E-gaskets and fir tree gaskets are replacement seals used in uPVC window and door systems. Fir tree profiles have a shaped base that grips into a groove in the frame, helping to keep the seal in place.
A correctly fitted replacement can help reduce draughts around your windows and doors. Our range includes popular profiles for single repairs and larger refurbishment projects.
Gaskets are available in black and white, depending on the profile. Compare the shape and dimensions of your existing seal with the product details before ordering.
If you’re unsure which profile you need, our gasket sample pack lets you try the seals in your frame before buying a full length.
