Take the old unit out of the way

Double-glazed windows or sealed units as they are also called, may break down over time. Fogging between the two glass panes is a common symptom. This happens when condensation forms inside the cavity of the unit. This is a good indication it is time to replace the unit.

Replacement units are an effective way to reduce heating costs and increase the efficiency of your home's energy use. The insulating space between two panes of glass reduces the transfer of heat, which can reduce the power bill, and also keeps your house warmer in winter and cooler in summer. It can also help to reduce noise from outside, creating a more comfortable, relaxing living space.

The first step in replacing windows with double glazing is to remove the old sealed unit. It might be difficult, but with the right tools it isn't. It is important to have another pair of hands at this point since the machine is hefty and could be dangerous if handled incorrectly. It is best to follow a systematic approach and remove the retaining beads around the frame.

With the old unit removed and the frame ready for the new unit to be fitted it is now necessary to precisely measure the size, height and width of the unit that will be replaced. This is important since the UPVC frames that the sealed unit is within have very narrow tolerances. If the unit is too large it will not fit.

Next, take off the glazing tape from the frame's edges as well as the putty to prepare it for installation of the new unit. It is important to use a premium silicone sealant for this since it will result in an water-tight and durable seal around the edges of the frame that will last for a long time to come.

Installing the New Unit

Double-glazed windows are composed of two glass panes, separated by a spacer bar that creates an insulating gap filled with air or gas. The spacer bar could be made of Low-E (Low-Eissance) glass or desiccants to reduce moisture infiltration. The window designer will take exact steps to ensure that the new sealed unit fits perfectly within the frame. window gaskets replacement Repair My Windows And Doors will help to ensure that the replacement is energy efficient and provides homeowners with the best possible results.

Once the old unit is removed then the next step is to prepare the frame for the installation of the new sealed unit.

To do this, pull out the "beads" by using a sharp chisel or a wide-blade screwdriver, and work slowly to avoid damaging the frame or surrounding structure.

Apply a thin layer of washing-up liquid over the rubber seal of the bead prior to installing the sealed unit. This will help the unit slide into position and avoid damage to the frame or unit. If your window design uses brickmould made of plastic, it should be installed prior to fitting the bead to help prevent it from rotting as well as moisture infiltration.

Verifying Your Work

Modern double-glazed units (also known as IGUs) are composed of two or more glass panes separated by a spacer which creates a gas or air gap for insulation. Spacer bars are often coated with a solar-control coating that regulates the flow of light into the home and helps with insulation. They are designed to make your home more comfortable in the winter and cooler in the summer. This will reduce the amount of energy your heaters and fans have to use, which is healthier for the environment.

It is time to replace your sealed unit in the event that it has failed. Failed units allow air to be introduced into your home, which can reduce the efficiency of cooling and heating. This can also cause moisture to leak between the window panes, leading to a build-up of condensation and mould.

The presence of condensation between windows is a sign your window requires to be replaced. It's no longer serving its purpose of keeping out cold air and allowing warm energy from the heating system in. In addition, the misting will eventually make the window unsightly.

After cleaning the frame, a quick inspection will reveal any damage that needs to be repaired. This is particularly important for timber frames which are susceptible to deterioration due to Australia's harsh weather. Sanding and wood filler can be used to repair minor damage however professional repair is required for the most serious damage.


Once you've completed the repair, select a sealant of high quality that is able to stand up to thermal expansion without becoming fragile. Make sure that the sealant is evenly spread across the entire perimeter of the frame and then smoothed to get a professional, clean finish.

The final step is to secure the unit within the frame. Insert the retaining beads, and fix them with the wedge gasket. This last step is more than a formality.

IG (insulated glass) sealed units, commonly called double glazed windows, are made up of two sheets of clear or Low-E glass, separated by gas-filled spacer bar, which may also include desiccants. Some insulating units are also filled with gas, allowing them to achieve higher Window Energy ratings.

Over time, double-glazed units or sealed units, as they are more commonly called, can fail. This may be due to the way they were originally constructed, or the use of cleaning products with abrasives which damage the seals. In certain instances the thermal insulation properties could be damaged. This could lead to an increase in effectiveness.

The airtight seal that is formed between the glasses is the most frequent failure. This can be caused by gradual degradation over time. Temperature fluctuations cause the glass to expand and contract, causing the seals to weaken and looser. This can result in a leak between panes in some cases.

To prevent this from happening, it is recommended to replace the sealing beads with premium silicone or another similar product. It's easy to do this by removing the beads with a chisel.

It is also essential to ensure that the glazed unit is placed exactly within the frame. You can do this by measuring at different locations across the frame.
