Why Replace a Double Glazed Sealed Unit?
If you replace the double-glazed seal, you're doing more than repairing the broken window. You're improving the health and energy efficiency of your home.
Ensure your work is done correctly and you'll be able to enjoy years of comfort and savings. It is important to take the time to prepare and check the frame.
Preparation
Double-glazed units are also referred to as sealed units and are a vital element of any Australian home. They improve comfort and energy efficiency, offer security and lower noise levels by forming an insulation barrier between the indoors and outside world. As time passes, they may start to fail. It is important to know the reason for this and then fix it.
In time, the inert gases that fill the space between glass panes can escape from the unit through cracks or breakage. This is a blow double glazed unit. In this situation it is recommended to replace the unit to repair the thermal performance and airtight seal to prevent cold winds from entering the home.
During the replacement process it is crucial to examine the frame's condition and ensure it is in good working order. If there are indications of damage it should be fixed immediately to prevent further damage or water leaks. It is also essential to make sure that the sealed unit is of the correct size for the existing frame. The UPVC frames have very little tolerance and if the replacement is even a few millimetres too big it will not fit and will be difficult to put in the right way.
It's a good idea to ask a friend or colleague for assistance in getting rid of the old one, and then to assist with installing the new one. This will ensure the proper positioning of the glass, and an easy and neat job that will give the finish you would expect from an experienced professional.
After the old unit has been removed, it is crucial to clean the entire frame. This will remove any dirt or residue and prepare the frame for the application of a new sealant.
After cleaning the frame and glass, it's important to measure the thickness (or another tool) of the sealant. This is important to know when purchasing a replacement sealant as this will need to be the same thickness to ensure a perfect fit into the frame.
Removal
Over time, double-glazed windows, also known as sealed units as they are known, may fail. When the airtight seal that is used to seal two panes of glass fails, they can become cloudy, misty, steamed or cloudy. This allows moisture into the home, which can cause calcium deposits that may cause stains on your glass. Also, it reduces efficiency and also allows cold air to get in.
One way to resolve this is to replace the double glazed unit itself. However, this could be costly and can be disruptive. A much cheaper and easier alternative is to replace the gasket seals on the edges of the double glazed unit. This will increase the efficiency of your heating system as well as reduce the cost of energy and improve the acoustics your home.

It will also identify any areas of damage or wear that require attention. It is important to address these before continuing with the replacement process, as this could affect the performance of the new window.
To clean the frame use a paint brush to clean any debris or dirt the edges of the frame. You should also check the frame for signs of damage or rot that require attention. This is an essential step to ensure the integrity of your house and ensure that the replacement double glazing is functioning exactly as it should.

Over time, double glazing units or sealed units as they are commonly called may fail. This is most commonly due to a problem with the air-tight seal around the edges of the two glass panes. This allows the inert gas argon to escape out of the window, which is designed to be insulating. This is a bad thing as it reduces the thermal performance of the windows, thereby increasing heating costs significantly. Double glazing will increase the insulation in your home, and will reduce the cost of energy.
The assessment of the extent of damage is the first step to replace an item that is sealed. A thorough inspection will reveal problems such as chips, cracks or fogging between the panes of glass, as in addition to damage to the frame and seals. This will determine if a complete replacement is needed or if other repair options are available.

Care must be taken to ensure that the window is properly installed and a high standard of workmanship is maintained throughout the process. This is particularly important when sealing the window. It is crucial to select a silicone sealant that can withstand Australia's diverse weather conditions, and will not crack or break down.
Before installing the new double glazed sealed unit, it is vital to make sure the frame is clean and free of dirt and dust. A utility knife and a putty knife should be used to eliminate any old sealant and ensure that the frame is ready for the new sealed unit. Before applying the new silicone sealant, it is a good idea apply caulking remover.
It is important to be precise in measuring the height and width of the unit that is currently in use. A tiny error could ruin the fit and lead to additional expenses. To avoid this, take measurements from several points to account for any slight variations in the frame.
Once the installation is completed after which it is time to seal the frame with a silicone caulk. This isn't only a formality, but it's crucial to shield the new double-glazed window from the various weather conditions in Australia.
Sealing
Double glazing helps keep your home warm during winter and cooler during summer by adding an extra layer of insulation that contains the inert Argon. As time passes, the sealed units (also called glazed units) could fail, causing the insulating gas to leak out.
