing boards and the main structure.


FR Window & Door Sealing Membrane (ME010) meets the fire performance requirements for membranes installed on “relevant and higher risk” building types as defined in Approved Document B of the Building Regulations for England and Wales.


It is available in 50 m rolls with a range of pre-cut slit widths from 60 mm to 400 mm wide and when installed over compatible substrates with a minimum Class A2-s1, d0 fire performance provides a Class B-s1, d0 fire performance in accordance with EN 13501-1.


When tested for water resistance in accordance with EN 1928 with a 2 kPa head of water, FR Window & Door Sealing Membrane (ME010) achieves the criteria for Class W1 in accordance with EN 13859-2 and also remains watertight when tested over for an extended 24 hours test duration.


Illbruck’s FR Window & Door Sealing Membrane (ME010) should be bonded back to the frame and substrate using illbruck FR Membrane Adhesive (SP025) and can be used in combination with a compatible illbruck FR Breather Membrane to provide a full façade solution. When used together they form a continuous weather and airtight barrier around the full building envelope including structural openings.


It is important that FR Window & Door Sealing Membrane HD (ME007) is installed in the correct orientation with the smooth/coated side always facing outwards towards the external environment.
