Usage/Purpose

ME501 is a high strength, tear resistant membrane made from polyethylene copolymer film with woven fabric. It can be applied before or after window installation to suit on-site details and programming. It is also available with gasket options for fixing to profile.

The product meets the recommendations of the RAL Quality Assurance Association for windows and doors. Successfully tested by MPA Hannover to EN1026 (airtightness) & EN1027 (weather tightness). The membrane is attached to the window with SP525 adhesive or gasket and to the construction reveal material with SP525 adhesive.

  • Complies with principle of ‘inside tighter than outside’ in order to facilitate efficient vapour control
  • Excellent drying potential (due to the membrane’s breathability) avoiding mould growth and physical damage
  • UV stable - will tolerate up to 9 months direct exposure prior to covering

Usage Guidelines

Provides a high performance seal to the perimeter joint between the window/curtain wall and the construction reveal.

Due to the variable sd-value, the membrane is suitable for interior and exterior use and can provide an airtight or weathertight (but breathable) seal.
