玻璃贴面行业中的辐射率(EMISSIVITY)和降氏眩光(GLARE REDUCTION)什么是?

EMISSIVITY(E) Emissivity is a measure of surfaces ability to absorb or reflect far-infrared radiation.The lower the emissivity the higher the far - infrared reflection. Infrared radiation is  that which is sensed by the body as heat. The lower the emissivity rating,the better the insulating qualities of the glazing system.

辐射率（E）：辐射率是指贴膜玻璃吸收或反射太阳能量总和和总太阳能的百分比。

GLARE REDUCTION( GR):Glare reduction is the percentage of reduction in visible light transmission through a glazing system without film to that with film.

降氏眩光：眩光是指阳光中产生的刺眼强光，贴膜玻璃能大大降低这种强光。
