The visible light transmittance of low-E glass ranges from 0% to 95% in theory (6 mm white glass is difficult to achieve).

Product Details

Good optical properties of low-e glass:

The visible light transmittance of low-E glass ranges from 0% to 95% in theory (6 mm white glass is difficult to achieve). The visible light transmittance represents the indoor day lighting. Outdoor reflectance is about 10% - 30%. Outdoor reflectance is the visible light reflectance, which represents the intensity of reflection or the degree of dazzling. At present, China requires that the visible light reflectance of curtain walls should not exceed 30%.

Low-E glass has been widely used in developed countries because of the above characteristics. China is a relatively energy-deficient country, with a low per share of energy, and building energy consumption has accounted for about 27.5% of the total national energy consumption. Therefore, vigorous development of low-E glass production technology and promotion of its application fields will bring significant social and economic benefits.

Low-E glass in production, due to the particularity of material, after the cleaning machine, cleaning brush has higher requirements. Brushing must be a high-grade nylon brush, such as PA1010, PA612, etc. The diameter of the wire is 0.1-0.15mm. Because the brush silk has good softness, strong elasticity, acid and alkali resistance, temperature resistance, it can easily remove dust on the glass surface, and will not cause scratches on the surface.
