insulated glass

insulated glass Characteristics Optics prosperity :According to the features of the raw glass used, generally, transmittance rate for visible lights is about 70% to 80%, reflective rate is about 13% to 42%. Thermal prosperity: insulating glass can effectively decrease the U-value, if inert gases filled between the glasses, the effect will be much better. Sound insulating prosperity: general insulating glass can decrease the noise by 30 decibels. If filled with inert gases, the insulating glass can decrease the noise by 15 decibels more. Prosperity of anti-frosted: According the regulation of China, the dew point for the insulating glass should be below - 40. Generally, the dew point of insulating glass is 15 lower than the common glass. Specifications: The norm thickness of air layer is :6mm ,9mm,12mm ,15mm. The thickness of glass is 3、4、5、6、8、10、12mm 1. Flat insulating glass Maximum size: 3500*2500mm Minimum size: 300*300mm Thickness: 1460mm 2. Bent insulating glass Maximum size: 3500*2500mm Minimum size: 300*300mm Thickness: 6 80mm Standard of the products: GB 11944-2002,
