W803 – Window & Door Wedge Gasket

W803 wedge gasket is designed to create a reliable seal between the sealed glass unit and the frame. It helps prevent draughts, wind noise and water ingress, improving the overall performance and comfort of your window or door system.

Manufactured from durable, weather-resistant material, this gasket provides long-lasting performance while helping maintain the energy efficiency of your home. Replacing old or damaged gaskets can significantly improve the seal around your windows and doors, making your property warmer, quieter and more energy efficient.

Over time, gaskets can naturally wear out due to exposure and regular use, but replacing them is quick and straightforward. The main challenge is ensuring you select the correct gasket profile for your window or door system. Additional gasket types and lengths are also available to suit different applications.
