Insulated glass does not significantly absorb visible light, but instead absorbs near-infrared light that generates a large amount of heat, which can reduce the temperature to around 3℃-6℃. Because of its characteristics such as heat insulation, energy saving and environmental protection, it is widely used in commercial buildings, hotels, hotels and other fields.
