XFasten Transparent Weather-Sealing Tape – Heavy-Duty Air Leak & Draft Protection (30 Yards)

XFasten Transparent Weather-Sealing Tape is a simple, effective tool for sealing gaps and stopping drafts around windows, doors, vents, and other trouble spots throughout the home. At 30 yards long, it provides excellent coverage for multiple rooms, making it one of the most cost-effective weatherization solutions available.

This tape is fully transparent, blends cleanly with window frames, and forms a durable long-lasting seal that helps prevent warm air from escaping in winter and unwanted heat from entering in summer. It adheres strongly to most surfaces—including wood, vinyl, aluminum, and painted finishes—without leaving residue when removed properly.

For Sustainable Life’s home efficiency approach, weather-sealing tape is a perfect low-cost upgrade that pairs well with heat pumps, smart thermostats, draft stoppers, and window film kits. Reducing air leaks improves comfort, lowers heating and cooling costs, and reduces the load on your home’s HVAC systems—especially during Alberta’s winter months.

Best for:

• Sealing window and door frame gaps

• Reducing air leaks in older homes

• Improving comfort in winter and summer

• Preparing spaces for heat pumps or mini-splits

• Affordable, easy home efficiency upgrades
