A The Complete Guide To Replacement Sealed Double Glazing Units From Start To Finish
Replacing Double Glazed Units
Double-glazed units can be replaced to lessen noise and heat loss, and also reduce heating costs. With modern coatings and argon or krypton gas fills, they are very energy efficient.
The new model, designed according to precise measurements, awaits its moment and demands attention and care. This is the moment when you stop the clock and puts everything into perspective.
Removing the Old Unit
It is crucial to remove the old unit in order to ensure that the new double-glazed window has been made to the exact measurements. Clean the frame carefully to get rid of dust, dirt, or old sealant. Repair any damage that may be present. Wood filler and sanding may be used to repair minor damage however, major damage might need professional repair.
After replacement seals for upvc windows has been removed, it's crucial to measure its height, width, and thickness. This can be accomplished by removing the glass beads that hold the unit. This delicate procedure requires patience and prudence. It is recommended that you take your time and 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 a sharp chisel, or a wide-bladed screwdriver. After the bead is removed, it is recommended to get help from someone to hold the sealed unit while you remove the remaining beads. The unit could fall off the frame and break.
After removing all the beads, it is important to determine the width, the height, and the thickness of the existing unit. The measurement data can then be used to precisely design an appropriate replacement unit for your home. In addition it will give you a direction to ensure that the new unit is a good fit in the frame. It is crucial to ensure that the window fits correctly because a mismatch will not only require the entire unit to be taken apart and reassembled but will also impact its performance. This is particularly relevant in Australia where homes are often subject to extreme weather conditions.
Preparing the Frame
If you are replacing a fixed sliding door window that has an opening or fixed sash, ensure that the new unit is of the right size. UPVC frames offer very little space for movement and a double glazing unit that is even a few millimeters too big will not be able to fit. Measure carefully, and consult a professional or manufacturer's guide if necessary to ensure accurate measurements.
Once you have a clear idea 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 location and wear protective equipment such as gloves to avoid injury from shards of glass. Make use of a putty blade to remove the glaze beads or stripes that secure the glass in the frame from the perimeter of the pane. You should avoid slipping the glass or straining frame.
Check that the frame can open and close easily when the new sealed double-glazing unit is installed. You can adjust the fit if needed by removing or adding packing. If the frame is for sliding glass doors, you might need to add packers to the top of the hinge and the opposite corner in order to prevent the sash catching when it opens.
Then clean the frame. Remove any old sealant or glazing tape If needed. Check for any imperfections and make minor repairs using wood filler, or sanding if needed. The frame will be refreshed by a final cleaning and inspection, allowing it to endure the harsh Australian 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 issues such as moisture in-between panes and/or misting. This can affect the performance of your windows which allows cold air to pass through and warm air from your heater to escape, resulting in uncomfortable energy bills and discomfort.
This type of seal failure is typically caused by aging general wear and tear or harsh chemical cleaners that damage the sealing material. Sometimes however, the cause can be attributed to the shrinking and expanding of the glass due to temperature fluctuations and seasonal changes.
When the frame is cleaned and ready and clean, you can move the new unit up into its place. This is an exciting step as you have just improved your home's heating in the winter months and cooling in the summer while also decreasing your energy bills.
It is essential to ensure the new unit is properly fitted into the frame before securing it in place. This is crucial to avoid damaging the frame and the glass.
If you have glazing tape or sealing tape on your windows, now is the perfect moment to apply a small amount of the tape along the edges of the glass. This creates a strong barrier that stops air and moisture from entering the window. Apply the sealant with care and ensure it's secure but not tight enough to stress the glass or frame. Then, give yourself a pat on the back for an excellent job, and enjoy your newly installed double-glazed window!
Secure the Unit
This is the time when the work is done. The unit will be firmly seated in the frame, and a fresh sealant will be applied to the perimeter. The unit is now secured to withstand Australia's diverse weather conditions, providing for warm temperatures in winter and cool temperatures in summer. This is when your meticulous measurements and removal is validated as a proof that the product was designed to exact dimensions.
It is important to find the perfect balance between the need to secure the unit without stressing the glass. If it's too loose, the unit may lose its airtight seal. If it's too tight, it might damage the frame or warp the material. Each screw must find its original place and rotate just enough to hold the unit firmly without putting pressure too heavily on it.
This is the final stage in a transformational project that enhances the comfort of a home as well as energy efficiency and appearance. With the new double glazed unit sitting snugly in the frame and secured with an all-new layer of sealant around the perimeter, this is the moment that marks the completion of your project.
The cavity between the glass panes can be filled with argon or desiccant. Argon is, unlike air has a lower thermal conductivity, which can reduce heat transfer. Additionally, a desiccant adsorbs water in the atmosphere, stopping mould and condensation from building up in the frame. The spacer bar is constructed of aluminum and is a vital part of the insulation system. The aluminum blocks the transfer of heat but also keeps the edge of the glass that is insulated warm to avoid condensation.
Be sure to check your work
When you've put up the new unit and sprayed a bead of silicone sealant to the edge, it is important to allow it to set. Don't disturb it! It will take at minimum four hours for the silicone sealant to reach its maximum strength and create 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 effectiveness or appearance of the device.
It is also a good time to examine the seals and frame for signs of damage that require attention, and to assess whether replacement of the entire window is needed. A damaged seal can have a huge impact on the energy efficiency of your home, leading to cold spots and drafts. It can also let ultraviolet rays in to the home which can cause furniture to fade, and curtains and carpets to wear out faster.
If you're experiencing any of these issues it is possible that your double glazing need to be replaced. It can help you save money on your energy bills and will create a more relaxing and comfortable home.
It is a complex and labor-intensive process that requires the appropriate equipment, precise measurements and careful preparation. It is not a DIY project and should be handled by a specialist who has prior experience working with uPVC Windows and Doors. They can ensure that the replacement unit is fitted 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 against the weather.
