Why Replace a Double Glazed Sealed Unit? You're doing much more than fixing a damaged glass window when you replace a sealed double-glazed unit. You're enhancing the health and energy efficiency of your home. If you perform your job correctly If you do it correctly, you will have savings and comfort for a long time. It is important to take the time to prepare and inspect the frame. Preparation Double glazed units, also known as sealed units, are a crucial element of any Australian home.

If this happens, it is important to understand the cause of this and the steps to take to correct it. In time the inert gases that fill the space between glass panes can escape through cracks or damage. This is a blown double-glazed unit. In this case it is best to replace the unit to repair the thermal performance and airtight seal to prevent cold air from entering the home. It is essential to check the frame's condition prior replacing it. If there is evidence of damage it should be repaired immediately to avoid further deterioration or potential water leaks. It is important to make sure that the new sealed unit is compatible with 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 may be difficult to install correctly. It is an excellent idea to ask someone you know to assist with the removal of the old unit as well as assist with the installation of the new one. This will ensure that the glass is set properly and the task is done quickly and efficiently. It is crucial to wash the frame's surfaces after removal of the old unit. This will remove any dirt or residue and prepare the frame for the application of a new sealant. Once the frame and glass have been cleaned it is important to measure the thickness of the existing sealant with a set of calipers (or similar tool). This information can be useful when deciding on a new sealant unit, since it will need to have the same thickness in order to fit snugly into the existing frame. Removal Over time, double glazed windows, or sealed units as they are called, can fail. When the airtight seal that creates a barrier between two panes is damaged, the windows can become foggy, misted, steamed or cloudy. This allows moisture to enter and result in calcium deposits that could cause stains on the surface of the glass as well as reduce energy efficiency and allowing cold air to enter your home. One way to resolve this is to replace the double glazed unit in itself. However, this could be expensive and inconvenient. A much cheaper and easier option is to replace the gasket seals around the edges of the double-glazed unit.

It is crucial to address these issues prior to proceeding with the replacement process since it will affect the performance of the new window. Use a paintbrush to remove debris and dirt from the frame's edge. You should also check the frame for signs of rot or damage that require attention.

Installation Over time, double glazing units or sealed units as they are commonly called can fail. The most common reason for this is because of a flaw in the airtight seal around edges of the two panes. This allows the gas inert argon to escape from the window, which is designed to be insulating. This is not a good thing since it decreases the thermal performance of the windows, thereby increasing heating costs substantially. A double glazing replacement system will help to improve the insulation of your home and lower your energy costs.

Care must be taken to ensure the new window is properly installed and that a high standard of craftsmanship is maintained throughout the process. This is particularly important when sealing the window. It is important to use an adhesive made of silicone that can withstand Australia's diverse weather conditions and will not break or become brittle. Before installing the new double-glazed sealed unit it is essential to make sure the frame is free of dirt and dust. A utility knife and a putty knife should be used to eliminate any sealant that is old and ensure that the frame is prepared for the new sealed unit. Before applying the new silicone sealant, it is a good idea to employing a caulking remover. It is essential to precisely measure the height and width of the existing unit. A small error can ruin the fit and cause extra costs. To avoid this, take measurements from several points to allow for slight variations in the frame. Once the installation is complete after which it is time to seal the frame with an adhesive caulk made of silicone. This isn't just a formality; it's an essential step to protect the windows that are double-glazed against Australia's many weather conditions.
