Are Double Glazing Sealed Unit Replacement The Greatest Thing There Ever Was?
What to Look For in a Double Glazing Sealed Unit Replacement
Double glazing, or sealed units as they are commonly referred to, can fail in time. This normally manifests as a draft in the home.
The process of lifting the new unit into position is a task that requires precision and care. Fitting the unit is an indication of how well you've prepared and will ensure the comfort and efficiency you expect at home.
Measure
Over time, double glazing units can begin to fail. This typically manifests as a draught inside the unit or a loss of airtight seal. This is due to the fact that with time, the gas (normally inert Argon) in the panes may leak out due to shrinkage of the sealing material. The degrading of the seal can be caused by environmental factors like exposure to direct sunlight or by making use of powerful chemical cleaning products which can damage the glass and cause damage to the seal.
When a seal fails it can cause an uncomfortable feeling in a home and it is not uncommon to notice a difference in the energy efficiency of a home due to the failure of a seal. It is crucial to perform an inspection of your double-glazing every now and then.
In addition to checking visually for signs of damage, the other main indication is a feeling of the room is draughty. This is the initial sign of the need for a replacement double-glazed unit, as it is hard to fix the problem after it has been established.
When replacing a double-glazed sealed unit, it is essential to accurately measure the size of the existing window. This is due to the UPVC frames they sit in are not tolerant of movement, and if the new unit is too large, it won't fit. To ensure that it fits it is crucial to remove the beads and measure them. This will ensure that the new sealed unit is made according to the right size. You can purchase replacement UPVC frame beads online from suppliers who provide a variety of warm edge options such as steel and aluminium.
Remove
If your double-glazed windows are showing signs of condensation, it is likely that the seal has failed. This can be easily replaced with a new unit that will help to make your home more energy efficient, saving your money on heating bills and preserving the building's fabric.
You should remove the old glass before you begin work. This will ensure that the new pane will fit perfectly. You should also examine the frame to make sure it is strong enough for the new pane.
Start by opening any casement windows or vents within the frame so that you can see the edge of the unit. Then, place your calipers on the frame, clipping them against the existing unit on each side to determine the thickness. This will tell you the dimensions of the newly sealed unit and allow you to order it according to the exact measurements.
Utilize a utility knife to carefully cut the adhesive strip that holds the window in place. Once you've removed the strip, gently pry the glass away from the frame with the help of a shovel or putty knife. Remember that the glass is brittle and can break if you try to force it. Be careful not to scratch or damage the frame or the sealant.
Clean and prepare the frame for the double-glazed sealed unit. If you're installing a newly sealed unit, select an adhesive made of silicone that can stand up to Australia's extreme weather conditions without deteriorating into flaky or brittle. A high-quality silicone sealant is also watertight, securing your property from moisture infiltration and making for the most durable, sturdy finish.
Clean
Over time, the inside of double-glazed windows may appear opaque or foggy. This is a sign that the seals are not working and the window should be replaced.
Misted glass is typically caused by condensation that accumulates between the two panes of glass. This can cause the window to become fogged and also lead to the build up of stained areas between the panes. The only solution to eliminate the condensation is to replace the window.
After taking the old unit off, the frame can then be cleaned and prepared for a replacement double-glazed window that is sealed. Depending on the style of the window, it might be necessary to prime or paint the window before applying the sealant. It is essential that any paint or varnish is allowed to completely dry before the sealant is applied.
If the existing window was secured with beads then the beads must be removed before a replacement unit can be installed. You can accomplish this using an screwdriver or chisel. Place the blade on the edge of the bead and gently pry it away from the frame. To avoid damaging the window frame, make several shallow cuts instead of one deep cut. After you have removed the bead frame, carefully lift it off of the glass and set it aside.
With a knife or tool, cut off any remaining sealant off of the bottom of the glass. This will help ensure a good bond when the pane is re-sealed later. After the glass is clean, thoroughly wash both sides of it to remove any traces or smears.
Fit
Double glazing units that are sealed for replacement can be a cost-effective option to improve your home's comfort or reduce the energy bills. Modern replacement units are more energy efficient than previous models, and can be installed on the frame of your existing. They also offer security benefits, as they can be fitted with laminated and toughened safety glasses.
Accurate measurements are the key to a perfect fit. A UPVC frame has a very tiny tolerance. If you purchase a double-glazed unit a couple of millimeters more than the one you have already the frame will not seal properly. To avoid this problem, be sure to take measurements of the width and height of the window you have previously installed and then relay these measurements to the supplier.
A double-glazed unit's seal can be damaged due to a variety of reasons however the most common is the result of condensation between two panes of glass. This can cause a draught or calcium deposits to appear on the glass. This is usually a sign of an issue with the gas filler in the sealed unit or moisture has gotten into the frame.

Double-glazed units comprise two or more glass panels that are separated by spacer. The spacer bars contain desiccants which absorb moisture that may be present between the glass panes. When the windows are made or over the lifespan of your windows the seal can degrade, this is often caused by environmental factors like direct sunlight which can accelerate the shrinking of the seal, or harsh chemical cleaning products that can harm the seal.
The replacement double-glazed unit will be constructed according to the exact measurements of your window. After the new sealed unit has been placed into the frame, it is now time to seal the edges of your window. Use a silicone sealant that is suitable for Australia's climate and can endure thermal expansion and contraction.
When the silicone is applied to the side edge run your smoothing tool along it to press and squeeze the silicone onto the glass surfaces. it will eliminate any air bubbles, then fill gaps and make sure the seal is secure.
