Description

Dowsil Membrane Dual is an EPDM membrane available in a wide choice of widths that is bonded to substrates using DOWSIL™ 300 Adhesive. Dowsil Membrane Dual provides a weather and airtight seal for fenestration application and can also be used to seal across adjacent building elements.


Features and benefits:

  • Very good mechanical properties.
  • Flexible and tear resistant.
  • Excellent movement capability, thus able to sustain thermal and structural movements of the building.
  • Resistant to UV light, temperature extremes, chemical pollutants and moisture.
  • Available in different widths to enable quick and easy installation.
  • High quality due to use of EPDM raw materials from Dow.
