Wedge gaskets are used to cover the gap between the double glazing unit and the upvc frame to prevent the entry of air, water, dirt or other elements from the environment. They are usually made of materials such as rubber or synthetic elastomers and have a wedge-shaped profile that reduces towards the top. When installed, they are pressed into place to form a tight seal. The wedge-shaped profile is compressed to give the necessary grip and to prevent leaks and drafts from escaping.

These types of draught seals are commonly found in uPVC doors and windows and doors, especially ones with external beading. They are pushed into the channel or groove of the window or doorframe or sash to create a seal, and is easily replaced if they need to be removed for cleaning or repair work.
