Once the beads are removed allow the sealed unit to drop slightly out of the frame and with an assistant, hold it in position while you precisely measure the height, width and the thickness. This is crucial as it will determine the size of the wedge gasket that must be cut to accommodate the double glazed unit.
Checking
Double glazing units or sealed units, as they are often called, can break down over time. This is usually due to an opening in the seal, which allows moisture and condensation into the space between the panes.

Once you've completed this make sure you give the window an extensive visual inspection to ensure that there aren't any gaps and that it is not misaligned.
It may be necessary to apply a small amount of sealant around the perimeter edge of the frame in order to prevent it from moving in future.

This is a standard practice for a warm edge sealed unit. Thermoseal Group stocks a range of desiccants, as well as manual and automated dispensers of desiccant.
After the spacers are filled, the glass and frame are sealed using a high-performance silicon, specifically designed to withstand Australia's tough climate. This sealant forms a barrier that's both strong and flexible capable of expanding and expand without becoming brittle or breaking. It's important to use the correct thickness, since any gaps could impact thermal performance. If you're not sure about the right thickness to use seek advice from a professional or manufacturer's guide.
