Double Glazed Sealed Unit Replacement: 11 Things You're Forgetting To Do
Why Replace a Double Glazed Sealed Unit?
You're doing more than just fixing a broken glass window when you replace a sealed double-glazed unit. You're improving the health and energy efficiency of your home.
Make sure that the work is done correctly and you'll have many years of savings and comfort. Making the effort to examine and prepare the frame is crucial.
Preparation
Double glazed units, also called sealed units, are an essential element of any Australian home. They can improve comfort and energy efficiency, as well as provide security and lower noise levels by forming an insulating barrier between the inside and the outside world. However, with time they can start to fail. It is crucial to understand the reason for this and the best way to repair it.
Over time the inert gases that fill the space between glass panes can escape from the unit via 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 winds from entering your home.
It is important to assess the frame's condition prior replacing it. It is crucial to fix any damage immediately in order to avoid further deterioration and water leaks. It is essential to make sure that the new sealed unit is compatible with the frame you have. The UPVC frames have a very limited tolerance and if the replacement is even a few millimetres too big it will not fit in place and will be difficult to install properly.
It is a great idea to ask a friend or colleague for help in removing the old unit and then assist with the installation of the new unit. This will ensure that the glass is positioned correctly and the task is completed quickly and neatly.
After the old unit has been removed, it is crucial to wash the entire surface of the frame. This will get rid of any remnants of residue or dirt, prepare the frame for new sealant and ensure it is ready for a new installation of the new unit.
After cleaning the frame and glass, it's important to measure the thickness (or other tool) of the sealant. This is important to know prior to purchasing a replacement sealant because it must be the same thickness to ensure a secure fit into the frame.
Removal
Double glazed windows or sealed units or sealed units, as they are commonly called, may break down over time. They may become misty or foggy, steamed up or cloudy when the air-tight seal that separates the two panes of glass fails. This allows moisture to get in and result in calcium deposits that could scratch the glass's surface, as well as reducing energy efficiency and allowing cold air to enter your home.
One solution is to replace the double-glazed unit within the unit itself. However, this could be expensive and can be disruptive. It is simpler and less costly to replace the seals on the edges of the double-glazed unit. This will restore thermal efficiency as well as reduce the cost of energy and improve the acoustics in your home.
You'll need to take the old unit from the uPVC frames. It's an unpleasant, hazardous job. But with the right tools and care you can safely take off existing glass.
After getting rid of the old unit it is a good idea to thoroughly clean the uPVC frames. This will provide a clean surface for new sealant to adhere to. It will also reveal any areas of damage or wear that might require attention. It is essential to address these before continuing with the replacement process as this will impact the performance of the new window.
To clean the frame use a paintbrush to remove any dirt or debris around the edges of the frame. Check the frame for signs of rot and damage that requires attention. This is an essential step to maintain the integrity of your home and ensure that your new double glazing performs as it should.
Installation
Over time, double glazing units can break or as they are also known 'sealed units'. 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 that is intended to be an insulator. This is not a good thing as it reduces the thermal performance of the windows, increasing heating bills significantly. A double glazing replacement system will help to improve the insulation of your home and reduce your energy costs.
The assessment of the extent of damage is the first step to replace the sealed unit. A careful inspection can reveal problems such as chips, cracks or fogging between the panes glass, as in addition to damage to the surrounding frame and seals. This will allow you to determine if replacement is needed or if other repair options are feasible.
Once the assessment is complete the removal process can commence. It is important to ensure the new window is correctly installed and a high quality of workmanship is maintained throughout the process. This is especially important during the sealing stage. The correct type of silicone sealant must be used that can withstand Australia's diverse weather conditions and not turn brittle or break easily.
Before installing the double-glazed sealed unit, it is crucial to ensure that the frame is free of dust and debris. Remove any old sealant using an utility knife or putty knife. The frame should be ready for the new sealed units. Before applying the new silicone sealant, it is recommended to use caulking remover.
It is also crucial to precisely measure the dimensions of the glass unit that is in use. This is because even a tiny error can cause a problem with the design of a new unit and cause additional expenses. To make sure you don't get this happen, take measurements from several points to account for any minor variations in the frame.
After the installation, you'll need to seal your frame using silicone caulk. This step is not only a formality, but it's crucial to shield the new double-glazed window from Australia's various weather conditions.
Sealing
Double glazing is designed to keep your home cooler during summer and warmer in the winter by providing an extra layer of insulation that contains the inert Argon gas. Over time however the sealed units (also called glazed units) may fail, causing the insulating gas to leak out. The signs of this may vary but usually include a hazy appearance to the glass or a draught inside your home.

This will ensure that your replacement is constructed to the correct dimensions and can provide high-quality and effective level insulation.
The next step is to apply a new silicone sealant after the replacement sealed unit is properly sized. replacement sealed units repairmywindowsanddoors is a crucial step in resealing a window. It should be done in accordance with the instructions of the manufacturer to ensure it is able to bond properly with the window and forms an airtight seal.
