20 Replacement Sealed Double Glazing Units Websites Taking The Internet By Storm
Replacing Double Glazed Units

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

The new model, designed to exact measurements, is waiting for its moment and demands attention and precision. This is the moment that halts time and puts everything in perspective.

Remove the Old Unit

Removing the old unit is a critical step to ensure that the new double-glazed window is built to precise measurements. Clean the frame with care to get rid of dust, dirt or old sealant. Repair any damage that's present. Wood filler and sanding may be used to repair minor damage however, major damage might require professional repair.

When the glass is removed, it is important to measure its height, width, and thickness. The best method for doing this is to remove the glazing beads that secure the unit. This is a delicate task that requires patience and prudence. Take your time and wear safety equipment to avoid slips and shards.

The best way to begin is to remove the bottom bead of the glazing strip using a sharp chisel or sharp wide-bladed screwdriver. After the bead is removed, it is recommended to ask for help from someone to hold the sealed unit as you take out the remaining beads. This is because the unit can easily fall out of the frame and smash.

After all the beads have been removed, it's essential to carefully measure the dimensions of the width, height and thickness of the unit that is currently in use. The measurements can be used to precisely design an appropriate replacement unit for your home. It can also be used as a guideline to ensure that the new unit is sized to fit the frame. It is crucial to ensure that the window is properly fitted, as a mismatch will not only require the whole unit to be disassembled and reassembled, but it will also affect the performance of the unit. This is particularly important in Australia where homes are often exposed to extreme weather conditions.

If you're replacing a fixed window or a sliding door that has an opening or fixed sash, ensure that your new window is of the right size. UPVC frames offer very little space for movement, and a sealed double glazing unit that is even a few millimeters too big will not be able to fit. To ensure accurate measurements make sure you measure with care and consult a professional.

Remove the glass from the frame after you are sure that the replacement is the right size and has been properly fitted. Be sure to work in a well-lit area, and wear safety equipment, such as gloves, to avoid injuries from glass shards. Make use of a putty blade to cut off the glaze stripes or beads that hold the glass into the frame, and remove them from the perimeter of the pane. The glass is fragile, and you should be cautious to avoid sliding or straining the frame.

Make sure the frame can be opened and closed smoothly after the new double-glazing unit sealed is installed. It should be a snug fit, but you are able to alter this if needed by adding or removing packers. For instance, if the frame is a sliding door, you might need to add extra packers on the hinge and at the opposite corners to stop the sash from getting caught or rattle when it opens.

Then clean the frame. Take off any old sealant or glazing tape If needed. Assess any damage and make small repairs with wood filler or sanding if necessary. The frame will be rehabilitated by a final cleaning and inspection and will be able to stand up to the harsh Australian weather for a long time.

Lifting the New Unit

Over time, double glazed sealed units (or a sealed unit as it is more commonly known) may develop issues such as moisture in-between panes and/or misting. This can compromise the effectiveness of your windows and allow cold air to enter and warm air from your heater to escape, resulting in uncomfortable energy bills and discomfort.

This type of seal failure generally occurs due to age, general wear and tear, or harsh chemical cleaners that degrade the sealing material. Sometimes however, the cause can be attributed to the expanding and shrinking of the glass due to temperature fluctuations and seasonal changes.

Once the frame is cleaned and ready and clean, you can move the unit up into its place. This is a thrilling step because you've created a positive impact on your home, increasing its warmth during winter and cooling in summer, whilst also helping to reduce your energy bill.

It is crucial to ensure that the new unit fits correctly into the frame prior to securing it to the frame. This is essential to ensure that the frame isn't damaged and the glass.

If your windows use glazing tape or sealant it's time to put a bead around the perimeter of the glass and frame, creating a strong protection against air and moisture infiltration. Make sure to tighten the sealant carefully, ensuring it's secure but not tight enough to cause stress on the glass or frame. Finally, give yourself a pat on the back for a job well done, and then enjoy your newly-installed double-glazed window!

Securing the Unit

With the new unit set snugly in the frame and a fresh bead of sealant covering its perimeter This is the moment to mark the end of your project. The unit is now secured to withstand Australia's varied weather which guarantees warmth in winter and coolness in summer. This is the precise measurements and removal are validated as a proof that the product was designed according to the exact dimensions.

It is essential to find the right balance between the need to secure the unit and not straining the glass. If it is too loose, the window could lose its airtight seal. If it's too tight, it might cause damage to the frame or weaken the material. Each screw should be put in its original place, and rotated just enough to hold the unit securely without putting pressure too high.

This is the final step in a transformative project that enhances the comfort of a home and energy efficiency as well as its appearance. With the new double glazed unit snugly seated within the frame, and securing a fresh bead of sealant around its perimeter, this is the moment that signifies the completion of your project.

The insulating cavity between the panes of glass is filled either argon gas, or a desiccant. Argon is, unlike air is a bit less thermal conductivity, which decreases heat transfer. In addition, a desiccant adsorbs moisture from the air, stopping mould and condensation from building up within the frame. The spacer bar is constructed of aluminium and is an essential component of the insulation system. The aluminium not only prevents heat transfer but also keeps the edges warm of the window that is insulated to avoid condensation.

Checking Your Work

It is crucial to allow the silicone sealant to cure after you have put in the new unit. It will take at least 4 hours for it to reach its maximum strength and create an impervious barrier. While you wait, visually examine your work to determine whether there are any gaps or other issues that could affect the effectiveness or appearance.

It is also a good moment to inspect the seals and frame for signs of damage that require attention, and to determine whether replacement of the entire window is needed. A faulty seal can cause a significant impact on the energy efficiency of your home, causing drafts and cold spots. It can also allow ultraviolet rays into the home, causing fade of furniture and reducing the lifespan of carpets and curtains.


If you're experiencing any of these issues it's a sign that your double glazing is in need of replacement. Making it a priority to replace it immediately will reduce your energy bills and provide a more comfortable and relaxing home.

It is a complicated and labor-intensive job that requires the correct equipment, precise measuring and careful preparation. It is not an DIY job, and should only be completed by a professional in uPVC windows and doors, who can ensure the correct fitting of the replacement unit, to ensure your home is protected from the elements. Their expertise will ensure that the double-glazed unit you select is quiet and efficient, providing warmth in winter and cooling in summer. This will shield your home from weather damage.
