Description
ME220 EPDM membrane is used for weather sealing the connecting joint between a window or a façade & an adjacent structure, or to provide an internal air-tight barrier in a similar detail.
Usage
If an internal and external membrane is required, in order to meet the principle of ‘inside tighter than outside’, ME220 should be located as the inner membrane and ME501 Duo Window Membrane HD as the outer membrane. This will ensure that the inner seal is more vapour tight than the outer which will facilitate drying out of any entrapped moisture between the two layers.
