About this item
- 0.5mm Heavy Duty Window Insulation Tape: Made with a robust 0.5mm thickness – approximately 2.5X thicker than ordinary 0.2mm tapes. This heavy-duty window insulation tape offers superior tear resistance, reliable draught proofing, and long-lasting performance. Ideal for sealing windows exposed to cold weather and strong winds.
- Blocks Cold Air, Draughts & Heat Loss: Designed for homes affected by draughty windows and winter weather. This window sealing tape helps seal window frames and sills, preventing cold air infiltration and reducing heat loss. Keep indoor spaces warmer and more comfortable throughout the colder months.
- Residue-Free Removal: Removes cleanly when winter is over. Our transparent window seal tape is designed for easy removal. For best results, gently warm the tape with a hair dryer before removal and peel it off slowly. This helps minimize the risk of damage to painted surfaces, walls, or finishes, especially after extended use.
- Strong Adhesive for Year-Round Protection: Featuring a strong adhesive backing that remains effective in hot summers and cold winters. Resistant to moisture, UV exposure, and temperature changes. Use as a window insulation tape in winter or as a window AC sealing tape in summer to help block unwanted air leaks.
- 50mm Wide Coverage for Multiple Applications: The 50mm (2-inch) width provides enhanced sealing coverage for uneven gaps and surfaces. Perfect for windows, window AC units, portable air conditioners, doors, bathrooms, and basements. Helps block draughts, moisture, and hot air while improving indoor comfort and energy efficiency.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
