Thermal insulation-Low-e glass(low-Emissivity glass)is one of the coated glass products with the vacuum sputtering process coats glass surfaces with several layers of different materials on the glass surface,compared with ordinary glass and traditional coated glass for building,this product offers the high transparency,low reflectivity,good thermal insulating and energy-saving properties required of modern architectural glass and green building design。
Benefits
Approaches the natural color of glass.
HHG low-e glass can apply for single glazing,don't worry coated oxidize when exposed to air,
Highly transparent to visible light(wavelength 380nm-780nm);will not produce significant glare problems caused by high reflectance of visible light.
Allows most sunlight in the visible range to enter without altering its natural color.Provides excellent natural illumination and saves energy by reducing the need for artificial lighting.
Relatively high reflectance of infrared
radiation(wavelength780nm-3,000nm).In particular,reflects nearly all long-wave infrared(wavelength greater than 3,000nm).Blocks the entrance of large amounts of heat,and leaves interior comfortably cool in summer and warm in winter.
Properly reduce UV transmittance and avoid fade of furniture and textile.
scratch resistance,easy removed,see below pictures
