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