Weather strips and seals
Alongside components like warm edge spacers, weather strips protect windows and doors from the elements by sealing the gaps around the frame. Avery Dennison Performance Tapes offers a full line of specially formulated high-performance window seal tape for installing peel-and-stick weather stripping, typically made from EPDM foams. Our double coated, rubber-based scrim tape bonds securely to EPDM foam, offering excellent weather and plasticizer resistance for weather strips and other EPDM foam applications, with low VOC and solvent-free options available for projects where indoor air quality is a specification requirement.
Weather stripping made easy with high-performance tapes
Features
High bond strength and high tack
Good peel and aging resistance, and resistance to plasticizers
Strong dimensional stability
Available in a range of scrim types, from PET to glassfibre to closed glassfibre, for extra barrier properties
Benefits
Easy to apply, no curing time
Strong bonding to EPDM strips that form the seal around door and window frames
Scrim prevents stretching of the strip during application
Long-term resistance to plasticizer migration from the EPDM
Products
FT 666
This a double coated scrim tape with a hotmelt rubber adhesive. The high tack and adhesive coat weight provide strong initial adhesion that is maintained over time on many surfaces. The adhesive works very well on rubber foams with high levels of plasticizer migration, while the polyester scrim reinforcements offer dimensional stability to its carrier.
- Strong bonding to uneven surfaces, with extremely high tack
- Excellent water jet and die cutting characteristics
- Developed for long lasting performance
- Resistant to outdoor weather conditions and plasticizer migration
FT 7984
This is a double coated scrim tape with a hotmelt rubber adhesive. The high tack and adhesive coat weight provide strong initial adhesion that is maintained over time on many surfaces. The adhesive works very well on rubber foams with high levels of plasticizer migration, while the glass fiber (FT 7984, FT 7970) scrim reinforcements offer dimensional stability to its carrier. The FT 7970 tape also offers a polyester film, forming an extra safety barrier. The glassine liners make the products suitable for water jet and die cutting.
- Strong bonding to uneven surfaces, with extremely high tack
- Excellent water jet and die cutting characteristics
- Developed for long lasting performance
- Resistant to outdoor weather conditions and plasticizer migration

Frequently asked questions
-
What's the difference between a weather strip and a weather seal?
In practice the terms are used interchangeably. Both describe the material fitted around a window or door frame to block drafts, moisture and noise; "weather strip" is more common in North America, "weather seal" in Europe.
-
Can weather strip tape handle outdoor temperature swings?
Yes. The adhesive is designed to keep its bond strength across the temperature range a frame sees outdoors, including resistance to the plasticizers that migrate out of EPDM foam over time, so the seal doesn't loosen or lift at the edges.
