Replacement Double Glazed Units
Double glazed units, or sealed units as they're also known, can get worn out over time. This occurs when the insulating properties of the gasses that insulate the glass panes break down.
If a window has fallen down it's important to replace the window to ensure your home is well-insulated and energy efficient. The task is simple and easy to accomplish at home.

If the window has been properly installed, the new window will be firmly seated and will fit comfortably within the frame. If the new unit isn't of the same thickness as the older one, then you might need to alter the "packers" (usually red or blue slips of plastic) within the frame to ensure that it is properly placed. Consult your installer or the instructions of the manufacturer if you're not sure.
A high-quality replacement double-glazed sealed unit is made to the highest standards and will fit into your frame with the least amount of hassle. But, even a tiny mistake could have a huge impact on the performance of your window, and should be examined carefully.
Modern double glazed units are a great energy efficient addition to any home. They use the argon gas between the panes in order to insulate and reduce the amount of heat that can escape your property during cold weather.
However, sometimes these units can fail or have issues with their seals. This usually occurs when moisture enters the air cavity of the glass, causing condensation between the panes. The condensation in your window is not only unsightly but also affects the efficiency of the glazed unit.
Condensation can be caused by a range of causes. The best method to test for it is to look for a foggy or hazy appearance between your window panes. This indicates that the seal between the two panes of glass has been broken and moisture is flowing into your living spaces.
The first step to take is to remove the glazing beads around the edges of your window. It can be a bit difficult and messy, however it's worth the effort because you will be able to access the gasket for wedges that keeps your glass in place. You'll need to take off the beads with care so that they don't break and it is often recommended to ask for assistance at this point. After the beads have been removed, allow the sealed unit to fall slightly out of the frame. With a helper hold it in place while you measure it accurately length, width and the thickness. This is crucial because it will determine the size of the wedge gasket you will need to cut for the brand new double-glazed sealed unit.
Checking
Double glazing units or sealed units as they are commonly called they can break down over time. This normally occurs due to a breach in the seal, which allows condensation and moisture to enter the space between the panes. This can affect the capacity of the window to keep cold air out, warmth generated by the home's heating in and solar gain from the sun's energy inside.
The failure of seals can cause draughts in the home. Double glazed windows should be checked frequently for indications of failure. If you notice moisture or mist forming between the glass, it is an indication that the seal is failing and a replacement unit must be installed.
It is crucial to replace the sealed unit with the proper size. The uPVC frames that the sealed unit sits in have little tolerance for movement, so even just a few millimetres over could affect the performance of the window. Consult a professional or the instructions provided by the manufacturer to ensure that you purchase the right size.
Place the new unit into the frame with the help of a friend. This should be done in a secure place as the glass can break if it falls out. After the sealed unit is secured in the frame, reattach any packers on the bottom of frame and then put the glazing beads back into their original position. After you've completed this make sure you give the window an extensive visual inspection to ensure that there aren't any gaps and that it isn't misaligned.
You may need to add a small amount of sealant around the edges of the frame in order to prevent it from moving. It is recommended to check the thickness of the glass unit. Double-glazed units come in various thicknesses. If you choose the wrong one, it can have a negative impact on the u value of your home.
Sealing
Double glazing can improve the thermal efficiency of your home, and offer better acoustics. However, with time, the glass's seals can get worn out, leading to misty windows and a decrease in performance. In these instances replacement is required. It is a good idea to work with a double glazing professional who can assist you in selecting the most suitable glass products, make precise measurements and ensure proper installation.
When replacing a sealed unit the first thing to do is clean the frame. You can make use of an old paintbrush (4 inches is the ideal size) to sweep the frame out to remove dust and cobwebs that have built up within the frame over time. It's a great idea to clean the new seals once the frame has been cleaned. It is the easiest way to remove the wedge gaskets from the friction joint by placing your fingers along the edge of the gasket and pulling it away. Note down how long you need your new seals. This will assist when cutting them.
The installation of the sealed unit is simple after the gaskets and frame have been cleaned. To ensure the best results when doing this it's a good idea to cut off the beads (the UPVC frame clips that support the glass) and then take measurements of these. This will ensure the seal is built to the correct dimensions and ensure there are no gaps around it.
Once the beads are back in their place, you can insert the top bead and then work your way round to the other three. You should be careful not to touch the sealed units for a few minutes afterward, as the silicone sealant needs time to set and harden before you are able to handle it again. I typically leave it for about 6 hours prior handling, but this can depend on the silicone sealant's setting time.
Finishing
The sealing and finalization of the project is now necessary once the double-glazed unit has been installed securely within its frame. This step is not just an aesthetic finish to the project, it also signifies that your home will be prepared to withstand the elements after the new, secure guardian is in place.
The first step is to clean the frame, carefully removing any glazing beads or strips that secured the old glass. The frame is then cleaned of dirt, old sealant and glazing tape. This process also rejuvenates either the frame made of timber or aluminium. This is also the moment to make any small repairs using wood filler and sanding, if necessary. For more serious damage it is recommended to seek out an expert.
Next, the spacer tubes are filled with desiccants to adsorb any moisture that may be trapped in-between the two panes of glass in the course of manufacture or later on. This is a typical procedure for units with warm edges. Thermoseal Group stocks a range of desiccants and manual or automated dispensers for desiccant.
After the spacers are filled, the glass is sealed with a highly-performing silicone designed to withstand Australia's harsh environment. This sealant creates a tight barrier that is both strong and flexible capable of expanding and contract without becoming fragile or breaking. It is crucial to choose the correct thickness as any gaps could affect thermal performance. Ask a professional for advice or refer to the manual of the manufacturer for more information on the thickness you should use.
The final step is adding secondary sealant. This is usually polyisobutylene or a similar material. It's applied to the edges of the frame's exterior which creates a secondary seal able to repel moisture and prevent air penetration and improve energy efficiency.
Then, the frame is finished with aluminum cladding. This is a protective coating that is able to withstand the elements, keeping your frame looking new for years to come. It's a wise investment in the long-term integrity of your home's frame particularly in the case period or federation homes where wooden frames are susceptible to decay and rot.
