INSULATION WINDOW HAVING A DOUBLE LAYERED GLASS STRUCTURE

摘要

PURPOSE: An insulation window having a double layered glass structure is provided to efficiently shield inflow of sunlight energy into the indoor and sunlight hotwires by blocking near-infrared rays and far-infrared rays and have excellent insulation effect in the summer and the winter season. CONSTITUTION: An insulation window having a double layered glass structure includes an outer window(110), an inner window(210), a near-infrared ray absorption layer(120), a far-infrared ray reflection layer(220). The inner window is installed to be faced with the outer window. The near-infrared ray absorption layer is coated on the inner surface of the outer window which is faced to the inner window. The near-infrared ray absorption layer absorbs the near-infrared rays which is applied from external light and penetrated through the outer window. The far-infrared ray reflection layer is coated in the inner surface of the inner window which is faced to the near-infrared ray absorption layer. The far-infrared ray reflection layer reflects the far-infrared rays which are penetrated not to be absorbed by the near-infrared ray absorption layer.
