After the beads are removed, allow the sealed unit to fall slightly from the frame and with an assistant, hold it in position while you measure it accurately length, width and the thickness. This information is essential because it will determine the size wedge gasket you will need to cut for your brand new double glazed sealed units.

Checking

Double glazing units or sealed units as they are commonly called and can fail over time. This is usually due to a breach in the seal which allows moisture and condensation to get into the space between the panes. This can affect the way the window can keep out cold air, heat produced by the heating system inside the home, and solar heat inside.

Get advice from a professional or follow the guide provided by the manufacturer to ensure that you purchase the right size.

With the help of a person who holds the new unit gently place it in the frame. This must be done in a safe area as the glass may break if it falls out. After the sealed unit is secured to the frame reattach any packers on the bottom of frame and then reinstall the glazing beads back into their original positions. After you have completed this, give the entire window a thorough inspection to ensure there aren't any gaps or misalignments that could affect its performance.

You may also need to apply a bit of sealant around the perimeter edge of the frame to prevent it from moving in future. Checking the thickness of the unit is a good thing to do. This is essential since double-glazed units come in various thicknesses and if you choose the wrong one, it can impact the u-value your home's insulation.

Sealing

Double glazing can increase the thermal efficiency of your home and improve acoustics. However, over time, the seals in the glass can get worn out, leading to misty windows and a decrease in performance. In these cases, replacement is essential.

Once the frame is clean it's a good idea to give the seals that are new a thorough clean too. It is easiest to remove gaskets for the wedge from the friction joint by placing your fingers on the edge of the gasket and pulling it out. You should also take a note of the length that you need for your new seals as it will be useful in cutting them to the required size.

Once the gaskets are cleaned and the frame is clean, it's time for the sealed unit. To get the best results when doing this it's a good idea to remove the beads (the UPVC frame clips that are used to hold the glass) and then take measurements of these. This will ensure that the seal is constructed to the correct size and there are no gaps around it.

After the beads have been reinserted, you can start with the top one and move down to the others. After sealing the units, you must not touch them for a few hours because the silicone sealant must set and harden. I typically leave it for about 6 hours before handling but this will differ based on your silicone sealant's setting time.

Finishing

It's also a good opportunity to look over any damages and make small repairs by using wood filler or sanding if required. For more serious damage it is recommended to seek out a professional.

The spacer tubes are then be filled with desiccants in order to take in any moisture that could have been trapped between the two panes in the process of manufacturing or over time. This is a typical procedure for units with warm edges. Thermoseal Group stocks a range of desiccants as well as manual or automated dispensers of desiccant.

After the spacers have been filled, the glass and frame are sealed with a high-performance silicone, specifically designed to withstand Australia's harsh climate. This sealant forms an airtight barrier that is both flexible and durable, and can expand and contract without breaking. It is important to use the right thickness since any gaps could affect thermal performance. If you're not sure about the proper thickness, consult with a professional or manufacturer's guide.

The final step involves adding secondary sealant. This is usually polyisobutylene or another similar material. This is applied along the outside edges of frames to create an additional seal. It is able to repel moisture and stop air infiltration, thereby increasing the efficiency of the energy.
