WEATHERMATE™ Construction Tape is a strong, pliable, highly adhesive tape for reducing air leakage at joints, seams and other penetrations.

Enhance building envelope resistance to moisture and air intrusion with WEATHERMATE™ Construction Tape over joints and seams of housewraps and insulated sheathing, as well as other penetrations. The tape can also be used to repair damaged foam or housewrap, reducing material costs and job-site waste.

WEATHERMATE™ Construction Tape offers:

  • Strength, durability and impact resistance
  • Excellent tack
  • Application ease
  • Pliability to ensure a tight seal, even at extremely low temperatures
    UV resistance – the oriented polypropylene backing is formulated with a UV-treated film to help resist degradation from exposure to sunlight (WEATHERMATE™ Construction Tape should not be left exposed to sunlight for more than 120 days. Consult your Dow representative for recommendations on protecting other building materials from extended exposure to weather.)
  • Water-resistive barrier – if installing foam as a water-resistive barrier, 2-7/8" tape must be used.

Building Code Compliance

Complies with ASTM D3330 and ASTM D882.
