Sealing of external glazed frame perimeters. Sealing of other linear joints such as at the head and foot of sheathing boards at the slab edge or against columns and abutments.

Some restrictions apply to the application of ME010 Façade UV & Fire Membrane at low level thresholds. No such restrictions apply to punched whole window applications. Please consult illbruck CPG-UK Ltd Specification Manager for further guidance. Please note that interfaces with third party waterproofing layers laid over low thresholds, walkways and podiums will result in an unavoidable diminished reaction to fire. This is due to the default inability of the likely backing substrate to achieve the minimum required reaction to fire of class B-s3,d0. A variation in the bonding adhesive may be necessary to ensure compatibility.


Applied as a system in conjunction with illbruck SP025 Fire Membrane Adhesive. The membrane is applied to the external perimeter of glazed frames lapped and sealed to the backing wall for a secure and robust seal. The membrane and adhesive combination achieves a Class B-s1,d0 Reaction to Fire according to BS EN 13501-1 and 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 the full sized breather membrane variant ME010 Facade UV & Fire Breather Membrane to provide a fully compatible and integrated building protection wrap around the external backing wall in a framed and sheathed construction.

Features and benefits:

  • Permanently UV-resistant.
  • Euroclass B-s3, d0 to BS EN 13501-1.
  • B-s1, d0 when tested as a system with SP025 Adhesive.
  • High range of in-service temperature resistance.
  • Highly vapour open.
  • Non-branded, plain black finish - particularly suitable for visible applications.
  • Airtight and weather tight.
  • Available with self-adhesive strip.

Is used in conjunction with:

  • Please note: In order to meet Class B-s3, d0 to EN 13501-1, SP025 must be used.
