Self-Sealing Weatherstrips

Durable Self-Sealing Weatherstrips for Fixed Windows


Cooper Standard ISG’s self-sealing weatherstrips are easy to install, locking glass securely in place while providing an effective seal from the elements. And when fixed glass is not an option for your window installation, we also offer a weatherstrip sliding glass assembly that seals just as tightly.


Our self-sealing weatherstrips are flexible and versatile and can be used in a variety of markets and industries for fixed windows applications such as garage door windows, RV windows, automotive windows and heavy farming equipment.
