Why Low Iron flaot glass is popular in the building industry?

1.Low rate of spontaneous breakage after tempered

Due to low iron glass raw materials usually contain less NiS and other impurities´╝îComparing to annealed glass,low iron has a more uniform composition,its impurities less.So  reduce the  risk greatly after low iron glass tempered.

2. Color consistency

Since the iron content in the raw material is only 1/10 or less of the annealed glass, the ultra white glass absorbs less of the green band in the visible light than the ordinary glass, ensuring the consistency of the glass color.

3..Hihgly Visible light transmittance and excellent  permeability 

More than 91.5% in visible light transmittance,

4,Ultraviolet transmittance is low

Comparing to annealed glass ,Low iron glass has a lower absorption in ultraviolet band.used in anti-ultraviolet places.Such as museums and other areas, which can  reduce the through of ultraviolet  light effectively ´╝îreduce  the fade  of the showcase , especially for protecting Cultural relics.
Ultra-white glass less heat than ordinary float glass, can reduce the heat loss, it is more suitable for making double silver Low-E insulating glass used in the glass curtain wall.
