Façade UV & Fire Membrane

ME010 is a water and air tight but vapour permeable polyester based breather membrane in two basic formats highly suited for use as a monolithic breather membrane for sealing around window, door, and curtain wall perimeter tolerance joints (slit into a range of widths), or for sealing sheathing board to board or sheathing board to structure joints (supplied on 1,500 mm x 50 m rolls or in a smaller range of widths). ME010 complies with the reaction to fire classification Class B-s3, d0 according to EN13501-1 when used as a monolithic breather membrane, linear gap or window perimeter membrane seal, in conjunction with SP025 Fire Membrane Adhesive. Class B-s1, d0 achieved.


This high performance breather membrane can be directly laid on sheathing board or thermal insulation behind partially or fully open rain screen façades or curtain walling. ME010 is a highly vapour open, watertight, polyester-based breather membrane, with Class B-s1, d0 to EN13501-1 –including adhesive, tested by MPA Hannover. Suitable for full façade or window perimeter sealing applications.

  • Permanently UV-resistant
  • Class B-s1, d0 to EN13501-1 – fixed to Class A2-s1, d0 mineral wool insulation or sheathing board. Tested with SP025 adhesive as a system
  • High range of in-service temperature resistance
  • Highly vapour-open
  • Non-branded, plain black finish - suitable for visible applications
  • Airtight and weather-tight
  • Available with self-adhesive strip
