Replacing Double Glazed Units
Replacing double glazed units is a home improvement project that can drastically reduce heat loss, increase noise insulation and lower heating costs. Modern coatings and argon/krypton filled units make them extremely energy efficient.
The new unit, crafted according to precise measurements, awaits its place and calls for attention and care. This is the moment that is a moment that stops the world and puts your efforts into perspective.
Removing the Old Unit
Removal of the old window is a crucial step to ensure that your new double glazed window is constructed to the exact measurements. Make sure to clean the frame of dust, dirt or old sealant and repair any damage that could be present. Small repairs can be made by using wood filler or sanding but major damage might require professional repairs.
After the glass has been removed, it is important to determine its width, height and thickness. This can be accomplished by removing the glazing beads that hold the unit. This is a delicate procedure that requires patience and caution. It is recommended to take your time and always use safety gear to protect yourself from unexpected shards glass and accidental slips.
Start by taking off the lower part of the glazing strip using the sharp end of a chisel or a wide-bladed, sharp screwdriver. Once the bead has been removed, it is advisable to ask for help from a person who can hold the sealed unit while you take out the remaining beads. The unit can easily be thrown off the frame and break.
After you have removed all the beads, it is crucial to measure the width, the height, and the thickness of the current unit. The measurement data can then be used to construct a replacement unit for your home. It can also be used as a guide to ensure that the new unit is constructed correctly for the frame. It is essential to make sure that the window is properly fitted, as a mismatch will not only need the entire unit to be taken apart and rebuilt, but also reduce the performance of the unit. This is particularly important in Australia as our homes are often subject to extreme weather conditions.
Preparing the Frame
If you are replacing an existing fixed sliding door or window using a fixed sash or opening sash, ensure that the new unit is of the proper dimension. UPVC frames offer only a small amount of movement and a double glazing unit that is a few millimeters too large will simply not fit. To ensure accurate measurements take care to measure accurately and seek the advice of an expert.
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. Be sure to work in a well-lit space and wear protective equipment, such as gloves, to avoid injury from shards of glass. Use a putty knife to pry the glazing strips or beads that hold the glass to the frame from around the edges of the pane. The glass is brittle and you must be careful not to slip or pulling the frame.
Verify that the frame will open and close easily when the double-glazing unit that is sealed is installed. You can adjust the fit if needed by removing or adding packing. For instance, if your frame is a sliding door you might need to add packers at the top of the hinge's side and in the opposite corners to stop the sash from catching or shaking when it opens.
Then, clean the frame. Remove any old glazing tape or sealant If needed. Examine any damage and make small repairs, if needed, using wood filler or sanding. The frame will be refreshed by a final clean and inspection and will be able to withstand Australia's harsh weather for years.
Lifting the New Unit
Over time, double-glazed sealed units (or a 'sealed unit' as it is more commonly called) may face problems like moisture between panes and/or misting. This can compromise the effectiveness of your windows and allow cold air to get in and warm air from your heater to escape, which can result in the cost of energy and discomfort.
This kind of seal failure is typically caused by aging, general wear and tears or harsh chemical cleaners that deteriorate the sealing material. Sometimes, the cause is due to shrinking and expansion of the glass during the changing seasons and changes in temperature within the home.
After the frame has been cleaned and prepared after which you can begin lifting the new unit into place. This is an exciting moment that you've made a real difference to your home, enhancing its comfort in winter and cooling in summer, whilst also helping to reduce your energy bill.
It's important to make sure the new unit is properly fitted in the frame prior to locking it to the frame. This is essential to avoid damaging the frame and the glass.
If your windows are fitted with glazing tape or sealant this is the perfect time to apply a small bead around the edges of the frame and glass, creating a strong barrier against air and moisture infiltration. Be sure to tighten the sealant in a controlled manner but not so much that it causes stress to the frame or glass. Enjoy your newly installed double-glazed windows, and give yourself a pat for an excellent job!
Securing the Unit
With the new unit seated snugly in the frame and a new layer of sealant covering its entire perimeter it is the moment to mark the end of your project. The unit is now secured to withstand Australia's varied weather conditions, providing for warm temperatures in winter and cool temperatures in summer. This is the moment when your meticulous measurements and removal are validated and a confirmation that the unit was crafted precisely to your specifications.
Whether window seal repairs uses glass beads or screws, attaching the new window to the frame is an art of balancing tight enough to hold it in place and soft enough not to stress the glass. If the frame is too loose, then the unit may lose its airtight sealing. If it's secure enough, it may damage the frame or warp material. Each screw must be able to locate its original position by turning only enough to ensure that the unit is held securely without putting pressure too heavily on it.
This is the last step in a transformational project that improves a home's comfort as well as energy efficiency and appearance. With the new double glazed unit sitting snugly within the frame, and securing a fresh bead of sealant around the perimeter it is the moment that signifies your work's completion.
The glass panes can be filled with argon or desiccant. In contrast to air, argon has much lower thermal conductivity and reduces heat transfer through glass. Desiccants also adsorb moisture from the air, preventing condensation and mould from the frame. The spacer bar, which is typically made of aluminium, is an essential part of the insulating system. The aluminum bar not only blocks heat transfer but also keeps the edges warm of the insulated window to prevent condensation.
Be sure to check your work
When you've put up the new unit and sprayed an ounce of silicone sealant around the edges, it is important to leave it alone to set - don't handle it! It takes at least 4 hours for it to reach its maximum force and create an impenetrable barrier. While you are waiting, take the time to examine your work visually and determine if you can identify any gaps or issues that could impact the efficiency or appearance of the product.
This is also a great moment to inspect the frame and seals for signs of damage that need attention, and to assess whether replacement of the entire window is needed. A faulty seal will significantly impact the efficiency of your home's energy use as it can lead to drafts and cold spots. It also allows UV rays enter the home which can cause furniture to fade and curtains and carpets to wear down faster.
If you're having any of these issues it is possible that your double glazing need to be replaced. If you take care of it promptly, it can lower your energy costs and create a more comfortable and relaxing home.
Replacing a double glazed sealed unit is a laborious and technical process that requires the appropriate equipment, meticulous preparation and precise measuring. It is not an easy DIY project and should be done by a specialist who has expertise with uPVC Windows and Doors. They can ensure that the replacement unit is installed correctly to shield your home from the elements. Their experience will ensure the double-glazed model you choose is both efficient and quiet offering warmth in winter and cooling in summer. This will help protect your home from the elements.
