Replacing Double Glazed Units

Replacing double-glazed units is a home improvement project that can greatly reduce heat loss, increase insulation from noise and reduce heating costs. Modern coatings and argon/krypton filled units make them extremely energy efficient.

Remove the Old Unit

The removal of the old unit is a critical step that will help ensure your new double glazed window is built according to the exact measurements. Clean the frame carefully to remove any dust, dirt, or old sealant. Repair any damage that is present. Repairs of minor amounts can be made by using wood filler or sanding but major damage might require professional repairs.

After the glass is removed, it is essential to measure its width, height and thickness. The best way to do this is to take out the glass beads that bind the unit. This delicate process requires patience and caution. Take your time and wear safety gear to avoid shards and slips.

Start by taking off the bottom of the glazing strip with a chisel that is sharp, or a wide-bladed screwdriver. Once the bead has been removed, it is recommended to seek assistance from a person who can hold the sealed unit while you remove the remaining beads. The unit is prone to fall off the frame and break.

UPVC frames have little room for movement, and a sealed double glazed windows seal replacement glazing unit that is even just a few millimeters larger will simply not fit. To ensure accurate measurements make sure you measure with care and seek the advice of an expert.

When you have a clear idea of the dimensions of your replacement and are sure that it is correctly fitted, remove the glass from its frame. Wear safety gear, such as gloves and work in a location that is well-lit to avoid injury from glass fragments. Utilize a putty knife to remove the glazing beads or strips that hold the glass to the frame, from around the perimeter of the pane. The glass is brittle, and you should be careful to avoid slipping or pulling the frame.

Verify that the frame will open and close smoothly when the new sealed double-glazing unit is installed. You can adjust the fit as needed by adding or removing packing. If the frame is intended for a sliding glass door you may need to add packers to the top of the hinge and the opposite corner to avoid the sash from catching when it opens.

Finally, clean the frame and get rid of any old sealant or glazing tape in the event of need. Check for any damage, and make small repairs if required using wood filler or sanding. The frame will be rejuvenated by a final cleaning and inspection so that it can endure the harsh Australian weather for many years.

Lifting the New Unit

Over time double glazed sealed units (or a sealed unit as it is often called) can develop issues such as moisture in-between panes and/or misting. When this happens the effectiveness of your window is diminished by letting cold air in and allowing warm air from your heating system to escape which can result in higher energy bills and a decrease in comfort.

This kind of failure in seals generally occurs due to age or general wear and tear, or harsh chemical cleaners that deteriorate the sealing material. Sometimes, however, the cause could be due to the expanding and shrinking of the glass due to temperature fluctuations and seasonal changes.

Once the frame is clean and ready, you can begin to move the new unit into place. This is a thrilling moment as you've improved your home's heating in winter and cooling during the summer, while decreasing your energy bills.

Before securing the unit, it is crucial to make sure that the new unit fits into the frame. A little bit of care in this phase will help prevent any damage to the frame, as well as the glass.

The insulating cavity between the panes of glass is filled either argon gas, or a desiccant. As opposed to air, argon is much lower thermal conductivity and reduces heat transfer through the glass. Desiccants also adsorb moisture from the air, which prevents condensation and mould from the frame. The spacer bar, typically made of aluminium is also an essential part of the insulating system. Aluminium not only impedes heat transfer but also keeps the edge of the insulated window to prevent condensation.

Verifying Your Work

It is important that you allow the silicone sealant to set after you have put in the new unit. It takes at least four hours for the silicone sealant to attain its maximum strength and form an impenetrable barrier. While you wait, visually examine your work to determine whether there are any gaps or issues which could affect the efficiency or appearance.

It's also a good time to inspect the frame and seals to determine if there are any signs of damage, and determine if the whole window needs to be replaced. A faulty seal can have a huge impact on the energy efficiency of your home, leading to drafts and cold spots. It can also let ultraviolet rays into the house which can cause furniture to fade and carpets and curtains to wear more quickly.

If you're having any of these issues the double glazing might need to be replaced. It will help you save money on your energy bills and create a more relaxed and comfortable living space.
