Replacing Double Glazed Units

Replacing double glazed units is a project for home improvement which can significantly reduce heat loss, improve insulation from noise and reduce heating bills. Modern coatings and argon/krypton gas-filled units make them extremely energy efficient.

Remove the Old Unit

Removing the old unit is a crucial step to ensure your new double-glazed window is built to precise measurements. Clean the frame carefully to remove dust, dirt or old sealant.

Once the glass is removed, it is important to determine its width, height and thickness. This can be accomplished by removing the glass beads that hold the unit. This is a delicate process that requires patience and prudence. It is recommended to take your time and always wear safety equipment to protect yourself from unexpected shards of glass and accidental slips.

Begin by removing the lower part of the glazing strip with a sharp chisel, or a wide-bladed, sharp screwdriver. It is best to ask someone else to hold the window unit while you remove all the beads. This is because the device could easily fall out of the frame and hit.

Remove the glass from the frame once you're certain that the replacement is the right size and has been properly fitted. Be sure to work in a well-lit area, and wear safety equipment such as gloves to avoid injuries from glass shards. Use a putty knife to cut the glazing strips or beads, which secure the glass to the frame, starting from around the perimeter of the pane. The glass is brittle, and you should be cautious to avoid sliding or pulling the frame.

Verify that the frame will open and close smoothly when the new sealed double-glazing unit is installed.

For instance, if your frame is a sliding door, you may have to add packers at the top of the hinge side and opposite corner to keep the sash from catching or rattle when it opens.

Finally, clean up the frame and take off any old glaze tape or sealant as required. Assess any damage and make small repairs by using wood filler or sanding if necessary. A final inspection and cleaning will prepare the frame for replacement, rejuvenating it for a lifetime of enduring protection against the harsh Australian climate.

Lifting the New Unit

Over time, double-glazed sealed units (or a 'sealed unit' as it is often called) may face issues like moisture between panes or misting. This can reduce the efficiency of your windows which allows cold air to enter and warm air from your heater to escape, which can result in uncomfortable energy bills and discomfort.

The insulating cavity between the panes of glass is filled either argon gas or desiccant. Unlike air, argon has less thermal conductivity, which reduces heat transfer through the glass. Desiccants also help to absorb moisture from the air, which prevents condensation and mould in the frame. The spacer bar, which is typically made of aluminium is also an essential part of the insulation system. The aluminum bar not only blocks heat transfer, but also keeps the edges warm of the window insulated to avoid condensation.
