All The Troubles Disappeared After Installing LOW-E Glass

Our architectural challenges were overcome with the installation of the revolutionary LOW-E glass, a transformative solution that has reshaped our approach to building design. Imagine a glass that can transform your living space. That's the power of LOW-E glass, or low-emissivity glass. Its surface coating, which reduces the glass's emissivity from 0.84 to below 0.15, unlocks a range of magical functions when installed in doors and windows. Let's explore these unique features and their benefits.

Uncover the distinctive traits of LOW-E glass, a material that sets new standards in energy efficiency and architectural design.

① It has a high infrared reflectivity and can directly reflect far-infrared thermal radiation. ② The surface emissivity is low, and the ability to absorb external energy is small. Thus, less heat energy is radiated out again. ③ The shading coefficient has a wide range, allowing for the control of solar energy transmission as needed to meet the requirements of different regions.

The LOW-E film layer has the characteristic of reflecting heat

The LOW-E film layer is coated with a silver layer. Silver can reflect more than 98% of the far-infrared thermal radiation, thereby directly reflecting heat, just like a mirror reflects light. The shading coefficient of LOW-E can range from 0.2 to 0.7, thereby allowing the direct solar radiation energy entering the room to be regulated as needed.

LOW-E glass coating process

There are two main types of coating: online coating and vacuum magnetron sputtering coating (also known as offline coating). Online coated glass is produced on the float glass production line. This type of glass has a single variety, poor thermal reflectivity, and low manufacturing cost. Its only advantage is that it can be hot-bent. There are various types of off-line coated glass, which have excellent heat reflection performance and obvious energy-saving characteristics. Its drawback is that it cannot be hot-bent.

The usage characteristics of LOW-E glass

Understanding the usage characteristics of LOW-E glass is crucial. For instance, LOW-E glass manufactured by the vacuum magnetron sputtering process is best suited for synthesizing insulating glass or laminated glass. Its emissivity E is significantly lower than 0.15, sometimes even below 0.01. On the other hand, LOW-E glass made through the online coating process can be used as a single piece, but its emissivity E is higher at 0.28. Strictly speaking, it's not considered LOW-E glass (scientifically, objects with an emissivity E≤0.15 are called low-emissivity objects).

Argon gas in LOW-E insulating glass

Argon is an inert gas, and its heat conductivity is worse than that of air. Therefore, when it is filled into insulating glass, the U value of insulating glass can be reduced, and its heat insulation performance can be increased. For LOW-E insulating glass, argon gas also protects the LOW-E film layer.

The UV attenuation function of LOW-E glass:

Compared with ordinary single-pane transparent glass, LOW-E glass can reduce ultraviolet rays by 25%. Compared with heat-reflective coated glass, LOW-E glass can reduce ultraviolet rays by 14%.

LOW-E glass has proven to be a game-changer in energy conservation, heat insulation, and UV protection, thanks to its unique low-radiation characteristics. Whether in residential, commercial, or green buildings, LOW-E glass significantly enhances energy utilization efficiency and reduces overall energy consumption. With its continuous technological advancements, LOW-E glass offers architects a wide range of options and plays a vital role in sustainable architecture. In the future, LOW-E glass is set to be a cornerstone of green buildings, steering the construction industry towards a more environmentally friendly and energy-efficient future.
