Installation
If the window has been installed correctly the new unit will fit firmly in place and will fit comfortably within the frame. If the new glazed unit isn't of the same thickness as the old one, then you might need to modify the existing "packers" (usually red or blue slips of plastic) within the frame to ensure it is properly placed. If you're not sure what to do, consult your installer or the instructions of the manufacturer for advice.

Once the beads have been removed and the sealed unit is free of them, allow it to slide a bit out of the frame. With the help of a person to hold it in place while you take measurements of its size, height and width. This is important as it will determine the size of the wedge gasket that you will need to cut for the new double glazed sealed unit.
Checking
Double glazing units or sealed units as they are usually called, may break down over time. It is usually due to a leak in the seal, which allows moisture and condensation into the space between the panes.

Talk to a professional or consult the guidelines provided by the manufacturer to ensure that you order the correct size.
With the help of a friend holding the new unit, gently place it in the frame. It is crucial to do this in a secure location since the glass is fragile and may fall out and break. After the sealed unit is secure within the frame, re-attach any packers that are at the bottom of the frame, and then put the glazing beads back in their original position. Once you have done this give the whole window a visual examination to make sure there are no gaps or areas of misalignment that could compromise its performance.
You may also need to apply a bit of sealant to the outer edge of the frame to prevent it from moving in future. It is recommended to check the thickness of the glass unit.

If you are replacing a sealed unit, the first step is clean the frame. Use a paintbrush from the past (4 inches is the ideal size) to scrub the frame, getting rid of dust that has built up 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 out. It is also important to make notes of the length you need for your new seals as it will help in cutting them to the required size.
Once the gaskets are cleaned and the frame cleaned up it's time for the sealed unit. It's a good idea take off the beads (the UPVC frames clips that hold the glasses) and then measure them. This will ensure that the seal is constructed to the right size and will not leave any gaps around it.
After the beads are reinserted, you can start with the top one and work your way down to the other. You should be careful not to touch your sealed units for a long time afterward as the silicone sealant will need some time to set and harden before you can use it again.

Major damage should be referred to a professional for repair.
Next, the tubes for the spacer are filled with desiccants to adsorb any moisture that may be trapped in-between the two panes of glass during the process of manufacturing or after time. This is a common practice for a warm edge sealed unit. Thermoseal Group stocks a range of desiccants and manual or automated dispensers for desiccant.
After the spacers have been filled and sealed, the glass is then sealed with a highly-performing silicone designed to withstand Australia's harsh environment. This sealant creates an airtight barrier that's both flexible and durable and can expand and contract without breaking. It is crucial to choose the right thickness, as any gaps can affect thermal performance. Talk to a professional or consult the manufacturer's manual for more information on the right thickness for your.
The last step is to apply an additional sealant, usually polyisobutylene (PIB) or an equivalent product. It is applied to the outside edges of frames to create an additional seal. It can repel moisture and stop air infiltration, thus increasing the efficiency of energy.
