Material Profile

As transparent thermal insulation materials have so far not been on the general market, there has been no other choice but to use vacuum glass or insert gas encapsulation technology for insulating transparent parts such as windows. Just by placing SUFA between sheets of glass, performance greater than that of triple glass can be obtained.
There is also a potential possibility that, in the future, SUFA itself can replace glass used for every window in the world as a highly insulating and lightweight glass.

SUFA's thermal insulation performance is about three times as high as that of the globally used insulators such as glass wool. This implies that a sheet of SUFA as thin as 1/3 of conventional thermal insulation materials can bring out equivalent performance. Even without the transparency feature, SUFA has a great advantage with regard to installation in residential space and transport vehicles in comparison to existing materials.

SUFA also holds a great advantage that cannot be found in aerogels manufactured by other companies. SUFA is outstanding in that it holds hydrophobicity (water repellency) in itself. As other companies' products do not have hydrophobicity, their thermal insulation performance declines significantly if they were to absorb water. While surface hydrophilization is performed to prevent this, perfect waterproofing is impossible as cracks cause water absorption leading to the decline of their performance.
With SUFA, degradation due to water is not an concern.
