ME220
EPDM Membrane

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/Purpose

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.

  • High resistance to mechanical damage
  • Excellent movement capability in both transverse and longitudinal direction with excellent material recovery after elongation
  • Excellent weathering, ageing and UV radiation resistance
  • Excellent moisture vapour barrier

Usage Guidelines

ME220 EPDM Membrane is used for weather sealing the exterior side of the connecting joint between a window or façade construction and an adjacent structure (e.g. wall, concrete panel, steel frame, etc.), or to provide an internal airtight barrier in a similar detail.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.
