Replacing Double Glazed Units

Double-glazed units can be replaced to lessen noise and heat loss, and also reduce heating costs. Modern coatings and argon/krypton gas-filled units make them extremely energy efficient.

The new unit, built to exact measurements, is awaiting its time. It needs care and precision. This is a moment that is a moment that stops the world and puts your effort into perspective.

Remove the Old Unit

It is crucial to remove the old unit to ensure that your new double-glazed window is made to exact measurements. Clean the frame carefully to remove any dust, dirt or old sealant. Repair any damage that's present. Wood filler and sanding may be used to repair minor damage, but major damage may need professional repair.

Once the glass is removed, it's crucial to determine its width, height and thickness. This can be accomplished by removing the glass beads that hold the unit. This delicate procedure requires patience and prudence. It is recommended that you take your time and use safety gear to protect yourself from unexpected shards of glass and accidental slips.

Begin by removing the lower part of the glazing strip using a chisel that is sharp, or a wide-bladed, sharp screwdriver. Once the bead has been removed, it is advisable to get help from someone to hold the sealed unit as you take out the remaining beads. The unit could be thrown off the frame and break.

After removing all the beads, it is important to determine the width, height and the thickness of the present unit. The measurements can be used to precisely design an appropriate replacement unit for your home. Additionally it will provide a reference for ensuring that the new unit will fit into the frame. It is essential to ensure that the window fits correctly, as a mismatch will not only require the whole unit to be disassembled and reassembled, but it will also reduce its performance. This is particularly important in Australia where homes are often exposed to extreme weather conditions.

Preparing the Frame

If you are replacing a fixed window or a sliding door with an opening or fixed sash, make sure the new window is the right size. UPVC frames have very little movement and a double-glazed sealed unit that is a couple of millimeters too big will not work. Be sure to measure carefully, and consult a professional or manufacturer's guide in order to make sure you get accurate measurements.

Once you have a clear understanding of the dimensions of the replacement and are confident that it is correctly fitted take the glass out of its frame. Make sure you work in a well-lit area, and wear safety equipment, such as gloves, to avoid injury from shards of glass. Use a putty blade to cut off the glazing strips or beads that secure the glass to the frame from the perimeter of the pane. The glass is fragile and you must be cautious to avoid sliding or pulling the frame.

When the frame is ready to receive the brand new sealed double glazing unit, ensure that it will be capable of opening and closing smoothly. You can alter the fit by removing or adding packing. If the frame is intended for sliding glass doors you may need to add additional packers to the top of the hinge and the opposite corner to prevent the sash from being caught when it opens.

Then, clean the frame. Remove any old sealant or glazing tape If necessary. Check for any damage and make small repairs by using wood filler or sanding, if required. The frame will be refreshed with a final cleaning and inspection, allowing it to stand up to the harsh Australian weather for a long time.

Lifting the New Unit

Over time, double-glazed units can experience problems like condensation between the panes or misting. This can affect the performance of your windows, allowing cold air to enter and warm air from your heater to escape, resulting in high energy bills and discomfort.

This type of failure in seals is usually the result of aging or general wear and tear or harsh chemical cleaners that damage the sealing material. Sometimes however, the reason can be traced to the shrinking and expanding of the glass as a result of temperature changes and seasonal changes.

After the frame is clean and ready and clean, you can lift the new unit onto the frame. This is an exciting step as you have just improved the heating of your home in the winter months and cooling in the summer while also decreasing your energy bills.

Before securing the unit, it's important to ensure that the new unit is properly fitted into the frame. A little attention during this stage can prevent damage to the frame as well as the glass.

If you use glazing tape or sealing tape on your windows, this is the perfect moment to apply a bead along the perimeter of the glass. This will create a strong barrier that blocks air and moisture from getting into the window. Make sure to tighten the sealant with care but not so much that it causes stress to the glass or frame.

Securing the Unit

This is the time when the work is done. The unit will be securely seated in the frame, and a fresh sealant will be applied to its perimeter. The unit is now secured to withstand Australia's diverse weather conditions, which is a guarantee for warm temperatures in winter and cool temperatures in summer. It's the moment when you can confirm the accuracy of your measurement and removal, a proof of a unit that was designed according to precise measurements.

It is crucial to find the perfect balance between securing the unit and not straining the glass. If it's too loose, then the window may be unable to seal its airtight. If it's not tight enough, it may damage the frame or warp material. Each screw must be put in its original position, and turned just enough to hold the unit securely without putting pressure too high.

This is the last step in a transformational plan that enhances the comfort of a home and energy efficiency as well as its appearance. The moment you are complete, with the new double-glazed unit safely set in the frame and a new bead adorning the perimeter.

The glass panes is filled either with either argon or a desiccant. Argon is, unlike air is a bit less thermal conductivity, which can reduce heat transfer. Desiccants also help to absorb moisture from the air, which prevents mould and condensation in the frame. The spacer bar is constructed of aluminium and is an essential part of the insulation system. Aluminium not only impedes heat transfer, but also helps keep the edges warm of the window insulated to avoid condensation.

Verifying Your Work

When you've put up the new unit and applied a bead of silicone sealant around the edge it is essential to allow it to set - don't handle it! It takes at least 4 hours for it to attain its full strength and create an impervious barrier. While you are waiting, take the time to examine your work visually and see if you can spot any gaps or other issues that could affect the performance or appearance of the product.

This is also a good moment to inspect the seals and frames for indications of damage that require attention, and to determine whether replacement of the entire window is necessary. A damaged seal can have a significant impact on the efficiency of your home's energy usage, causing drafts or cold spots. It also lets ultraviolet rays into the house and cause furniture to fade and carpets and curtains to wear out faster.

If you're experiencing any of these issues it's a sign that your double-glazed windows need replacing. Taking care of it quickly will reduce your energy bills and create a more comfortable, relaxed home environment.


It is a complex and labor-intensive process that requires the right equipment, precise measuring and careful preparation. It is not an DIY project and should be undertaken by a specialist who has expertise with uPVC Windows and Doors. They can ensure that the new unit is installed correctly to protect your home from the elements. Their experience will ensure the double-glazed unit you choose is both quiet and efficient, providing warmth during winter and coolness in summer. This will protect your home from weather damage.
