Low iron glass vs Clear float glass

Ultra-clear glass is a kind of ultra-transparent low-iron glass, also known as low-iron glass and high-transparent glass, the light transmittance can reach more than 91.5%.

Low Iron or Ultra Clear Glass delivers maximum clarity and color neutrality – clear to the edge. Without the green tint of standard float glass.

low Iron Glass. the light transmittance can reach more than 91.5%

Clear Float Glass, the light transmittance is between 82% – 87%

Difference between low iron glass and clear float glass.

1. lower glass self explosion rate.

As we know, the Nis inside glass will cause glass spontaneous breakage.

The Nickle mainly exist in the glass raw materials, and the float glass and low iron glass raw materials source are quite different, the low iron glass with the much stricter requirement, the raw materials are purer, which will decrease the tempered glass spontaneous breakage ratio, which can even compete with the heat soaked tempered glass breakage ratio, 3‰ is believed to be a reasonable rate.

2. Much pure color.

Ultra Clear Glass delivers maximum clarity and color neutrality – clear to the edge, Without the green tint of standard float glass.

The normal clear glass color is slightly green, especially a thick glass panel,15mm,19mm, the green color is more obvious, it’s caused by the iron content of the raw materials.

3. Higher light transmittance & solar coefficient.

The low iron glass allows much higher light transmittance and allows more solar energy transmitted to the glass, that’s the reason, greenhouse, solar panels, photovoltaic panels, and museum glass prefer low iron glass to get more solar energy and more clear appearance.

4. Lower UV transmittance.

The low iron glass allows less UV to penetrate the glass and protect the interior furniture and fabrics.

The low iron glass data is as below.

5. Different Processing Production Difficulty

The production difficulty of low iron glass is much higher than clear glass because of strict raw materials and production lines, as well as glass production technology. that’s the reason only a few float glass manufacturers can produce low iron glass.

The manufacturers include PPG, Pilkington Glass, AGC, China CSG, XYG, SYP, Jinjing.

The superior visual performance of ultra-clear glass will greatly improve the function and decorative effect of processed glass products. Therefore,ultra-clear glass has a wide range of applications and broad market prospects.

It’s widely used in high-end buildings, high-end glass processing, and solar photovoltaic curtain walls, as well as high-end glass furniture, decorative glass, imitation crystal products, lamp glass, precision electronics (copiers, scanners), special buildings, etc.
