Benefits of Replacement Double Glazed Units
Double glazed windows (or sealed units) can become misted or blown if the seals wear out and cause heat loss and costly heating bills. Replacing the unit will restore an air-tight seal that prevents condensation, draughts, and water leaks.
The first step is to use a high-quality sealant that can endure thermal expansion and contraction.
1. Preparation
Double glazing, also known as sealed units as they are often referred to, enhance the efficiency of your home and increase its security by providing a solid protection against intruders. They also serve as a fantastic protection against condensation and cold air drafts that could otherwise get into your living space.
Over time, however double glazing will fail and the insulating gas that keeps your home at a comfortable temperature may escape. If this happens, your warm home won't be as energy efficient and it'll cost you more to heat during winter and cool in summer.
To prevent this from happening, a replacement frame will have to be installed. It's a simple task that most DIYers can do However, it's crucial that you set up your frame correctly to avoid costly mistakes.
First, take the glazing beads or sealing strips from the frame. It's a delicate task that requires a lot of patience and steady hands.

There are several ways to accomplish this, based on the design of your window. If your window's design incorporates glazing tape wrapped around the frame's edge to create an insulated surface for the glass. For windows with warm edge systems, you are also required to use an enclosed spacer tube filled with desiccant. This adsorbs any moisture that may have been trapped in the manufacturing process and then eventually made its way to the window.
2. Removal
Double glazed units, or sealed units, as they're called, may break down over time. In this case, the inert gas that is occupying the space between the glass panes leaks out. This can alter the temperature control of your home as well as the efficiency of energy use.
It is crucial to change the seal in the event of this happening. This process is not only an essential requirement but can also enhance the security of your home. The use of toughened safety glass and laminated glazing makes it much harder for criminals to break into your home.
It is important to carefully take care to remove the old sealed unit. This step is a bit difficult because the glass could be quite heavy. It is best to have an extra pair ready for assistance. Lift the glass slowly and steadily to avoid strain or breakage.
It's a good idea to clean the window frame thoroughly with an old paintbrush (4 inches is ideal). This will remove any dust or debris that might have built up within the frames over time. Inspect the frame for any damage. Small damage can be repaired with wood filler and sanding. More serious damage might require professional repair.
Before you put the new glass in its spot, it is important to measure it accurately. This can be done by a professional but if you're comfortable enough to do it yourself this can be achieved using the straight edge of an appropriate ruler. Once you've got the measurements, you can begin to re-fit the glazing beads.

When you're done installing the glazing beads it is essential to make sure that the glass is completely flush with the frame. This is to avoid any moisture that could lead to condensation between the panes.
3. Installation
Modern replacement double glazed units, also referred to as sealed unit windows, offer numerous benefits for the home owner, including an increase in energy efficiency. They function by encapsulating an air layer between two panes of glass, and the spacer bar has desiccants to absorb moisture and prevent condensation from forming between the glass panes. These features allow the house to stay warm in winter and cool in summer, reducing heating and cooling costs, and creating a pleasant living space.
Once the new double glazed unit is installed, it can be fixed to the frame with glazing beads or sealant. This is an essential step to ensure that the window is sealed and is ready to withstand the diverse weather conditions in Australia from Tasmania's fierce winds to Queensland's scorching sun.
Be careful not to damage the new unit, it's essential to place the sealant and beads with precision. It's also essential to choose a sealant of high-quality that is able to stand up to thermal expansion and contraction without becoming brittle or breaking. It is essential to examine the unit following installation to look for signs that it is malfunctioning.
The most frequent indications that a sealed unit has 'blown' are condensation between the panes of glass or the glass appearing cloudy. It is recommended to replace your double-glazed unit in the event that you notice any of the signs.

4. Checking
Double glazing is a good barrier between the elements and your home and allows you to control the climate in your home. This is especially crucial in winter, when blown up or misted-up sealed units may let heat leak out and increase energy costs. Sealing them up with a new seal can help keep the heat in, and your energy costs down.
The final step of this process is to examine the newly sealed unit for any signs of wear or damage. It is also important to ensure that the window is securely installed in the frame and is aligned evenly with the surrounding structure. It's important to take your time when examining the frame and glass for any problems because mistakes can be costly.
If the seal has broken or the desiccant is low it is advisable to replace the entire unit rather than just replacing the damaged panes. Failed or leaking double glazed windows allow heat to escape into the environment and cause your heating system to be more efficient in maintaining the same temperature. A leaky sealed unit may also let moisture in the air-filled void between the glass panes, which results in condensation.
This is a difficult procedure, since the unit has been heated and needs to be removed with care to avoid any damage. When you are removing the unit, it's essential to place yourself in a firmly and have a spare pair of hands ready to assist you during the removal process.
