what is low e glass
Low-E glass, full name is low-emissivity coated glass (Low-E Glass), is a glass with a film composed of multiple layers of metal or other compounds on the surface of the glass. This film has the characteristics of high transmittance of visible light and high reflection of mid- and far-infrared rays. Compared with ordinary glass and traditional architectural coated glass, it has good heat insulation effect and good light transmittance.
low e glass types
The surface coating of Low-E glass is mainly composed of metals such as silver, copper, tin or other compounds. These materials can reduce the emissivity of the glass surface, thereby reducing heat transfer.

low e Features
Excellent thermal insulation performance:
The surface of Low-E glass is coated with multiple layers of metal or other compound films, which have the characteristics of high transmittance of visible light and high reflection of mid- and far-infrared rays. This allows it to effectively maintain indoor heat in winter and block external heat from entering in summer, thus achieving the effect of warm in winter and cool in summer.
Good light transmittance:
The visible light transmittance of Low-E glass can range from 0% to 95%, depending on the design of the film layer. The transmittance of high-transmittance Low-E glass is above 70%, which can ensure sufficient natural light indoors.
Environmental protection and energy saving:
The use of Low-E glass can significantly reduce energy consumption and carbon emissions caused by heating and air conditioning. It can effectively reduce indoor and outdoor heat exchange, thereby reducing dependence on air conditioning and heating equipment, and reducing the operating costs of homes and businesses.
Protect the indoor environment:
Low-E glass can also block most ultraviolet rays, protect indoor furniture and decorations from ultraviolet damage, and extend their service life. In addition, its low thermal conductivity can reduce condensation on the window surface, maintain home hygiene, and prevent mold and bacteria from growing.
Various types:
Low-E glass can be classified according to the number of functional layers and light transmittance. Common types include single silver, double silver and triple silver Low-E coated glass, which have different numbers of film layers and functions. The light transmittance is divided into high transmittance (light transmittance above 70%), medium transmittance (light transmittance 50%-70%) and low transmittance (light transmittance below 50%).
low e glass benefits
Insulation:
The surface of Low-E glass is coated with a low-radiation film, which can effectively reflect infrared rays and reduce heat loss. In winter, it can prevent indoor heat loss and maintain indoor temperature; in summer, it can block external heat from entering and keep the room cool, thereby reducing the energy consumption of air conditioning and heating equipment
Energy saving and environmental protection:
By reducing the use of air conditioning and heating equipment, Low-E glass can significantly reduce energy consumption and carbon emissions, meet the requirements of green buildings, and contribute to sustainable development
Ultraviolet protection:
Low-E glass can effectively block most ultraviolet rays, protect indoor furniture and decorations from ultraviolet damage, and extend their service life
Good lighting:
Low-E glass has a high visible light transmittance, usually between 0%-95%, which ensures good indoor lighting effects
Reducing condensation:
The low thermal conductivity of Low-E glass can reduce the temperature difference on the window surface, thereby reducing the condensation of water vapor on the glass surface, keeping the window dry, and preventing the growth of mold and bacteria
low e glass producing process
Online high-temperature pyrolysis deposition method
Completed during the cooling process of float glass. Liquid metal or metal powder is directly sprayed onto the surface of hot glass. As the glass cools, the metal film becomes part of the glass. The advantages of this method are low cost, heat bending and tempering, no need to use in a hollow state, and long-term storage. Its thermal performance is poor. Unless the film layer is very thick, its “u” value is only half of that of sputtered Low-E coated glass. If the film thickness is increased to improve thermal performance, the transparency will deteriorate.
Offline vacuum magnetic sputtering method
Depending on the different glass transmission positions, there are horizontal sputtering and vertical sputtering. The Low-E glass produced by the offline method is rich in variety, excellent in heat reflection performance, and obvious in energy-saving characteristics. According to different climatic characteristics, high, medium and low transmittance products can be produced, and the colors include silver gray, light gray, light blue and colorless transparent. This kind of glass cannot be hot-bent, and the silver oxide film layer is very fragile. It must be made into hollow glass for use, and it is not suitable for long-distance transportation before it is made into a hollow product.
low e glass applications
In various buildings, especially in residential, office buildings, shopping malls and other places. It can not only improve the overall quality and energy-saving effect of the house, but also achieve green and environmentally friendly operation. In northern regions, due to the higher requirements for insulation in winter, Low-E glass is more widely used.

FAQ
What is the function of low e glass?
Low-e glass is like a mirror, mainly used to reflect infrared heat radiation in the light. If the far infrared heat radiation in the light hits the glass, Lowe glass will reflect this heat radiation out. In winter, since the heat comes from indoors, when the heat radiation hits the window glass, it is reflected back into the room, so that the home can achieve a warm winter and cool summer effect.
low e glass vs normal glass
Low-E glass is coated with low-radiation metal coating, which reflects infrared rays, has strong heat insulation, is warm in winter and cool in summer, saves 30%-50% energy, reduces electricity bills, and blocks 90% of ultraviolet rays to protect furniture; ordinary glass has no coating, poor heat insulation, and weak ultraviolet blocking.
Low-E costs 10%-15% higher, but it pays for itself in the long run with energy savings, and is suitable for extreme climates or energy-saving buildings;
Ordinary glass is economical but has low efficiency, and is suitable for mild climates or short-term projects.
Low-E reduces condensation, maintenance requires gentle cleaning, and ordinary glass has high durability. The choice is based on climate, budget, aesthetics and energy-saving needs. Choose Low-E for high efficiency, and choose ordinary glass for budget priority.
is low e glass worth it
The price of insulating glass varies depending on factors such as type, size, and material. Generally speaking, the price is between 100-300 yuan per square meter. However, there are also high-end or special specifications of insulating glass that will cost more, which may reach hundreds or even thousands of yuan per square meter. The specific price still needs to be determined according to your actual needs and choices.
disadvantages of low-e glass
Higher price:
The production process is complex and requires the use of special equipment and materials. The price of Low-E glass is relatively high, which may increase the decoration cost
Poor processing performance:
Compared with ordinary glass, Low-E glass has poor processing performance and cannot be hot-bent, which may limit its application in some designs
Low light transmittance:
Compared with ordinary glass, Low-E glass has a lower light transmittance, which may affect spaces with higher lighting requirements
Will Low-E glass affect lighting?
Low-E glass has a high transmittance to visible light, so it will not significantly affect lighting. In fact, Low-E glass can provide good indoor lighting while reducing heat transfer, achieving energy saving and a comfortable indoor environment.
Which side of the glass is the Low-E film layer on?
The Low-E film layer is usually located on the inner side of the glass, that is, the second or third side of the insulating glass. The purpose of this is to protect the film layer from the external environment, extend its service life, and ensure its thermal insulation performance.
How to judge whether the glass is equipped with Low-E
Observation method: In outdoor sunlight, if the surface of the glass presents a light blue or gray, it may be Low-E glass.
Reflection test: Use an infrared lamp or flashlight to illuminate the glass. If the reflected light is strong, it may be Low-E glass.
Professional test: Using professional Low-E test instruments, such as spectroreflectometers, you can accurately measure the emissivity of the glass to determine whether it is Low-E glass.
