These tools are beneficial to glaziers as they permit them to push the spline flat of the gasket into the window groove without using a ladder. These tools are available in various sizes, and some even have a pointed tip that can be used to push the gasket into difficult corners. This can cut down on the time required to install windows and can also be employed to ensure that the gasket is in line with the frame of the window.

Wedge Gasket

Wedge gaskets cover the gap between the double glazing window seal repair glazing unit and the upvc frame and prevent the ingress of air, water dirt or other environmental elements. They are usually made of synthetic elastomers or rubber, and feature a wedge-shaped profile that narrows towards the end. When they are installed they are then put into place to form an elastomeric seal. The wedge-shaped profile gives it a solid hold, and prevents leaks and drafts from escaping.

These types of draught seals are commonly found in uPVC doors and windows, particularly ones with external beading. They are pushed into the groove or channel of the doorframe, window or sash frame to create an airtight seal. They can be easily changed if they need to removed for cleaning or repairs.
