WR305LE is a Low-Emissivity (Low-E) glass, which is used in the construction industry to reduce the thermal transmittance of windows. Low-E coatings are applied to the glass surfaces to reduce the solar radiation transmitted through the window, lower the energy consumption of the building, and consequently improve energy efficiency. The WR305LE glass reflects back about 48% of all absorbed solar energy while allowing a transmittance of 38%.

Low-E glass is used in window frames, doors, skylights, conservatories, and other glazing applications. In particular, the WR305LE glass is well suited for climates with hot summers and cold winters, as it helps to maintain a comfortable indoor environment all year round. On one hand, during winter, the Low-E glass helps to reduce heat loss, and on the other, during summer it helps to reduce solar heat gain. This improves the overall energy efficiency of the building and helps to reduce energy bills.

A low-emissivity coating is a thin film, usually metallic, applied to the glass surface. This coating is used to reduce the transmittance of solar radiation while still allowing the transmission of visible light. This coating is carefully balanced so that it allows the visible light to pass through while reflecting back the radiant energy in the form of infrared light. WR 305LE low-E glass uses a combination of silver and silver oxide coating, a process called dual silver coating, which gives it an optimal balance of visible light transmittance and low-E performance.

The working principle of WR305LE glass is very simple. When sunlight hits the glass, some of the energy is absorbed and some is reflected. The more solar energy that is absorbed, the more heat is transmitted into the interior of the building. With low-E glass, the coating helps to reduce the amount of solar energy that is transmitted through the window by reflecting it back out. This reduces the amount of heat that can enter the interior and thus improves the energy efficiency of the building.

In summary, WR305LE is a type of low-E glass that is designed to reduce the solar energy transmitted through windows and other glazing applications. The glass features a coating that reflects back 48% of all absorbed solar energy, while still allowing a transmittance of 38%. The coating helps to reduce heat gain during summer and heat loss during winter, which improves the energy efficiency of the building.
