Wedge gaskets are designed to be inserted between the glass and frame on uPVC windows and doors. The tapered edge applies compression against the glass to hold the window tightly in place and create a reliable watertight seal. Over time these seals begin to perish, shrink and become less effective so should be replaced to maintain a watertight and draft free home. They can be used on uPVC and composite windows and doors in residential and commercial buildings.
To identify the best replacement section you will need to carefully measure the gap where the seal will be fitted. This will usually be the gap between the glass and panel. It is essential to purchase the correct product to ensure that the replacement seal is large enough to put enough compression onto the glass but is not too big to be fitted into the available gap.
The installation of a new wedge gasket is a relatively straightforward process. These sections can be pressed into the glazing channel around the perimeter of the frame by hand and do not require any adhesive. The flexibility of the material allows for a degree of movement, accommodating the natural expansion and contraction of the frame and glass caused by temperature fluctuations.
