1. High visible light transmittance and good permeability: In addition to all the processing properties of high-quality float glass, ultra-white glass has superior optical properties and high visible light transmittance, generally greater than 91. %, the ultra-white glass plated with double silver Low-E is used on the curtain wall to increase the permeability and effectively reduce the lighting cost. 
2. The ultra-white glass after tempering has a lower self-explosion rate: since the ultra-white glass raw material contains less impurities, the control of the raw material melting process is more fine, which makes the ultra-white glass have a more uniform composition than ordinary glass, thereby greatly reducing the The chance of self-explosion after tempering. It is used on the curtain wall and has a safety advantage over ordinary glass. 
3. The color uniformity is better, more beautiful: because the iron content in the raw material is much lower than that of ordinary glass, the ultra-white glass absorbs less on the green band in the visible light than the ordinary glass, ensuring the consistency of the color of the glass and avoiding the cause. The aesthetics caused by the color difference of the glass curtain wall. 
4. Less heat absorption: Ultra-white glass absorbs less heat than ordinary float glass, which can reduce heat loss, so it is more suitable for making double-silver Low-E insulating glass on glass curtain wall.
