What are the advantages of aluminum frame double glazed windows compared to single-glazed windows in terms of thermal insulation, heat insulation, and sound insulation?

1. Advantages of thermal insulation
Principle: There is a certain gap between the two pieces of glass in double-glazed glass to form an "air layer". Air is a good thermal insulation material. When the temperature difference between indoor and outdoor is large, the air layer becomes an obstacle to the conduction of indoor and outdoor temperatures, preventing the transfer of indoor heat to the outdoors. At the same time, aluminum frame double glazed windows also have good thermal insulation properties, further enhancing the thermal insulation effect of the windows.
Effect: The heat loss on the building surface can be effectively reduced by preheating the air between the double-glazed curtain walls. In addition, double-glazed glass can reduce heat conduction by more than 50%, significantly improving the thermal insulation performance of windows.

2. Thermal insulation advantages
Principle: The air layer (sometimes filled with inert gas such as argon) between the double-glazed glass can effectively prevent heat transfer through conduction, thereby reducing indoor and outdoor heat exchange. This structure allows the double-glazed glass to block outdoor heat from entering the room and reduce the indoor temperature in the summer; in winter, it can reduce indoor heat loss and keep the indoor temperature stable.
Effect: The heat transfer coefficient of double-glazed windows is only 29% to 56% of single-glazed windows, and heat loss can be reduced by about 70%. This means that under the same external environment, indoor temperature fluctuations using aluminum-frame double-glazed windows are smaller and the living comfort is higher.

3. Sound insulation advantages
Principle: The air layer of double-glazed glass can absorb sound waves and effectively reduce external noise from entering the room. At the same time, the unique design of the aluminum alloy frame can also reduce noise transmission. This structure makes double-glazed windows at soundproofing.
Effect: Double-glazed windows can reduce noise by 30 to 45 decibels or even more than single-glazed windows. In noisy urban environments, the use of double-glazed windows can significantly reduce interference from outside noise and provide a quieter living or working environment.
