When the glass is removed, it is important to determine its height, width, and thickness. This can be done by removing the glass beads that hold the unit. This is a delicate process that requires patience and prudence. Take your time, and wear safety gear to avoid shards and slips.
The best place to begin is to remove the bottom bead of the glazing strip, with a chisel that is sharp or a an abrasive screwdriver with a wide blade. After the bead is removed, it is recommended to ask for help from someone to hold the sealed unit while you remove the remaining beads. This is because the device could easily be thrown out of the frame and smash.
After removing all beads, it is important to measure the width, the height, and the thickness of the current unit. You can use the measurements to create an appropriate replacement unit. It also serves as a reference to ensure that the new unit is constructed correctly for the frame. It is crucial to ensure that the window fits properly, as a mismatch will not only require the entire unit to be dismantled and reassembled but will also reduce the performance of the unit. This is especially important in Australia where homes are often exposed to extreme weather conditions.
Preparing the Frame

UPVC frames have little room for movement and a double glazing unit that's just a few millimeters larger is likely to not fit. To ensure accurate measurements, measure carefully and consult a professional.

Make sure you work in a well-lit space and wear safety equipment, such as gloves, to avoid injury from glass shards. Utilize a putty knife to cut the glazing beads or strips, which secure the glass within the frame, from around the perimeter of the pane. The glass is fragile and you must be cautious to avoid sliding or pulling the frame.
When the frame is set to receive the brand new sealed double glazing unit, make sure whether it is able to open and close easily. You can adjust the fit by removing or adding packing. For instance, if your frame is a sliding door, you may need to add additional packers at the top of the hinge's side and in the opposite corners to stop the sash from getting caught or shaking when it opens.
Finally, clean the frame and remove any old glazing tape or sealant as required. Assess any imperfections and make minor repairs using wood filler, or sanding if needed. A final cleaning and inspection will prepare the frame for replacement, and will give it a fresh look for long-term protection against the harsh Australian climate.
Lifting the New Unit
Over time, double-glazed sealed units (or a 'sealed unit' as it is commonly called) can develop problems like moisture between panes or misting.

If it's too loose, the unit may be unable to seal its airtight seal. If it's tight enough, it could cause damage to the frame or warp material. Each screw must be put in its original place, and turned to just the right amount to hold the unit securely without putting pressure too high.

The cavity that acts as an insulator between the panes of glass is filled with either argon gas, or a desiccant. Unlike air, argon has less thermal conductivity, which reduces heat transfer through glass. Desiccants also help to absorb moisture from the air, preventing condensation and mould in the frame. The spacer bar that is usually made of aluminium is also an essential component of the insulation system. The aluminium not only prevents heat transfer but also keeps the edges warm of the window insulated to avoid condensation.
Checking Your Work
It is crucial to leave the silicone sealant to set once you have installed the new device. It will take at least 4 hours for it to reach its full strength and create an impervious barrier. While you sit, take the time to visually evaluate your work and see if you can detect any gaps or issues that could compromise the effectiveness or appearance of the product.
