The most common types of window and door glass

The most common types of window and door glass


As one of the important components of doors and windows, glass has the characteristics of light transmission, aesthetics, and heat insulation. Now there are more and more types of doors and windows, and different glass configurations are used in different scenarios.

Insulating glass is a composite structure composed of air layers. Through two or more layers of glass composite material, it forms an acoustic area, blocking the close contact between air and the outside world, effectively isolating the transmission of sound and achieving the function of noise reduction. The biggest advantage of insulating glass is energy saving and environmental protection.

Low-E glass, also known as low-emissivity glass, can play the role of thermal insulation. The principle is that the glass surface is coated with a multi-layer metal or other compound composed of film system products. The coating layer has the characteristics of high transmission of visible light and high reflection of medium and far infrared rays, reducing the emissivity of the glass from 0.84 to 0.1 or even lower, and reducing the radiation heat loss by nearly 90%. Low e glass is usually made into insulating glass with other substrates so that the insulating glass has the performance of sound insulation and heat insulation.


The energy consumption of modern buildings is mainly air conditioning and lighting, which account for 55% and 23% respectively. Glass is the thinnest and most thermally conductive material in building exterior walls.


Insulating glass has excellent thermal insulation performance because the desiccant in the aluminum frame keeps the air in the glass cavity dry for a long time through the gap above the frame.

Tempered glass is safety glass. Tempered glass is a kind of prestressed glass. To improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface, the glass withstands external forces first offset the surface stress, thereby increasing the load-bearing capacity and enhancing the glass itself to resist wind pressure, cold and heat, impact, etc.

Laminated glass is also a good material for door and window glass. Laminated glass uses two layers or multiple layers of safety glass bonded by film. Even if the glass is broken, the glass fragments will still stick to the film, to a greater extent of personal safety and higher safety.
