Frequently Asked Questions:

How do I know if I need to replace my window or door gasket?
Signs include noticeable draughts, increased condensation, water ingress, or visible deterioration of the existing seal. If your current gasket appears cracked, shrunk, or hardened, it's time for replacement.

Will this gasket fit my specific uPVC windows?
This gasket is designed to fit most standard uPVC window and door frames. The arrowhead design is offset from centre, allowing you to insert it either way to achieve the best seal for your specific groove width (between 3.2-4mm).

Do I need special tools for installation?
No special tools are required. You'll only need a pair of scissors to cut the gasket to length and possibly a flat-headed screwdriver to help remove the old seal.

What if my window frame is warped or has uneven gaps?
For frames with uneven gaps or warping, we recommend additionally using Stormguard Self-Adhesive Extra Thick Memory Seal (tolerance 3mm-8mm) on problem areas to ensure a complete seal.

How long will the gasket last once installed?
With proper installation, this high-quality TPE gasket should last several years under normal conditions. Longevity will depend on exposure to extreme weather, sunlight, and frequency of window/door operation.
