uPVC Window & Door Bubble Gasket Seal Flipper Double Glazing Rubber Draught Seal

Most windows and doors are fitted with a rubber gasket seal, designed to create a weather-tight closure between the sash and the frame. This helps to prevent water and draughts from entering. Installation is simple and does not require tools or adhesives—the bubble gasket just clips and pushes neatly into place.

How to Prevent Draughts Around Windows

The most effective way to block draughts is by replacing the existing rubber gasket seal. Over time, older seals can flatten, harden, crack, or shrink, which reduces their ability to provide an effective seal. By fitting a new gasket, you’ll restore a secure barrier that keeps out unwanted air and moisture.
