High-Performance Resin Sashes
Since most heat escapes through the windows,we have paid particular attention to insulation performance of the windows.

Since "windows" have a large effect on the insulation properties of a house, we have adopted high-performance resin sashes. The glass-to-glass interstice is filled with "argon gas," which prevents heat loss and enables about a 73% reduction in heat loss compared to aluminum sashes. Our "special windows" boast an industry leading technology.
