What is Low Iron Float Tempered Glass?

Low iron float glass also named Ultra-clear glass. It is made by matured technical operation norm. It looks just like colorless crystal with higher transmittance.
Compare to common float glass, it is with outstanding characteristics of the high solar lights transmittance, the low reflectance, the low iron, the high mechanical strength and the high flatness, it is the ideal encapsulation material for thin solar modules and thermal collectors.
Low iron float tempered glass is low iron float glass that

has been processed through a tempering oven to increase its strength to resist impact, mechanical loads and thermal stress breakage. It is approximately four times stronger than annealed glass of the same thickness and configuration. When it is broken, tempered glass fractures into small fragments that reduce the probability of serious injury as compared to annealed glass.
What is the Spectral Data of 3.2mm Low Iron Float Tempered glass?



It is of higher energy transmittance about 91%
It is expensive compare to clear float glass
It is highly smooth without patterned which more suitable for thin film solar modules and thermal collectors.

Where to use it?
· Front cover glass of of thin film photovoltaic technology, including amorphous silicon (aSi), cadmium telluride (CdTe) and copper indium diselenide (CIS).
· Front cover glass of thermal collectors.
