Once you have a clear idea of the dimensions of your replacement, and are confident that it's fitted correctly, remove the glass from its frame. Wear protective equipment, such as gloves and work in a place that is well-lit to prevent injury from glass shards. Utilize a putty knife to remove the glazing strips or beads that secure the glass to the frame, starting from around the perimeter of the pane. It is important to avoid slipping the glass or straining frame.
Make sure the frame can be opened and closed smoothly after the double-glazing unit that is sealed is installed. It should be a snug fit, but you are able to adjust this if necessary by removing or adding packers. If the frame is intended for sliding glass doors, you might need to add packers on the top of the hinge and opposite corner in order to prevent the sash from being caught when it opens.
Then clean the frame. Take off any old glazing tape or sealant, if necessary. Check for any damage, and make minor repairs, if needed, using wood filler or sanding. A final clean and inspection will prepare the frame for your replacement, rejuvenating it for an extended period of protection against Australia's harsh climate.
Lifting the New Unit
