Ultra-clear glass

Common float glass looks green to certain degree. Especially when the glass is thickened or piled together, such phenomenon is more obvious. At present, the architectural designers have required higher optical requirements for the permeability of glass, thus the low-iron glasses occurred. Ultra-clear glass has very strong light transmittance. Its perfect transparency assures you to be able to obtain more perfect visual effect of natural color.
