How Does Aeroseal Work?

The Aeroseal process seals leaky ducts from the inside by injecting sealant into the system under positive air pressure.

The air pressure differential allows the sealant to find the leaks in the system – even the ones you would have trouble finding or accessing if you were trying to seal the system manually.

The sealant then accumulates in the gaps, eventually plugging them with a strong, flexible material. But we’d rather show you than tell you!
