●The biggest function of Taiwan's energy-saving film Low R series glass products is to reduce the penetration of heat radiation, so that the indoor temperature is not easy to rise, thereby reducing the burden of air-conditioning and achieving the purpose of energy saving and carbon reduction.
●However, Low R glass is not suitable for cold regions such as the United States, Japan, Europe, South Korea, and Russia. These countries require Low E (Low Emissivity), which is low re-emissivity glass. The surface of this glass is plated with metal and the metal faces indoors. The purpose is Reflect the secondary radiation in the room to achieve the effect of heat preservation, which can reduce the burden of the heater in the cold zone and achieve the purpose of energy saving and carbon reduction.
●Therefore, different glasses must be properly applied to achieve the maximum effect, otherwise it will have the opposite effect. However, if you use double silver or triple silver or more glass in tropical areas, because of the refractive index of different metals, light interference technology can radiate heat outward. Refraction can also achieve heat insulation.
