The commonly used insulating glass for thermally-insulated aluminum doors and windows are mainly the following types:

1. Float insulating glass: It is composed of two or more pieces of float glass combined by a spacer frame and sealant, and has certain heat insulation and sound insulation performance;

2. Tempered insulating glass: Its two or more pieces of glass are tempered, with higher strength and better safety, and also have good heat insulation and sound insulation performance;

3. Coated insulating glass: By coating a special film on the surface of the glass, such as Low-E film (low-radiation coating), the heat insulation performance can be further improved, and the transmission of infrared and ultraviolet rays can be effectively blocked, which has better energy-saving effect;

4. Low-E insulating glass: It has excellent thermal performance and can greatly reduce the transmission of indoor heat energy to the outside, thereby achieving an ideal energy-saving effect. At the same time, it has a high transmittance of visible light in the sun, low reflectivity, and good optical performance;

5. Laminated insulating glass: It is composed of one or more layers of organic polymer intermediate film sandwiched between two or more pieces of glass. Even if the glass is broken, the fragments will stick to the film, which can effectively prevent the fragments from being damaged and penetrating and falling. It is highly safe and has excellent seismic intrusion resistance. Its sound insulation performance is also excellent;

6. Multi-layer insulating glass: For example, the common three-layer insulating glass, which is formed by three glass plates to form two sealed air layers (or rare gas layers), may have better heat insulation and sound insulation performance than double-layer insulating glass.

When choosing insulating glass, it is necessary to consider the requirements of heat insulation, sound insulation, thermal insulation, safety, and other aspects, as well as factors such as budget. At the same time, it is necessary to pay attention to choosing products produced by regular manufacturers to ensure quality and performance. The performance of aluminum alloy doors and windows depends largely on the type of insulating glass selected, and appropriate choices should be made according to actual needs.
