After the spacers have been filled with glass, it is sealed with a high performance silicone that's designed to withstand Australia's harsh climate. This sealant forms a barrier that is both strong and flexible, able to expand and contract without becoming fragile or breaking. It's crucial to select the right thickness, as any gaps could affect the thermal performance. Ask a professional for advice or refer to the manufacturer's manual in case you're not sure about the thickness you should use.

The final step is to apply a secondary sealant, which is typically polyisobutylene (PIB) or similar products. This is applied along the outside edges of frames to form a secondary seal. It will ward off moisture and prevent air infiltration, thereby increasing energy efficiency.
