Preparation

Double-glazed units are also known as sealed window repair units and are an essential component of any Australian house. They help to increase comfort and energy efficiency, offer security and lower noise levels by forming an insulating wall between the indoors and outside world. Over time, they can start to fail. It is important to know the cause and the best way to repair it.

Over time the inert gas that fills the space between the glass panes can 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 will be the best solution to improve the thermal performance and also to restore the air tight fridge seal Repairs that stops cold air from escaping into the home.

It is important to assess the frame's condition prior replacing seal on windows it. It is crucial to fix any damage as soon as it occurs in order to avoid further deterioration and leaks of water. It is crucial to make sure that the new sealed unit is compatible with the frame you have. The UPVC frames are extremely rigid and if you replace them with something even a few millimetres bigger the frame will not fit and be difficult to install.

It's a great idea to ask a friend or colleague for help in removing the old unit and then assist with installing the new one. This will ensure the proper positioning of the glass, and an easy and clean task that will provide the look you'd expect from a professional.

After the old unit has been removed, it is crucial to wash the entire surface of the frame. This will remove any traces of residue or dirt, prepare the frame for new sealant and ensure that it is ready for a fresh installation of the new unit.

After cleaning the frame and glass, it is essential to determine the thickness (or other instrument) of the sealant. This information will be helpful when ordering a new sealed unit, as it will need to have the same thickness to fit comfortably inside the frame.

Removal

Over time, double-glazed windows or sealed units as they are known can fail. They may become misty or foggy, steamed up or cloudy when the air tight seal that separates the two glass panes fails. This allows moisture to get in and cause calcium deposits to cause stains on the glass's surface, as well as reducing energy efficiency and allowing cold air to enter your home.

One option to solve this is to replace the double glazed unit within the unit itself. However, this could be costly and can be disruptive. An alternative that is less costly and more convenient alternative is to replace the gasket seals around the edges of the double glazed unit. This will restore thermal efficiency as well as reduce the cost of energy and improve the acoustics your home.

You'll need to take the old unit from the uPVC frames. This is an unpleasant and risky job however, with careful thought and the right tools you can safely take off the existing glass and be left with an empty frame that is ready for the new sealant.

After removing the old unit, it is a great idea to thoroughly clean the uPVC frames. This will create a clean surface on which the new sealant can stick. This will also reveal any areas that require attention due to wear or damage. It is important to address these before continuing with the replacement process as this will impact the performance of the new window.

Use a paintbrush to remove debris and dirt from the frame's edges. Check the frame for signs of rot or damages that require attention. This is an important step to ensure the integrity of your home and ensure that your replacement double glazing is functioning as it should.

Installation

Over time, double glazing units or sealed units as they are often called, can fail. The majority of the time, this happens due to a breach in the airtight seal that is around the edges of the two panes. This allows the inert gas argon to escape from the window, which is designed to be insulating. This is not a good thing as it reduces the thermal efficiency of the windows, thereby increasing heating costs substantially. Double glazing will improve the insulation in your home and reduce the cost of energy.

Assessing the extent of the damage is the first step in replacing a sealed unit. A careful inspection can identify problems such as chips, cracks or fogging between the panes glass as well as damage to the frame and seals. This will help determine whether replacement is needed or if other repair options are possible.

Once the assessment is complete the removal process can begin. Care must be taken to ensure that the window is correctly installed and a high standard of workmanship is maintained at all times. This is especially important during the sealing phase. It is crucial to select the right sealant made of silicone, which can withstand Australia’s diverse weather conditions and will not break or become brittle.

It is crucial to clean the frame and get rid of any dust and debris prior to installing the new sealed double-glazed unit. Remove any old sealant with an utility knife or putty knife. The frame should be ready to receive the new sealed units. Before applying the new silicone sealant it is a good idea to employing a caulking remover.

It is important to precisely measure the height and width of the unit that is currently in use. This is because a slight error can cause a problem with the design of an entirely new unit, and result in extra expenses. To avoid this, take measurements from several points to account for slight variations in the frame.

After installation, you'll need to seal your frame using silicone caulk. This isn't only a formality, but it's important to protect the window's new double-glazed design from the various weather conditions in Australia.

Sealing

Double glazing is designed to help keep your home cooler during summer and warmer in the winter months by providing an additional layer of insulation, which contains the inert Argon gas. However, over time, the sealed units (also called glazed units) may fail, and cause the gas that is used to insulate leak out. The signs of this may vary but usually include a hazy appearance to the glass or a draught inside your home.

After removing the seal, the next step is to accurately measure the length, width and height of the existing unit. This will ensure that the replacement is made according to the correct measurements, and so it can provide a high quality and effective degree of insulation.

Once the replacement sealed unit is correctly measured, the next step is to apply the new sealant made of silicone. This is a crucial step in resealing your windows and must be carried out in accordance with the instructions of the manufacturer to ensure it bonds with the window properly and creates a watertight seal to keep out moisture and air.

Use a smoothing tool to apply the sealant. This will ensure that the window is completed professionally and has no gaps. Once the silicone is cured you will be able to enjoy your newly re-sealed double-glazed windows and all the benefits that come with them.
