Once you've completed this, give the window a thorough visual inspection to ensure there are no gaps and that it isn't misaligned.

The easiest way to do this is to lever out the gaskets on the Wedge by placing your fingers on the edge, and then pulling it out until you reach the point that it overlaps with the friction joint. Make a note of how long you need your new seals. This will assist when cutting them.
After the gaskets have been cleaned and the frame cleaned up it's time to install the sealed unit. To get the best results from this, it's recommended to prise out the beads (the UPVC frame clips that hold the glass) and then measure these.

After the beads are in place you can insert the first bead and proceed to the other three. After sealing the units, you must not touch them for a few hours because the silicone sealant must harden and set.

After the spacers have been filled with the spacers, the glass and frame are sealed using a high-performance silicon, specifically designed to withstand Australia's harsh climate. This sealant creates an airtight seal that is both durable and flexible, and can expand and contract without breaking. It is essential to choose the correct thickness as any gaps could affect thermal performance. Consult a professional or the manual of the manufacturer in case you're not sure about the thickness to use.
