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。

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。
