15 Interesting Facts About Replacement Sealed Double Glazing Units That You've Never Heard Of
Replacing Double Glazed Units
Double glazed units can be substituted to cut down on heat loss and noise, and also reduce heating costs. With modern coatings and argon, or krypton gas fills they are also extremely energy efficient.
The new model, designed to exact measurements, awaits its time and requires attention and precision. This is the moment that will stop the world and puts your efforts into perspective.
Removal of the Old Unit
Removing the old unit is an essential step to ensure your new double-glazed window is built according to exact measurements. Make sure to clean the frame of dust, dirt or old sealant, and then repair any damage that might be present. Wood filler and sanding can be used to repair minor damage however major damage could need professional repair.
When the glass is removed, it's crucial to determine its height, width, and thickness. This can be done by removing the glass beads that hold the unit. This delicate process requires patience and caution. Be patient and wear safety gear to prevent slips and shards.
Start by removing the bottom of the glazing strip using a chisel that is sharp, or a wide-bladed screwdriver. After the bead is removed, it's recommended to ask for help from a person who can hold the sealed unit as you take out the remaining beads. The unit can easily fall off the frame and break.
Once all the beads have been removed, it is important to measure the dimensions of the width, height and thickness of the unit that is currently in use. The measurements can be used to accurately construct an appropriate replacement unit for your home. In addition, it will also provide a guide for ensuring the new unit is a good fit in the frame. It is crucial to ensure that the window fits correctly, as a mismatch will not only require the whole unit to be dismantled and reassembled but will also affect its performance. This is especially important in Australia where homes are frequently 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 correct dimension. UPVC frames have a very limited movement and double-glazed units that is just a few millimeters oversize is not going to fit. Measure carefully and consult a professional or the manufacturer's guide in order to make sure you get accurate measurements.
Once you have a clear idea of the dimensions of your replacement, and are confident that it's properly fitted remove the glass from its frame. Be sure to work in a well-lit location and wear protective equipment like gloves to prevent injuries from glass shards. Use a putty blade to cut off the glaze strips or beads that secure the glass to the frame from the edges of the pane. The glass is brittle and you must be careful not to slip or straining the frame.
Check that the frame can open and close smoothly when the new double-glazing unit sealed is installed. You can adjust the fit as needed by adding or removing packing. For instance, if your frame is a sliding door you may have to add additional packers on the hinge's side and in the opposite corner to prevent the sash from getting caught or shaking when it opens.
Finally, clean the frame and take off any old sealant or glazing tape as required. Assess any damage, and make small repairs if necessary using wood filler or sanding. The frame will be rehabilitated by a final clean and inspection, allowing it to 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 often known) may develop issues like moisture between panes and/or misting. If this happens, the effectiveness of your window is diminished, letting cold air in and letting warm air from your heating system out which can result in high energy bills and decrease in comfort.
This kind of seal failure usually occurs due to aging general wear and tear, or harsh chemical cleaners that degrade the sealing material. Sometimes, the cause is due to shrinking and expansion of the glass in the changing seasons and temperature changes in the home.
After the frame is cleaned and ready after which you can begin lifting the frame into place. This is a very exciting step as you have just improved the heating of your home in the winter months and cooling in the summer, while decreasing your energy bills.
It's important to make sure the new unit fits correctly into the frame prior to securing it to the frame. A little care in this phase will help prevent any damage to the frame, as well as the glass.
If you use glazing tape or sealing tape on your windows, this is the best time to put a small amount of the tape along the edges of the glass. This creates a strong barrier that blocks air and moisture from getting into the window. Tighten the sealant with care making sure it's secure, but not tight enough to cause stress on the frame or glass. Enjoy your newly installed double-glazed windows and reward yourself a pat on the back for the job well done!
Secure the Unit
This is the moment when the work is done. The unit will be firmly seated in the frame, and a fresh sealant will be applied around the perimeter. The unit is now secured to hold up to Australia's varied weather, a guarantee of warmth in winter and coolness during summer. This is when your meticulous measurements and removal are validated and a confirmation that the product was designed to exact dimensions.
Whether a window uses glazing beads or screws, fixing the new unit to the frame is an intricate balance between being secure enough to hold it in place and soft enough to not stress the glass. If it's too loose, the unit might be unable to seal its airtight seal. If it's too tight, it might cause damage to the frame or weaken the material. Each screw should be put in its original place, and rotated just enough to ensure that the unit is held securely without putting too much pressure on it.
This is the last step in a transformational project that enhances the comfort of a home and energy efficiency as well as its appearance. The moment you are completed, with the new double-glazed unit securely placed in the frame and a new bead adorning its perimeter.
The insulating cavity between the panes of glass is filled with either argon gas, or a desiccant. In contrast to air, argon has less thermal conductivity, which reduces heat transfer through glass. Desiccants also absorb moisture from the air, which prevents condensation and mould in the frame. The spacer bar is constructed of aluminum and is an essential part of the insulation system. The aluminium not only prevents heat transfer but also keeps the edge warm of the insulated window to avoid condensation.
Checking Your Work
When you've installed the new unit and applied an ounce of silicone sealant around the edges It is crucial to let it sit and set. Don't touch it! It takes at least 4 hours for it to reach its full strength and provide an impervious barrier. While you sit, take the time to examine your work visually and see if you are able to spot any gaps or other issues that could impact the effectiveness or appearance of the product.
This is also a good moment to inspect the seals and frame for signs of damage that need attention, and to assess whether replacement of the entire window is needed. A damaged seal can have a significant impact on your home's energy efficiency and can cause drafts or cold spots. It also lets ultraviolet rays in to the home and cause furniture to fade, and curtains and carpets to wear down more quickly.
If you're experiencing any of these problems it's an indication that your double glazing is in need of replacement. It will help you save money on your energy bills, and create a more relaxed and comfortable home.
