Wedge Gaskets

Our rubber wedge gaskets are used during the installation of double-glazed windows and they hold the double-glazed unit in place. The angled edge compresses against the glass and creates a tight seal. When our double-glazing wedge gaskets are fitted externally they act as a window seal and provide weatherproofing benefits. The wedge gasket seal helps to keep water and cold draughts out which can help with energy efficiency. Over time, wedge gaskets can become less effective as a natural consequence of wear-and-tear, so it’s important to replace them on time.

JA Seals stock a variety of wedge gaskets suitable for installing uPVC windows and Smart Aluminium systems. We supply glazing wedge gaskets in a wide range of lengths to suit your requirements. Before choosing a product, make sure you measure the section where the window wedge gasket will be fitted, which is usually the space between the glass and panel. This will ensure the product can fit in the gap while supplying enough compression on the glass.

Our glazing wedge gaskets are easy to install without the need for additional tools or adhesives. Whether you need a wedge gasket for aluminium windows or a wedge gasket for uPVC windows, you’re sure to find something to suit your needs. Browse our range below or contact our team for expert advice!
