This moment will stop the world and puts your work into perspective. Removing the Old Unit It is crucial to remove the old unit to ensure that the new double-glazed window has been made to the exact measurements.

Additionally, it will also give you a direction to ensure that the new unit fits in the frame. This is important as an inadvertent misfit could result in the need to take down and put back together the entire window, but it will also impact the efficiency and performance of the window. This is especially important in Australia where homes are often exposed to extreme weather conditions. Preparing the Frame Whether you are replacing a fixed window, or a sliding door with a fixed or opening sash, make sure your new window is of the correct size. UPVC frames offer very little space for movement and a double glazing unit that is even a few millimeters too large will simply not fit. To ensure precise measurements, measure carefully and consult an expert. Once you have a clear understanding of the dimensions of the replacement and are confident that it's properly fitted take the glass out of its frame. Make sure you work in a well-lit space, and wear safety equipment, such as gloves, to avoid injury from glass shards. Use a putty knife pry the glazing beads or strips that hold the glass in the frame, from around the perimeter of the pane. The glass is brittle and you must be cautious to avoid sliding or pulling the frame. Check that the frame can open and close smoothly when the new double-glazing unit sealed is installed. You can alter the fit as needed by removing or adding packing. For example, if the frame is a sliding door you might need to add additional packers on the hinge's side and in the opposite corner to prevent the sash from getting caught or rattle when it opens. Finally, clean up the frame and take off any old sealant or glazing tape, as needed. Check for any imperfections and make minor repairs by using wood filler or sanding, if required. The frame will be refreshed by a final cleaning and inspection so that it can stand up to the harsh Australian weather for many years. Lifting the New Unit Over time, double-glazed sealed units can experience problems such as condensation between the panes or misting. This can affect the performance of your windows and allow cold air to pass through and warm air from your heater to escape, resulting in the cost of energy and discomfort. This kind of seal failure typically occurs due to aging or general wear and tear or harsh chemical cleaners that deteriorate the sealing material. Sometimes, however, the cause could be due to the shrinking and expanding of the glass as a result of temperature changes and seasonal changes. After the frame is cleaned and ready and sanded, you can begin lifting the new unit in the right place. This is an exciting moment, as you've just created a positive impact on your home, increasing its warmth in the winter months and cooling it in summer, and aiding in reducing your energy bill. It is crucial to ensure that the new piece fits into the frame prior to securing it in place. This is essential to ensure that the frame isn't damaged and the glass. If your windows have glazing tape or sealant this is the perfect time to apply a small bead around the perimeter of the frame and glass to create a solid protection against air and moisture infiltration.

It's the moment when you can confirm the precision of your measuring and removal, a proof of a product that has been designed to exact measurements. 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 unit may be unable to seal its airtight. If it's not tight enough, it could cause damage to the frame or warp material. Each screw must find its original location and rotate just enough to ensure that the unit is held securely without putting pressure too heavily on it.

With the brand new double-glazed unit sitting snugly within the frame, and securing the fresh sealant around the perimeter it is the moment that signifies the completion of your project. The cavity between the glass panes is filled with the gas argon or with a desiccant. Argon, unlike air, has a lower thermal conductivity, which can reduce heat transfer. Furthermore the desiccant absorbs moisture from the air, preventing condensation and mould from building up within the frame. The spacer bar is constructed of aluminium and is an essential part of the insulation system. The aluminium prevents the transfer of heat but also keeps the edge of the glass insulated warm to avoid condensation. Be sure to check your work It is essential to leave the silicone sealant to set once you have installed the new device. It will take at minimum four hours for the silicone sealant to attain its maximum strength and create an impenetrable wall.
