After you have completed this, give the entire window a visual examination to ensure that there are no gaps or areas of misalignment that could impact its performance.

Once the gaskets are clean and the frame is clean, it's time to put in the sealed unit. To get the best results from this it's a good idea to remove the beads (the UPVC frame clips that hold the glass) and then measure them. This will ensure that the seal is constructed according to the correct dimensions and will not leave gaps around it.
When the beads are back in their place, you can insert the top bead and then move on to the next three. Be cautious not to touch the sealed units for a long time afterward as the silicone sealant needs time to set and become hard before you can use it again.

The most serious damage should be taken to an expert to repair.
Next, the spacer tubes are filled with desiccants in order to absorb any moisture trapped 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 as well as manual or automated dispensers of desiccant.
After the spacers have been filled and sealed, the glass is then sealed with a highly-performing silicone that is designed to withstand the harsh conditions of Australia's climate. This sealant creates an airtight seal that is both durable and flexible that can expand and contract without breaking. It's important to use the right thickness, as any gaps can impact the thermal performance. If you're not sure of the correct thickness to use, consult with a professional or manufacturer's guide.
