1. Material Overview
Low-E glass, also known as Low-E glass, is the abbreviation of Low Emissivity in English. It is a film product with multiple layers of metal or other compounds coated on the surface of the glass.
Simply put, this kind of glass can both transmit light normally and block some heat energy. When heat energy (infrared) from the sun or HVAC hits low-E glass, it will be reflected back to the original space instead of being transmitted through the glass.
2. Material characteristics
a. Energy saving and environmental protection
Using Low-E glass to manufacture building doors and windows can greatly reduce the transfer of indoor heat energy to the outside due to radiation, achieving ideal energy-saving effects. At the same time, it can greatly reduce the fuel consumed for heating, thereby reducing the emission of harmful gases.
b. Thermal insulation
In winter, the indoor temperature is higher than the outdoor temperature, and low-E glass can transfer less indoor heat to the outside, thereby achieving a thermal insulation effect. Similarly, in summer, the indoor temperature is lower than the outdoor temperature, and the outdoor heat can be transferred to the indoor as little as possible, achieving a thermal insulation effect.
c. Excellent optical performance
The visible light transmittance of Low-E glass ranges from 0% to 95% in theory. The visible light transmittance represents the indoor lighting. The light transmittance of Low-E glass is much higher than that of ordinary white glass, and the visual effect is more transparent and the lighting is higher.
