To solve the contradiction of the function of lighting, sound insulation, winter protection, heat prevention and energy-saving, we developed this product. We seal in one layer of insulated movable shutter, use electromagnetic induction to control the shutter. It combines the function of heat prevention, heat preservation, lighting, and get good effect of visible light soot rate, solar radiant energy transmit rate and absorb rate, ultraviolet radiation transmit rate, sheltering coefficient.

With excellent design, simple scheme, competitive price, it realized the energy-saving target which other glass( like vacuum glass, coated glass, )can not. It aroused influential reform of doors and windows, and even to wall partition. It aroused stirring effect both in the domestic and overseas market just when it comes into the market.
