Replacing Double Glazed Units
Double-glazed units can be replaced to reduce heat loss and noise, as well as reduce heating costs. Modern coatings and argon/krypton gas filled units make them extremely energy efficient.
The new unit, crafted according to precise measurements, awaits its time and requires attention and precision. This moment stops the world and puts your work into perspective.
Removal of the Old Unit
Removing the old unit is an essential step to ensure that your new double-glazed window is constructed to the exact measurements. Make sure to clean the frame of any dirt, dust or old sealant, and then repair any damage that could be present. Repairs of minor amounts can be made with wood filler or sanding however major damage could require professional repair.
Once the glass has been removed, it is necessary to determine its width, height and thickness. This can be accomplished by removing the glass beads that support the unit. This is a delicate task that requires patience and prudence. Be patient and wear safety gear to prevent slips and shards.
The best way to begin is by removing the bottom bead of the glazing strip, using a sharp chisel or an abrasive screwdriver with a wide blade. After the bead is removed, it's recommended to get help from someone to hold the sealed unit while you take out the remaining beads. This is because the unit can easily be thrown out of the frame and smash.
After all the beads have been removed, it is essential to carefully measure the width, height and thickness of the existing unit. The measurement data can then be used to accurately construct an appropriate replacement unit for your home. It can also be used as a guide to ensure that the new unit is constructed properly for the frame. It is essential to ensure that the window is properly fitted because a mismatch will not only need the entire unit to be dismantled and reassembled, but it will also impact the performance of the unit. This is particularly true in Australia where homes are frequently exposed to extreme weather conditions.
Preparing the Frame
If you are replacing a fixed or fixed window or a sliding one with a fixed or opening sash, be sure that the new window is the correct size. UPVC frames allow very little space for movement and a sealed double glazing unit that is even a few millimeters too big is likely to not fit. Be sure to measure carefully and consult a professional or manufacturer's guide in order to make sure you get accurate measurements.
Remove replace double glazing seals from the frame after you're sure that the replacement is the right size and has been correctly installed. Make sure you work in a well-lit location and wear protective equipment such as gloves to avoid injury from glass shards. Make use of a putty blade to cut off the glazing strips or beads that secure the glass into the frame from the perimeter of the pane. The glass is brittle, and you should be careful to avoid slipping or pulling the frame.
Check that the frame can be opened and closed smoothly after the double-glazing unit that is sealed is installed. It should be a tight fit, however you can adjust it if you need to by removing or adding packers. For example, if the frame is a sliding door, you may have to add extra packers on the hinge's side and in the opposite corner to prevent the sash from colliding or shaking when it opens.
Then clean the frame. Remove any old glazing tape or sealant If needed. Examine any damage and make minor repairs if necessary by using wood filler or sanding. The frame will be rejuvenated by a final cleaning and inspection so that it can endure 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) can develop issues like moisture between panes and/or misting. This can reduce the efficiency of your windows, allowing cold air to pass through and warm air from your heater to escape, which can result in uncomfortable energy bills and discomfort.
This kind of seal failure is typically caused by aging or general wear and tear or harsh chemical cleaners that deteriorate the sealing material. However, sometimes the cause is simply down to expanding and shrinking of the glass in the changing seasons and the temperature fluctuations in the home.
After the frame is cleaned and ready, you can start lifting the new unit into place. This is a thrilling step, as you've just made a significant improvement to your home, increasing its warmth in the winter months and cooling it in summer, and helping reduce the cost of energy.
Before securing the unit, it is essential to make sure that the new unit is properly fitted into the frame. A little care during this stage will help prevent any damage to the frame, and also the glass.
If you use glazing tape or sealing tape on your windows, now is the best moment to apply a small amount of the tape along the edges of the glass. This creates a solid barrier that stops moisture and air from entering the window. Be sure to seal the sealant with care but not so much that it strains the frame or glass. Don't forget to give yourself an ointment for an excellent job, and enjoy your new double-glazed window!
Secure the Unit
This is the moment when your work is complete. The unit will be securely seated in the frame, and a new sealant will be applied around its perimeter. The unit is now secure to withstand Australia's varied weather conditions, providing for warmth in winter and cooling in summer. It's the moment when you can confirm your careful measuring and removal, a confirmation of a product that has been designed to exact measurements.
If a window is made of glass beads or screws attaching the new window to the frame is a delicate balance between tight enough to secure it and soft enough to not stress the glass. If it's too loose, then the window could be unable to seal its airtight. If it's too tight, it could cause damage to the frame or even warp the material. Each screw must be put in its initial position and rotated just enough to secure the unit without putting too much pressure on it.
This is the last step in a transformational project that enhances the comfort of a home as well as energy efficiency and appearance. When your work is completed, you will have a brand new double-glazed unit firmly placed in the frame and a fresh bead around the perimeter.
The cavity that acts as an insulator between the panes of glass is filled with either argon gas or a desiccant. As opposed to air, argon is significantly 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 is constructed of aluminium and is a vital part of the insulation system. The aluminum blocks the transfer of heat but also keeps the edge of the insulated glass warm to avoid condensation.
Verifying Your Work
After you've put in the new unit and sprayed an ounce of silicone sealant to the edge it is essential to leave it alone to set - don't handle it! It takes at least four hours for the silicone sealant to reach its maximum strength and create an impenetrable barrier. While you wait, visually evaluate your work to see whether there are any gaps or other issues which could affect the efficiency or appearance.
It is also a good time to examine the frame and seals for signs of damage that require attention, and also to determine whether replacement of the entire window is required. A damaged seal can have a significant impact on the efficiency of your home's energy usage, causing drafts or cold spots. It also allows UV rays enter the home which can cause furniture to fade and carpets and curtains to wear out faster.
If you're having any of these issues it is possible that your double glazing require replacement. Making it a priority to replace it immediately can lower your energy costs and create a more comfortable, relaxed home environment.
It is a complicated and labor-intensive procedure that requires the correct equipment, precise measurement and careful preparation. It is not a DIY job, and should only be completed by a professional in uPVC windows and doors who can ensure the proper fitting of the replacement unit, to keep your house safe from the elements. Their expertise and knowledge will ensure that your double glazed unit is quiet and effective blend of warmth in winter and coolness in summer, protecting your home from weather.
