FR Breather Membrane WHITE (ME055) - Breather Membrane
Verified by manufacturer 6 months ago
A bonafide non-combustible air and vapour permeable breather membrane suitable for enclosed masonry clad facades or for use as a base layer in a rainscreen façade applied directly to the backing wall.
Application
ME055 is suitable for:
- Use in new builds and in refurbishment projects.
- Enclosed façades e.g. masonry, decorative cement panels, rock panel or similar.
- Application within high rise buildings, timber frame construction, public buildings and off-site construction.
- As a base layer in a rainscreen façade applied directly to the backing wall.
ME055 is typically over sheathing boards or other substrates with a reaction to fire of at least Class A2-s1,d0. The overlapping seams and perimeter edges are sealed with illbruck ME356 FR Sealing Tape. In addition, illbruck SP025 Fire Membrane Adhesive may also be used to provide an enhanced air and water-tight connection to adjacent walls and floor junctions.
Description
illbruck ME055 FR Breather Membrane is a monolithic glass fibre-reinforced breather membrane that achieves a Class A1 Reaction to Fire according to BS EN 13501-1. ME055 is highly suited to applications in buildings that have been classified as "Relevant Buildings" as defined in Approved Document B, April 2019. Often used in conjunction with other illbruck slit-to-width interface sealing membranes at window and door openings or other linear joints to provide fully compatible and integrated building protection wrap around the external backing wall in a framed and sheathed construction.
Features and benefits:
- Easy to cut and install.
- Permanently UV-resistant behind partly open façades or three months prior to cladding.
- Wind and driving rain resistant.
- High temperature resistance.
- W2 water resistance.
- Classified as a breather membrane with an Sd value of 0.03 m.
- Class A1 Reaction to Fire according to BS EN 13501-1.
- Supplied on rolls of 1.5 x 35 m.

Execution | Manufacturer guidanceillbruck ME055 A1 Breather Membrane (White), W2 is unfurled and applied directly from the log to the substrates. The membrane is secured with tape to the structure and overlapping seams to create a homogenous and continuous protection layer. Applications should start from the bottom of the building and work upwards overlapping subsequent horizontal and vertical layers by a minimum of 100 mm. Perimeters and overlapping seams are sealed with illbruck ME355 FR Sealing & Joining Tape A2 or other tape specified by illbruck. Some details e.g. floor junction or solid walls may require the use of illbruck SP025 Fire Membrane Adhesive in addition to the illbruck ME355 FR Sealing & Joining Tape A2. |
