Hollow shutter glass
Angle adjustment is possible to freely and control the light and line-of-sight.
The insulation resistance of the multi-layer glass, it was plus the heat shield by the blind which is sandwiched between the glass. By the blind angle adjustment, it will be able to further up the insulation effect while controlling the light and the line of sight.
