Hollow louver glass reminds the influence of glass thickness on visible light transmittance, which is the transmission ability of glass to visible light. As can be seen from the table below, with the increase of glass thickness, the visible light transmittance of white glass and ultra white glass decreases in varying degrees.

In the application of multi cavity insulating glass, due to the large number of glass sheets, special attention should be paid to the problem of visible light transmittance. For example, the visible light transmittance of three glass two cavity hollow glass composed of three 87% ordinary white glasses is only about 66%; With the same configuration of three 91% ultra white glasses, the visible light transmittance can be close to 76%, and the color difference is also large.
