uPVC Window & Door Bubble Gasket Rubber Seal

Improve the seal around your windows and doors with this uPVC Bubble Gasket Rubber Seal, designed to replace worn, damaged, flattened or perished weather seals.

The flexible bubble profile compresses when the window or door is closed, helping to create a tighter barrier between the frame and opening. This can help reduce draughts, minimise gaps and improve protection against external weather, while also providing a neat replacement for ageing gasket seals.

Designed for compatible uPVC window and door frames, the gasket pushes into the appropriate frame groove for a secure fit. Its flexible rubber construction makes it suitable for replacement, repair and refurbishment projects around the home.
