You should also take an outline of the length that you need to make your new seals, as it will be helpful in cutting them to the required size.

The installation of the sealed unit is straightforward once the frame and gaskets have been cleaned.

This is a common practice for a warm edge seal. Thermoseal Group stocks desiccants as well as manual and automated desiccant dispensing equipment.

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 creates an airtight barrier that is both durable and flexible and can expand and contract without breaking. It is crucial to choose the right thickness since any gaps could affect thermal performance. Consult a professional or the manufacturer's guide for more information on the thickness you should use.

The final step is to add secondary sealant, typically polyisobutylene (PIB) or an equivalent product. It is applied to the outside edges of frames to form a secondary seal. It can repel moisture and stop air infiltration, thereby increasing the efficiency of the energy.
