    Certificate type

Non-woven fleece laminate with full self-adhesive backing for perimeter sealing of windows and doors.

Jump to:
+44 (0)1942 251400 Website

Application

For the air and watertight but breathable sealing of the internal perimeters of window, door and curtain wall frames in SFS, timber framed, solid and traditional cavity wall or volumetric building type constructions.


Primerless adhesion is usually accomplished on most common construction substrates. The membrane requires consolidation where it is bonded to the substrates. The combination of self-adhesives provides options on the leading edge for installing the membrane to the window frame edge (W orientation) or face (E orientation), providing air, vapour, and weather tightness. ME508 can also be used externally subject to a maximum of 9 months of direct UV exposure. Difficult substrates or cold weather applications may require primer illbruck AT140. Please consult the manufacturers' technical datasheet and method statements.

Description

ME508 Duo EW/F is a non-woven fleece laminate that is self-adhesive on the reverse face, for optimised adhesion to most construction substrates providing airtightness and variable vapour control to the internal window door or curtain wall perimeter joint between the glazed frame and structure. Often used in conjunction with illbruck ME501 Duo HD Membrane usually applied to the external perimeter. 


Features and benefits:

  • Air and vapour tight.
  • Driving rain resistant to 600 Pa.
  • Fully self-adhesive to one face and 20 mm to opposite face, allowing options to fix to window.
  • Avoids use of separately applied adhesives.
  • Can be plastered over.
