Why Replace a Double Glazed Sealed Unit?

If you replace a double-glazed sealed unit you're doing more than fixing the broken window. You increase the health and energy efficiency in your home.

Make sure your work is completed correctly and you'll be able to enjoy years of comfort and savings. It is crucial to make the effort to prepare and inspect the frame.

Preparation

Double-glazed units, also called sealed units, are a vital element of any Australian home. They improve the quality of life, energy efficiency and security by creating an insulation wall between the inside and the outside world. However, with time they can begin to fail. It is essential to identify the reason for this and the best way to repair it.

Over time the inert gas that fills the space between the glass panes could escape through cracks or other damage to the unit. This is a double-glazed unit. In this case, it's best to replace the unit to restore the thermal performance and airtight seal to prevent cold winds from entering the home.

When replacing the frame, it is crucial to assess the condition of the frame and make sure it is in good working order. If there is evidence of damage, it needs to be repaired immediately to avoid further damage or water leaks. It is also essential to ensure that the sealed unit is the correct size for the existing frame. The UPVC frames have very little tolerance, and if the replacement is even just a few millimetres larger than the original, it will not fit in place and may be difficult to install properly.

It is a good idea to enlist someone you know to assist with the removal of the old unit and assist in the installation of the new unit. This will ensure that the glass is set properly and the task is completed swiftly and neatly.

It is essential to clean all surfaces of the frame after taking away the old unit. This will get rid of any dirt or residue and prepare the frame for a new sealant.

Once the frame and glass have been cleaned it is necessary to measure the thickness of the existing sealant by using a set calipers (or similar tool). This will be useful to know before purchasing a replacement sealant since it will need to be the same thickness to ensure a snug fit in the existing frame.

Removal

Over time, double glazed windows or sealed units as they are known, may fail. replacing sealed units can become smoky, foggy, steamed up or cloudy when the air tight seal that separates the two panes of glass fails. This allows moisture into the home, which can cause calcium deposits to cause stains on your glass. It also reduces energy efficiency and allows cold air to get in.

One option to solve this is to replace the double glazed unit within the unit itself. This is costly and can cause disruption. It is much easier and less expensive to replace the seals on the edges of the double-glazed unit. This will increase the efficiency of your heating system, reduce energy bills and improve the acoustics your home.

You will need to remove the old unit from the uPVC frames. This can be a messy and dangerous job, but with careful consideration and the correct tools you can safely remove the existing glass and have an empty frame ready for the new sealant.

After taking down the old unit, it is a great idea to thoroughly clean the uPVC frames. This will provide an uncluttered surface for the new sealant to adhere to. It will also identify any areas of wear or damage that may require attention. Before beginning the replacement process, it is crucial to repair any damage or wear. This can affect the performance of the window.

To clean the frame, use a paint brush to remove any debris or dirt the edges of the frame. Examine the frame for signs of rot and damage that requires attention. This is an essential step to maintain the integrity of your house and ensure that the replacement double glazing is functioning as it should.

Installation

Over time, double glazing units may fail or as they are referred to "sealed units". This is most commonly because of a flaw in the air tight seal around the edge of the two panes of glass. This allows the gas inert argon to escape from the window which is designed to be an insulator. This is not a good thing as it lowers the thermal efficiency of the windows, increasing heating bills significantly. Double glazing will improve the insulation in your home, and will reduce the cost of energy.

Examining the extent of damage is the first step to replace an item that is sealed. A thorough inspection will reveal issues such as cracks, chips, or fogging between glass panes, as well as damage on the frame and seals. This will help determine if replacement is needed or if other repair options are feasible.

After the assessment after the assessment, the removal process is able to begin. It is important to ensure that the new window is installed properly and a high quality of craftsmanship is maintained at all times. This is especially important during the sealing phase. The appropriate kind of silicone sealant has to be chosen that is able to withstand Australia's diverse weather conditions and not become soft or break easily.

It is important to clean the frame and eliminate all debris and dust prior to installing the new sealed double-glazed unit. Clean any old sealant using the help of a utility knife or a putty knife. The frame should be ready for the new sealed units. Before applying the new silicone sealant it is a good idea to apply caulking remover.

It is crucial to be precise in measuring the width and height of the existing unit. This is because even a tiny error can cause a problem with the design of a new unit and cause additional expenses. To avoid this, take measurements from several points to account for tiny variations in the frame.

After the installation, you'll need to seal your frame using silicone caulk. This isn't merely an officiality, it's a crucial step in safeguarding the window's new double glazing against Australia's many weather conditions.

Sealing

Double glazing is designed to keep your home cooler during summer and warmer in winter months by providing an additional layer of insulation containing the inert Argon gas. Over time however the sealed units (also called glazed units) could fail, causing the insulating gas to leak out. The signs of this may vary but often include a foggy appearance to the glass or a draft in your home.

To fix this you'll have to replace the sealed unit. There are many different ways that you can accomplish this, but the most important factor is to ensure you have the correct measure your new window to avoid the risk of the glass you have just replaced breaking.





The first thing to be done is to prise the beads from the frame with the help of a sharp chisel or screwdriver. Then, carefully remove the sealed unit. Once you have removed the seal the next step is to accurately measure the width, height and thickness of the existing unit. This will ensure that the replacement is built to the correct dimensions, and can provide superior and efficient level of insulation.

After the new sealed unit has been correctly measured, the next step is to apply the new sealant made of silicone. This is a vital step in resealing your windows and should be done according to the manufacturer's instructions to ensure that it adheres to the window in a proper manner and creates a watertight seal that will keep out moisture and air.

Make use of a smoothing tool when applying the sealant. This will ensure that the window is sealed professionally and has no gaps. Once the silicone is set and dried, you can enjoy your newly resealed double-glazed windows and all the benefits they bring. They can make your home more comfortable as well as reduce your energy costs.
