Replacing Double Glazed Units

Replacing double glazed units is a home improvement task that can drastically reduce heat loss, improve the insulation of noise and reduce heating bills. Modern coatings and argon/krypton gas filled units make them extremely energy efficient.

The new unit, built to exact measurements, is awaiting its spot. It needs care and accuracy. This is a moment that stops the world and puts your work into perspective.

Then, remove the old unit

Removing the old unit is a crucial step that will help ensure your new double-glazed window is built according to exact measurements.

Preparing the Frame

If you are replacing a fixed or fixed window or a sliding one with a fixed or opening sash, ensure that the new unit is the right size. UPVC frames have a very limited movement and a double-glazed sealed unit that is a few millimeters larger than the original will not fit. To ensure that measurements are accurate make sure you measure with care and seek the advice of a professional.

Remove the glass from the frame after you're sure that the replacement is the right size and has been correctly installed. Wear protective equipment, like gloves and work in a location that is well-lit to avoid injuries from glass shards. Use a putty knife to pry the glazing beads or strips, which secure the glass within the frame, from around the edges of the pane. The glass is hard, and you should be careful not to slip or straining the frame.

When the frame is ready to receive the brand new sealed double glazing unit, check whether it is in a position to open and close easily. You can adjust the fit as needed by removing or adding packing. If the frame is intended for a sliding glass door you may need to add additional packers on the top of the hinge as well as the opposite corner in order to prevent the sash catching when it opens.

Finally, clean up the frame and get rid of any old glazing tape or sealant as required. Check for any damage and make small repairs using wood filler, or sanding if needed. The frame will be rehabilitated with a final cleaning and inspection, allowing it to stand up to the harsh Australian weather for years.

Lifting the New Unit

Over time, double-glazed sealed units (or a sealed unit as it is often called) may face problems like moisture between panes and/or misting. This can compromise the effectiveness of your windows which allows cold air to get in and warm air from your heater to escape, leading to high energy bills and discomfort.

This kind of seal failure is usually the result of aging, general wear and tears or harsh chemical cleaners that damage the sealing material. Sometimes however, the reason can be attributed to the shrinking and expanding of the glass due to temperature changes and seasonal changes.

It is essential to ensure the new unit is properly fitted in the frame prior to locking it to the frame. A little attention during this stage can prevent damage to the frame, as well as the glass.

If your windows use glazing tape or sealant, now is the time to put a bead around the edges of the glass and frame, creating a strong barrier against moisture and air infiltration.

Desiccants also adsorb moisture from the air, preventing condensation and mould in the frame. The spacer bar, typically made of aluminium is also an essential part of the insulation system. Aluminium not only impedes heat transfer but also keeps the edge warm of the window that is insulated to avoid condensation.

Verifying Your Work

It is important that you leave the silicone sealant to cure after you have put in the new unit. It will take at minimum four hours for the silicone sealant to reach its maximum strength and create an impenetrable barrier.
