Aluminum Alloy Casement Doors generally perform relatively well in different climates, but there are some specific factors to consider, especially environmental conditions such as temperature, humidity, and wind. Here are the specific performances of
aluminum alloy swing doors in different climates:
1.Cold climate
①Thermal expansion and contraction: Aluminum alloys will expand and contract to a certain extent when the temperature changes, but compared with wood or plastic materials, the expansion rate of aluminum alloys is smaller, so it is more stable. In cold environments, the dimensional changes of aluminum alloy door frames and door leaves will not significantly affect the opening and closing performance of the door.
②Sealing: The sealing strips of aluminum doors need to ensure a good seal to prevent cold air from entering the room. In cold climates, the insulation effect of aluminum doors can be enhanced by using double glazing (or Low-E
Glass) and high-quality sealing strips to prevent indoor heat loss.
2.Humid climate
①Corrosion resistance: Aluminum alloy itself has good corrosion resistance, especially anodized or coated aluminum alloy, which is more resistant to oxidation and corrosion in high humidity environments. Even if exposed to humidity for a long time, aluminum alloy doors are not easy to rust or corrode, and are usually more durable than steel doors.
②Moisture problem: Aluminum alloy door frames usually do not expand or deform in a humid environment like wooden doors. However, aluminum alloy doors need to ensure that the joints between the door frame and the door leaf are sufficiently sealed to prevent moisture from penetrating into the room.
3.Hot and dry climate
①Thermal expansion and contraction: Aluminum alloy will still expand slightly at high temperatures, but the overall change is small. Therefore, aluminum alloy swing doors can still maintain good shape and function in high temperature environments.
②Weather resistance: Aluminum alloy has strong weather resistance and is not easily affected by ultraviolet rays, so it can be exposed to the sun for a long time without fading or aging. Compared with wooden doors or PVC doors, aluminum alloy doors will not have problems with cracking or brittleness.
③Thermal conductivity: Aluminum has a high thermal conductivity, which may cause the door frame to be hotter in summer and increase the burden on indoor air conditioning. Using insulated aluminum alloy door frames (such as thermally insulated aluminum alloy) can effectively solve this problem and reduce indoor temperature fluctuations.
4.Windy climate
①Stability: Aluminum alloy itself has high strength and stability, and can withstand strong winds, preventing the door frame from being deformed or damaged by strong winds. The design of aluminum alloy doors can be reinforced according to wind requirements to ensure stability in windy weather.
②Sealing: Strong winds may increase the air leakage in the door gap, causing indoor temperature changes. To solve this problem, it is very important to use high-quality sealing strips and a well-designed sealing system. Aluminum alloy swing doors equipped with high-quality sealing strips can effectively isolate strong winds from the outside.
Aluminum alloy casement doors usually perform well in all kinds of climate conditions, especially in terms of corrosion resistance, stability and long-term use. If you choose technologies such as anodizing and thermal insulation, the performance of aluminum alloy doors can be guaranteed in any climate. However, for the insulation needs in cold climates and the sealing in strong winds, you still need to pay extra attention to the appropriate design and material selection.
