Bubble Gaskets
Bubble gaskets are commonly used to create a reliable watertight seal in uPVC windows and frames. They are named for their distinctive bubble-shaped profile that compresses when the window or door is closed. Over time your existing section may have shrunk, torn or become less effective at keeping your home warm and comfortable. Replacing these sections is essential to prevent water ingress and energy loss, contributing to the overall thermal efficiency of your home.
We recommend that you carefully measure the shape of your existing section before identifying the best replacement product. You'll need to measure the size of the round bubble and arrow foot on your current seal to make sure that you purchase a replacement section that fits in the window frame.
Installing a new bubble gasket is a relatively simple process that does not require technical knowledge or support. The section can be pushed into the groove around the frame using your fingers and thumb. As the arrow foot holds the section tightly in the channel, you do not need to bond the seal in place with any sealant or adhesive.
