Replacing Double Glazed Units
Replacing double glazed units is a home improvement project that can greatly reduce heat loss, increase insulation from noise and reduce heating bills. Modern coatings and argon/krypton filled units make them very energy efficient.
The new unit, which was built to exact measurements, is waiting for its time. It is a task that requires attention and precision. This moment stops the world and puts your work into perspective.
Remove the Old Unit
Removing the old unit is a critical step to ensure that the new double-glazed window is constructed to precise measurements. Carefully clean the frame of dust, dirt or old sealant, and then repair any damage that may be present. Wood filler and sanding may be used to repair minor damage however major damage could need professional repair.
Once the glass is removed, it's crucial to determine its width, height and thickness. This can be done by removing the glazing beads that hold the unit. This delicate process requires patience and care. Take your time, and wear safety gear to prevent slips and shards.
The best place to begin is by removing the bottom bead of the glazing strip with a chisel that is sharp or a sharp screwdriver with wide blades. It is recommended to ask someone to hold the window unit as you remove all the beads. This is because the unit could easily fall out of the frame and hit.
After removing all the beads, it is crucial to determine the width, height and the thickness of the existing unit. The measurement data can then be used to construct an appropriate replacement unit for your home. Additionally it will provide a reference for ensuring that the new unit is a good fit in the frame. This is important as an inadvertent misfit could result in the need to remove and put back together the entire window, but also affect the efficiency and performance of the window. This is especially important in Australia, where our homes are often exposed to extreme weather conditions.
Preparing the Frame
If you are replacing a fixed sliding door or window with an opening or fixed sash make sure that the new unit is the right dimension. UPVC frames have a very limited movement and double-glazed sealed units that is just a few millimeters oversize will not work. To ensure that measurements are accurate, measure carefully and consult an expert.
Once you have a clear understanding of the dimensions of your replacement, and are sure that it's properly fitted take the glass out of its frame. Make sure you work in a well-lit area and wear safety equipment such as gloves to avoid injury from glass shards. Make use of a putty blade to cut off the glaze stripes or beads that hold the glass in the frame from the edges of the pane. Avoid slipping on patio door seal replacement or straining the frame.
Verify that the frame will open and close smoothly when the double-glazing unit that is sealed is installed. You can adjust the fit as needed by adding or removing packing. For example, if the frame is a sliding door, you may have to add extra packers at the top of the hinge side and opposite corner to prevent the sash from getting caught or rattle when it opens.
Finally, clean the frame and remove any old sealant or glazing tape as required. Examine any damage and make small repairs if necessary by using wood filler or sanding. A final cleaning and inspection will prepare the frame for replacement, ensuring it will last for a an extended period of protection from Australia's harsh climate.
Lifting the New Unit
Over time, double-glazed sealed units (or a 'sealed unit' as it is commonly known) may face problems like moisture between panes and/or misting. This can affect the performance of your windows, allowing cold air to enter and warm air from your heater to escape, resulting in high energy bills and discomfort.
This type of seal failure generally occurs due to age, general wear and tear or harsh chemical cleaners that deteriorate the sealing material. Sometimes, the cause is due to the expanding and shrinking of the glass during the changing seasons and the temperature fluctuations within the home.
After the frame has been cleaned and prepared after which you can begin lifting the new unit into the right place. This is a thrilling step since you've just increased the efficiency of your home's heating during winter and cooling during the summer while also reducing your energy bill.
Before securing the unit it's important to ensure that the new unit fits properly into the frame. A little attention in this phase can prevent damage to the frame and also the glass.
If you are using 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 solid barrier that stops moisture and air from entering the window. Make sure to tighten the sealant carefully and ensure it's secure but not too tight to stress the frame or glass. Finally, give yourself a pat on the back for an excellent job, and enjoy your newly installed double-glazed window!
Securing the Unit
With the new unit sitting comfortably in the frame and a new layer of sealant covering its perimeter it is the moment that marks the end of your work. The unit is now secure to withstand Australia's varied weather conditions, providing for warmth in winter and cooling in summer. This is the moment when your meticulous measuring and removal is confirmed and a confirmation that the unit was built precisely to your specifications.
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 lose its airtight seal. If it's secure enough, it may damage the frame or warp material. Each screw must be placed in its initial position and rotated just enough to hold the unit securely without putting pressure too high.
This is the final stage 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 firmly seated within the frame, and securing the fresh sealant around its perimeter This is the moment to mark the end of your work.
The insulating cavity between panes of glass is filled with either argon gas, or a desiccant. Argon is, in contrast to air has a lower thermal conductivity, which decreases heat transfer. Furthermore the desiccant absorbs water in the atmosphere, to prevent condensation and mould from forming within the frame. The spacer bar is made of aluminium and is an essential component of the insulation system. The aluminium blocks the transfer of heat but also keeps the edge of the insulated glass warm to prevent condensation.
Verifying Your Work
When you've put up the new unit and sprayed the silicone sealant around the edges, it is important to leave it alone to set - don't handle it! It takes at least four hours for the silicone sealant to attain its maximum strength and create an impenetrable barrier. While you wait, evaluate your work to see whether there are any gaps or other issues that could impact the effectiveness or appearance.
It is also a great time to inspect the seals and frame to determine if there are any signs of damage and determine if the entire window should be replaced. A damaged seal can have a huge impact on the energy efficiency of your home, causing drafts and cold spots. It also allows UV rays enter the home which can cause furniture to fade and curtains and carpets to wear more quickly.
If you're experiencing any of these issues it's a sign that your double glazing is in need of replacement. It can help you save money on your energy bills, and also create a more peaceful and comfortable home.
Replacing a sealed double-glazed unit is a labor-intensive and technical process that requires the appropriate equipment, meticulous preparation and precise measurements. It is not an easy DIY project and should be done by a professional with expertise with uPVC Windows and Doors. They will ensure that the replacement unit is installed correctly to shield your home from the elements. Their expertise and knowledge will ensure that your double-glazed unit is quiet and efficient blend of warmth in the winter and coolness in summer, securing your home from the weather.
