3mm Wedge compression back gasket
- This gasket is only available in black.
- SOLD BY THE METRE
Wedge gasket is fitted between the double glazed unit and the upvc frame to hold the glass securely in place. Over time these gaskets can shrink or perish and create gaps which lets in draughts and cold spots. It is important to get the right size of gasket as too thick will put too much pressure on the glass (if you can even get it in) and too thin will not hold the glass tightly. It is more often found on externally beaded windows as it works together with the bead to push the glass into place and create a secure fit.
When fitting wedge gasket you can push into place using your fingers or if you are doing quite a large area you may find a gasket roller better to use. Gasket rollers are available on our site by clicking here
