(1) Higher reflective capacity for solar heat radiation. Ordinary flat glass radiant heat reflectivity of 7% to 8%, heat-reflective glass up to 30% or so. (2) The heat-reflective glass coated with metal has the characteristic of unidirectional image transmission. Coated heat-reflective glass surface metal layer is very thin so that it has the characteristics of the mirror on the light side, and in the backlight side is as transparent as window glass. This strange property creates a variety of visual possibilities for people. When people stand in front of the coated glass curtain wall building, showing in front of the eyes is a continuous picture reflecting the surrounding scenery, but can not see the interior of the scene, the building's internal role as a cover and curtain, so the building can not be set up curtains. But when entering the interior, people see the interior decoration and the external scenery fused together to form an infinite open space. Because of these two valuable properties, heat-reflective glass offers excellent conditions for innovation in architectural design and flexibility in façade design.
