Replacing Double Glazed Units
Replacing double glazed units is a home improvement task that can greatly reduce heat loss, increase the insulation of noise and reduce heating costs. Modern coatings and argon/krypton filled units make them extremely energy efficient.
The new unit, which was built to exact measurements, is awaiting its place. It needs care and accuracy. This is the moment that halts time and puts everything in perspective.
Remove the Old Unit
Removing the old unit is a crucial step that will help ensure the new double-glazed window is constructed to the exact measurements. Clean the frame carefully to remove any 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 need professional repair.
After the glass is 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 delicate process requires patience and caution. It is recommended that you take your time and make sure to wear safety gear to safeguard yourself from unexpected shards of glass and accidental slips.
Start by removing the top of the glazing strip using the sharp end of a chisel or a wide-bladed screwdriver. After the bead is removed, it is recommended to get help from someone who can hold the sealed unit as you remove the remaining beads. This is because the unit can easily fall out of the frame and smash.
After removing all beads, it is crucial to measure the width, the height and the thickness of the current unit. The measurements can be used to precisely design a replacement unit for your home. Additionally, it will also provide a reference for ensuring that the new unit will fit into the frame. It is important to ensure that the window fits correctly because a mismatch will not only require the entire unit to be disassembled and reassembled, but it will also impact the performance of the unit. This is especially important in Australia where homes are often exposed to extreme weather conditions.
Preparing the Frame
If you are replacing a fixed sliding door window that has an opening or fixed sash make sure that the new unit is of the correct size. UPVC frames have very little movement, and double-glazed units that is a few millimeters larger than the original will not fit. To ensure precise measurements make sure you measure with care and seek the advice of a professional.
Once you have a clear idea of the dimensions of your replacement, and you are sure it is correctly 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. Utilize a putty knife to cut off the glaze strips or beads that secure the glass to the frame, and remove them from the perimeter of the pane. The glass is brittle and you must be careful not to slip or pulling the frame.
Check that the frame can open and close easily when the new double-glazing unit sealed is installed. You can alter the fit by removing or adding packing. For instance, if your frame is a sliding door, you may need to add additional packers on the hinge's side and in the opposite corner to prevent the sash from catching or shaking when it opens.
Finally, clean the frame and get rid of any old glazing tape or sealant as required. Examine any damages and make small repairs by using wood filler or sanding if necessary. A final clean and inspection will make the frame ready for replacement, rejuvenating it for long-term 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 develop problems like moisture between panes or misting. If this happens, the effectiveness of your window is compromised by letting cold air in and allowing warm air from your heating system out which can result in higher energy bills and a decrease in comfort.
This type of seal failure typically occurs due to aging or general wear and tear or harsh chemical cleaners deteriorating the sealing material. Sometimes, the cause is simply down to shrinking and expanding of the glass in the changing seasons and temperature changes in the home.
When the frame is clean and ready and clean, you can move the new unit into place. This is an exciting moment as you've increased the efficiency of your home's heating during the winter months and cooling in the summer while also reducing your energy bill.
Before securing the unit it is essential to ensure that the new unit is properly fitted into the frame. A little care during this stage can help avoid any damage to the frame, and also the glass.
If you have glazing tape or sealing tape on your windows, this is the best time to apply a bead along the perimeter of the glass. This creates a solid barrier that blocks air and moisture from getting into the window. Apply the sealant with care making sure it's secure, but not tight enough to stress the glass or frame. Finally, give yourself a pat on the back for an excellent job, and then enjoy your newly-installed double-glazed window!
Secure the Unit
With the new unit seated perfectly in the frame, and a fresh bead of sealant covering its perimeter This is the moment to mark the end of your work. The unit is finally secured to hold up to Australia's varied weather and ensure warmth in the winter months and coolness in summer. This is the moment the precise measurements and removal are validated as a proof that the unit was built to exact dimensions.
It is important to find the right balance between the need to secure the unit without stressing the glass. If it's too loose, the unit may be unable to seal its airtight seal. If it's secure enough, it could cause damage to the frame or warp material. Each screw must find its original place, turning just enough to hold the unit firmly without applying undue pressure.
This is the last step in a transformational plan that improves a home's comfort, energy efficiency, and appearance. With the new double-glazed unit snugly seated in the frame and secured with an all-new layer of sealant around the perimeter it is the moment that signifies the completion of your project.
The insulating cavity between the panes of glass is filled with either argon gas, or a desiccant. Argon is, unlike air is a bit less thermal conductivity, which decreases heat transfer. Furthermore, repairmywindowsanddoors adsorbs moisture from the air, to prevent condensation and mould from growing within the frame. The spacer bar, which is typically made of aluminum, is an essential component of the insulation system. Aluminium not only impedes heat transfer but also keeps the edges warm of the window insulated to prevent condensation.
Checking Your Work
When you've installed the new unit and put the silicone sealant around the edge It is crucial to allow it to set - don't handle it! It will take at least 4 hours for it to attain its full strength and provide an impenetrable barrier. While you wait, take the opportunity to examine your work visually and determine if you can spot any gaps or other issues that could affect the efficiency or appearance of the product.
This is also a great time to check the frame and seals for signs of damage that require attention, and to determine whether replacement of the entire window is required. A damaged seal could cause a significant impact on the energy efficiency of your home, causing cold spots and drafts. It also allows ultraviolet rays to penetrate the home, causing fade of furniture and reducing the lifespan of carpets and curtains.
If you're having any of these issues it is possible that your double glazing require replacement. If you take care of it promptly, it will lower your energy costs and create a more pleasant and relaxing home.
It is a complicated and labor-intensive process that requires the appropriate equipment, precise measuring and careful preparation. It is not a DIY task, and should be carried out by a specialist in uPVC windows and doors who can ensure the proper fitting of the replacement unit, and keep your house safe from the elements. Their experience and expertise will ensure that your double glazed unit is a quiet and efficient blend of warmth in the winter and coolness in summer, shielding your home from the elements.
