The Pemko Q103 Kerf-In Foam Weatherstrip is designed to create a tight, dependable seal along the side of door frames. As a result, it helps reduce drafts and supports better energy efficiency. In addition, it allows smooth door operation with minimal friction.

This Q Series weatherstrip features a soft cell foam core that compresses easily to block air and noise. Furthermore, the foam is enclosed in an embossed, tear-resistant polyethylene cover that is UV-stable and built for long-term use. Because of this durable outer layer, the seal maintains its shape and performance over time.

The product also includes a rigid PVC insert with an extended flange. Therefore, it fits securely into the kerf without nails or adhesives. Not only does this allow fast and simple installation, but it also provides a clean and professional finish.

For proper sealing performance, the minimum space between the door face and the stop should be 3/16″, while the maximum space should not exceed 5/16″. This gap range ensures the foam compresses correctly and maintains an effective seal.
