Major damage should be referred to an expert for repair.
The spacer tubes will be filled with desiccants to take in any moisture that could have accumulated between the two panes during production or over time. This is a common practice for a warm edge door seal repairs. Thermoseal Group stocks a range of desiccants, as well as manual and automatic desiccant dispensers.
After the spacers are filled with glass, it is sealed with a high performance silicone designed to withstand the harsh conditions of Australia's climate. The sealant creates an airtight barrier that's both durable and flexible, and can expand and contract without breaking. It's crucial to select the right thickness, as any gaps could impact the thermal performance. Ask a professional for advice or refer to the manufacturer's manual in case you're not sure about the thickness to use.
The final step is to add secondary sealant. This is usually polyisobutylene or another similar material. It is applied to the edges of frames to form an additional seal. It is able to repel moisture and stop air infiltration, thereby increasing energy efficiency.
