If this happens, it is important to identify the root of the issue and the steps to take to correct the issue.
Over time, the inert gas that fills the space between the glass panes may escape through cracks or other damage to the unit. This is referred to as a "blown' double glazed unit and in this instance replacing it is the best solution to improve the thermal performance and also to restore the air tight seal that blocks cold air from entering the house.
It is crucial to evaluate the frame's condition before replacing it. If there are indications of damage it should be fixed immediately to prevent further deterioration or potential water leaks. It is also important to ensure that the new sealed unit is the right size for the frame that is currently in place. The UPVC frames have very little tolerance and if the replacement is even a few millimetres too big it will not fit and could be difficult to install properly.
It's a good idea to ask a family member or colleague for help in removing the old unit and then help in putting it on. This will ensure the proper positioning of the glass, and an easy and clean task that will provide the finish you would expect from professionals.
Once the old unit has been removed, it is crucial to clean the entire frame. This will get rid of any residue or dirt and prepare the frame for a new sealant.
After cleaning the frame and glass, it is important to measure the thickness (or another tool) of the sealant. This information will be helpful when deciding on a new sealant unit, since it will require the same thickness in order to fit snugly within the frame.
Removal
Over time, double-glazed windows, also known as sealed units as they are known can fail. They can become misted fog, foggy, steamed-up or cloudy as the air tight seal that separates the two glass panes fails. This allows moisture to get in and result in calcium deposits that could cause stains on the surface of the glass, as well as reducing energy efficiency and allowing cold air to enter your home.
One solution is to replace the double-glazed unit in itself. However, this could be expensive and can be disruptive. A much cheaper and easier option is to replace the gasket seals that are around the edges of the double glazed unit. This will improve the acoustics of your home and energy efficiency, as well as reduce your monthly bills and improve the efficiency of your heating system.

It also will reveal any areas that need attention due to wear or damage. It is essential to address these issues before proceeding with the replacement process, as this could affect the performance of the new window.

It is crucial to take care that the new window is installed correctly and that a high standard of craftsmanship is maintained throughout the process. This is especially important during the sealing phase. It is important to use an adhesive made of silicone that can withstand Australia's diverse weather conditions, and will not crack or break down.
It is important to clean the frame and eliminate any dust and debris prior to installing the new sealed double-glazed unit. Remove any old sealant using an utility knife or putty knife. The frame should be ready to receive the new sealed units. It is recommended to remove the caulking prior to applying the new silicone sealant.
It is crucial to be precise in measuring the height and width of the existing unit. A small error can ruin the fit and lead to additional expenses. To avoid this, measure from multiple points to account for slight variations in the frame.
Once the installation is completed after which it is time to reseal the frame using the silicone caulk. This step isn't just formality, but it's an important step to protect the window's new double glazing against the harsh Australian weather.
Sealing
