Why does the 100 series aluminum curtain wall profile help buildings achieve high efficiency and energy saving?

In the process of modern buildings pursuing high efficiency and energy saving, the 100 series aluminum curtain wall profile stands out and becomes a key element in achieving the goal of building energy saving. Its significant contribution to energy saving during the use stage of buildings is largely due to its excellent thermal insulation performance and its exquisite combination with high-efficiency thermal insulation materials.
Heat transfer is mainly carried out through three methods: conduction, convection and radiation. In the building envelope, the transfer of heat will lead to the loss of indoor energy or the entry of excessive heat, thereby increasing the energy consumption of the building. The 100 series aluminum curtain wall profile shows unique design and material advantages in dealing with these three heat transfer methods.

In terms of heat conduction, the 100 series aluminum curtain wall profile uses a special aluminum alloy. Aluminum alloy itself has a lower thermal conductivity than traditional metal materials, which means that the speed of heat conduction inside the profile is relatively slow. In addition, in the structural design of the profile, engineers have carefully created a multi-cavity structure. These cavities are like tiny "insulation barriers", further hindering the heat conduction path. When outdoor heat tries to conduct indoors through the curtain wall profile, the multi-cavity structure will block the heat conduction process many times, causing the heat to be continuously weakened in the cavity, greatly reducing the efficiency of heat conduction into the room through the profile.

For heat convection, the 100 series aluminum curtain wall profile is installed with tight sealing strips and high-efficiency insulation materials to form a nearly closed space. Indoor and outdoor air is difficult to conduct large-scale convection exchange under such a sealed structure. Even when the outdoor temperature changes drastically, due to the good sealing, the air cannot enter and exit freely, and the heat convection phenomenon is effectively suppressed. For example, in the hot summer, the outdoor hot air cannot easily convect with the indoor cold air through the curtain wall, and the indoor air conditioning cooling effect can be maintained for a long time, thereby reducing the operating frequency and energy consumption of the air conditioner.

In terms of heat radiation, the surface of the 100 series aluminum curtain wall profile is usually specially treated. This treatment forms a coating with a certain reflectivity on the profile surface, which can reflect some of the heat radiation from the sun. When sunlight hits the curtain wall, the coating works to reduce the amount of heat absorbed by the profile and transferred to the interior in the form of radiation. This is like putting a coat on the building that can "reflect sunlight", effectively blocking the heat brought by solar radiation.

More importantly, the 100 series aluminum curtain wall profiles complement high-efficiency thermal insulation materials. Common high-efficiency thermal insulation materials, such as polyurethane foam and rock wool, have extremely low thermal conductivity. When these thermal insulation materials are used in combination with the 100 series aluminum curtain wall profiles, the thermal insulation effect is further enhanced. The thermal insulation material is filled in the cavity of the profile or the inner layer of the curtain wall, which is like adding a solid "insulation line" to the building. When heat passes through the curtain wall, it needs to pass through the barrier of the profile first, and then pass through the thermal insulation material. Under multiple obstacles, the amount of heat transfer is greatly reduced. Whether it is to keep the room warm in the cold winter or to resist the high temperature outside in the hot summer, this combination can ensure that the indoor temperature is relatively stable, greatly reducing the energy consumed by the building to regulate the temperature.
