Replacing Double Glazed Units

Double-glazed units can be replaced to lessen noise and heat loss, and also reduce heating costs. With modern coatings and argon or Krypton gas fills, they are very energy efficient.

The new unit, built to exact measurements, is waiting for its time. It is a task that requires attention and precision. This is the moment that halts the clock and puts everything into perspective.

Then, remove the old unit

It is important to remove the old unit in order to ensure that the new double-glazed window has been made to the exact measurements. Clean the frame carefully to remove dust, dirt, or old sealant. Repair any damage that is present. Sanding and wood filler can be used to repair minor damage however, major damage might require professional repair.

When the glass is removed, it's important to measure its height, width and thickness. The most effective method to do this is to take out the glazing beads that secure the unit. This is a delicate task that requires patience and care. double glazed sealed unit replacement and wear safety gear to avoid shards and slips.

The best way to begin is by removing the bottom bead from the glazing strip, with a chisel that is sharp or a an abrasive screwdriver with a wide blade. It is recommended to have someone to hold the sealed window unit as you remove all the beads. The unit is prone to be thrown off the frame and break.

Once all the beads have been removed, it's crucial to take careful measurements of the width, height and thickness of the unit that is currently in use. The measurements can be used to construct an appropriate replacement unit for your home. Additionally, it will also provide a guide for ensuring the new unit fits in the frame. It is crucial to ensure that the window fits correctly, as a mismatch will not only need the entire unit to be disassembled and rebuilt, but also reduce its performance. This is particularly true in Australia where homes are often exposed to extreme weather conditions.


Preparing the Frame

If you are replacing a fixed window, or a sliding one with a fixed or opening sash, be sure that the new window is the right size. UPVC frames have very little movement and double-glazed sealed units that is a few millimeters oversize will not fit. Measure carefully and consult a professional or the manufacturer's guide if necessary to ensure accurate measurements.

Remove the glass from the frame when you're sure that the replacement is of the correct size and is properly installed. Wear safety gear, like gloves and work in an area that is well-lit to avoid injury from glass fragments. Utilize a putty knife to cut off the glazing strips or beads that secure the glass to the frame from the perimeter of the pane. The glass is hard and you must be cautious to avoid sliding or stressing the frame.

Check that the frame can open and close smoothly when the new double-glazing unit sealed is installed. It should be a tight fit, but you are able to adjust it if you need to by removing or adding packers. If the frame is designed for a sliding glass door it is possible to add more packers on the top of the hinge and opposite corner to prevent the sash from catching when it opens.

Finally, clean the frame and remove any old sealant or glazing tape as required. Examine any damages and make small repairs with wood filler or sanding if needed. A final inspection and cleaning will prepare the frame for replacement, and will give it a fresh look for long-term protection against the harsh Australian climate.

Lifting the New Unit

Over time, double-glazed sealed units can develop problems like condensation between the panes or misting. This can reduce the efficiency of your windows which allows cold air to get in and warm air from your heater to escape, leading to the cost of energy and discomfort.

This kind of seal failure is usually caused by age or general wear and tear or harsh chemical cleaners that deteriorate the sealing material. Sometimes however, the reason can be attributed to the shrinking and expanding of the glass as a result of temperature changes and seasonal changes.

When the frame is clean and ready and clean, you can move the new unit onto the frame. This is a very exciting step since you've just improved your home's heating in the winter months and cooling in the summer, while decreasing your energy bills.

It's important to make sure the new piece fits in the frame prior to locking it to the frame. This phase is important to ensure that the frame isn't damaged and the glass.

If you use glazing tape or sealing tape on your windows, this is the best time to put a bead along the perimeter of the glass. This creates a strong barrier that will prevent air and moisture from getting into the window. Make sure to tighten the sealant carefully, ensuring it's secure but not tight enough to stress the glass or frame. Finally, give yourself an ointment for a job well done and then enjoy your newly-installed double-glazed window!

Secure the Unit

With the new unit seated perfectly in the frame, and a new layer of sealant covering its entire perimeter, this is the moment to mark the end of your work. The unit is now secure to hold up to Australia's varied weather which guarantees warmth in the winter months and coolness in summer. It's the moment when you can confirm the accuracy of your measurement and removal, which is a proof of a unit crafted according to precise measurements.

If a window is made of glazing beads or screws, attaching the new window to the frame requires an art of balancing tight enough to secure it and soft enough not to strain the glass. If it's too loose, the unit may lose its airtight seal. If it's not tight enough, it may damage the frame or warp material. Each screw must be placed in its original position, and rotated just enough to hold the unit securely without putting pressure too high.

This is the final stage in a project that will enhance the efficiency of a home's energy and comfort as well as its appearance. The moment your work is completed, with the new double-glazed unit safely seated in the frame, and a new bead adorning its perimeter.

The cavity that acts as an insulator between the panes of glass is filled either argon gas or a desiccant. Argon, unlike air, has a lower thermal conductivity which reduces heat transfer. Desiccants also absorb moisture from the air, preventing condensation and mould in the frame. The spacer bar is constructed of aluminum and is an essential component of the insulation system. Aluminium not only impedes heat transfer, but also helps keep the edge warm of the window insulated to prevent condensation.

Checking Your Work

When you've installed the new unit and sprayed an ounce of silicone sealant to the edge it is essential to let it sit and set. Don't disturb it! It will take at minimum four hours for the silicone sealant to attain its maximum strength and form an impenetrable wall. While you sit, take the time to visually evaluate your work and determine if you can detect any gaps or issues that could impact the performance or appearance of the unit.

It's also a good time to examine the seals and frame to see if there are any signs of damage. You can also determine if the whole window should be replaced. A damaged seal could have a huge impact on the efficiency of your home, leading to drafts and cold spots. It also allows ultraviolet rays to penetrate the house, causing fading of furniture and reducing the life of curtains and carpets.

If you are having any of these issues it is possible that your double glazing need to be replaced. Taking care of it quickly will reduce your energy bills and provide a more comfortable and relaxing home.

It is a complex and labor-intensive procedure that requires the correct equipment, precise measuring and careful preparation. It is not an DIY task and should only be handled by a professional in uPVC windows and doors who can ensure the proper fitting of the replacement unit, and keep your house safe from the elements. Their skill and experience will ensure that your double glazed unit is quiet and efficient blend of warmth during winter and coolness during summer, shielding your home from weather.
