What to Look For in a Double Glazing Sealed Unit Replacement
Double glazing or sealed units, as they are known will break down over time. This is usually evident as a draft within the home.
The lifting and placing of the new unit is a delicate process that requires precision and care. The process of 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 start to fail. This typically manifests as an air leak in the unit or a weakening of the airtight seal. The gas (normally Argon, an inert gas) may leak from the panes over time due to shrinkage. Seal degradation may also be by environmental factors such as exposure to direct sunlight, or the use of powerful chemical cleaning products that can cause damage to the glass and weaken seals.
When a seal fails, it can create a snoring sensation in a home and it is not unusual to notice an improvement in the energy efficiency of a home because of it. This is why it's a good idea to conduct a regular visual inspection of your double-glazed.

It is important to accurately measure the window before replacing it with a double-glazed sealed unit. The UPVC frames they are placed in are extremely rigid and if a unit is too large it will not fit. To do this accurately it is essential to remove the beads and measure them. This will ensure that the new sealed unit has the correct size. You can buy replacement UPVC frame beads online from suppliers who provide a variety of warm edge options such as aluminium and steel.
Remove

Begin by opening any vent or casement windows in the frame to reach the edge of the existing glass unit. Then, place your calipers on the frame, and clip them against the existing unit on both sides to measure the thickness. This will give you the size of the new sealed unit and enable you to order it in accordance with the measurements.
Then, carefully cut the strip of adhesive that keeps the glass in place using a utility knife. After you've removed it, gently pry the glass away from the frame with a putty knife or shovel. Remember that the glass is extremely brittle and may break if you force it. Be careful not to scratch or harm the frame or sealant.
Clean and prepare the frame to be sealed with double-glazed. If you're installing a brand new sealed unit, make sure you choose the right silicone caulk that will endure the harsh Australian weather without becoming brittle or flaky.

Clean
Over time, the inside of double-glazed windows could become foggy or opaque. This is a sign that seals are failing, and that the window needs to be replaced.

After removal of the old unit, the frame can then be cleaned and ready for a new double-glazed window that is sealed. Based on the design of the window, it could be necessary to paint or prime the window prior to applying the sealant. It is essential that any varnish or paint is allowed to completely dry before the sealant is applied.
If the existing window was secured using beads, these will need to be removed before a replacement unit can be fitted. This can be done with an screwdriver or chisel. Place the blade on the edge of the bead and gently remove it from the frame. To avoid damaging the window frame, make several shallow cuts instead of one deep cut. Once you have removed the bead frame carefully lift it away from the remaining glass pane and place it in a safe place to dry.
Shave any remaining sealant off the bottom of your glass using an instrument or knife. This will ensure a strong seal when the panes are sealed. After the glass is clean, thoroughly wash both sides of it to eliminate any traces or smears.
Fit

Modern replacement units are more energy efficient than previous models, and can be installed on the existing frame. They also offer security advantages, as they can be fitted with glasses that are laminated and toughened.
The key to a good fit is accurate measurements. A UPVC frame has a very tiny tolerance. If you choose a double-glazed unit a few millimeters bigger than the one you have already the frame will not seal properly. To avoid this problem ensure that you measure the width and height of the window you have previously installed and relay these dimensions to the supplier.
The seal of a double-glazed unit can be damaged due to a variety of reasons, but the most common is the result of condensation between two glass panes. This can cause draught or unsightly calcium deposits on the glass. This is usually a sign of a problem with the gas filler in the sealed unit or that moisture has made its way into the frame.

The spacer bars contain desiccants that absorb any moisture that may be present between the glass panes. The seal material may degrade in the course of manufacturing or over the life of your windows. This is typically caused by environmental factors, such as direct sunlight, which can cause shrinkage of the seal, or by strong chemical cleaners that will damage the seal.
