Frequently Asked Questions

Q: What type of windows is this TPE window seal strip compatible with?

A: This flexible bilateral window seal strip is designed for plastic-steel (UPVC) window frames and door frames that feature a card slot channel. The clip-in design means it simply presses into the groove without adhesives or tools, making it ideal for standard UPVC residential windows and doors.

Q: How does the card slot installation work?

A: The strip features a card slot profile that clips directly into the channel groove found on most plastic-steel (UPVC) window and door frames. Just align the strip with the slot and press it in firmly — no glue, tape, or specialist tools required. It stays securely in place thanks to the flexible TPE material and high-rebound construction.

Q: How much coverage does one roll provide, and can I cut it to size?

A: Each roll provides up to 4 metres of seal strip, offering generous coverage for multiple windows or an entire door frame. The TPE material can be easily cut with standard scissors or a utility knife to achieve the exact length you need for a neat, precise fit.

Q: Is the seal strip durable for long-term use?

A: Yes. The high-rebound TPE foam core compresses when the window or door closes and rapidly returns to its original shape when opened, maintaining an effective seal over thousands of open/close cycles. The material is also resistant to temperature fluctuations, UV exposure, and everyday wear, ensuring reliable performance season after season.
