Preparing the Frame

When the frame is ready for the new sealed double glazing unit, ensure that it is able to open and close smoothly. You can alter the fit if needed by adding or removing packing. If the frame is designed for sliding glass doors you may need to add packers to the top of the hinge and opposite corner to avoid the sash from being caught when it opens.

Then, clean the frame. Take off any old glazing tape or sealant If needed. Check for any damage, and make small repairs if necessary by using wood filler or sanding.
