illbruck ME501

ME501 is a high-strength, tear-resistant membrane made from polyethylene copolymer film with non-woven fabric. ME501 is an intelligent membrane providing perimeter joint seal between the window or curtain wall and construction reveal for airtight internal and weathertight external joints..

Standard sizes: Supplied in rolls with widths of 150mm and lengths of 25m. Other sizes on request.

Due to the intelligent, variable vapour permeability (sd value) of ME501, the membrane is suitable for interior and exterior use providing an airtight and weathertight seal whilst always complying with inside tighter than outside principles. It can be applied before or after window installation to suit onsite details and programming.
