Differences between Broken Bridge Aluminum and Aluminum Alloy？

Broken Bridge Aluminum VS  Aluminum Alloy

Structural Design

• Aluminum Alloy: It's a broad - concept material and is the most widely used non - ferrous metal structural material in industry. Its main component is aluminum, and some alloying elements (such as copper, magnesium, silicon, manganese, etc.) are added to enhance its performance. It usually has an integral metal - structured profile.

• Broken Bridge Aluminum: It's an upgraded product of aluminum alloy. It has a unique structural design. A thermal - insulation strip is inserted in the middle of the aluminum alloy profile, which "breaks" the aluminum alloy profile in the middle and forms a shape like a "bridge", hence the name "Broken Bridge Aluminum". The thermal - insulation strip is generally made of PA66 nylon (Polyamide 66) material, which has good thermal - insulation properties.

Performance Characteristics

Thermal - insulation Performance

• Aluminum Alloy: The thermal conductivity of ordinary aluminum alloy is relatively high, and heat can be easily conducted through the profile. For example, in summer, the outdoor heat will quickly be conducted into the room through the aluminum alloy window frame, and in winter, the indoor heat will also dissipate relatively quickly. So its thermal - insulation effect is relatively poor.

• Broken Bridge Aluminum: Due to the presence of the thermal - insulation strip in the middle of the broken - bridge aluminum, the heat conduction is greatly reduced. The thermal - insulation strip acts like a "barrier" and can effectively prevent the transfer of heat. According to tests, a room with broken - bridge aluminum window frames can have about two - thirds less outdoor heat coming in during summer and can reduce indoor heat dissipation by about 40% - 50% during winter compared to a room with ordinary aluminum alloy window frames.

Sound - insulation Performance

• Aluminum Alloy: Ordinary aluminum alloy doors and windows generally have a limited sound - insulation effect because their overall structure has a limited ability to block sound. Sound is mainly transmitted through air and solid (window frame), and aluminum alloy itself has a weak ability to reflect and absorb sound.

• Broken Bridge Aluminum: Broken - bridge aluminum doors and windows perform better in terms of sound - insulation. On the one hand, the broken - bridge structure reduces the path of sound conduction through the window frame; on the other hand, some high - quality broken - bridge aluminum doors and windows are also equipped with multi - layered insulating glass, further improving the sound - insulation effect. For example, double - layered insulating - glass broken - bridge aluminum doors and windows can effectively reduce noise by about 30 - 40 decibels, creating a quiet indoor environment.

Sealing Performance

• Aluminum Alloy: The sealing performance of aluminum alloy doors and windows mainly depends on the sealing strips of the doors and windows. However, due to its relatively simple structure, the sealing effect is limited. In strong - wind or heavy - rain weather, there may be cases of rain leakage or air infiltration.

• Broken Bridge Aluminum: Broken - bridge aluminum doors and windows usually adopt a multi - channel sealing design, combined with high - quality sealing strips, which can effectively prevent rain, air and dust from entering. This multi - channel sealing system can better adapt to different climatic conditions and ensure the comfort of the indoor environment.

 Cost and Price

• Aluminum Alloy: It has a relatively low cost, the production process is relatively simple, and the price is also relatively affordable. In some places where the performance requirements for doors and windows are not very high, such as some simple warehouses, ancillary buildings of ordinary residences, etc., using aluminum alloy doors and windows can meet the basic usage requirements and reduce costs at the same time.

• Broken Bridge Aluminum: Due to its special broken - bridge structure, high - quality thermal - insulation strips, and advanced sealing and sound - insulation technologies, the production cost is relatively high. Correspondingly, the price is also more expensive than ordinary aluminum alloy doors and windows. However, in the long run, the energy - saving effect of broken - bridge aluminum doors and windows can save energy costs to a certain extent, such as air - conditioning and heating costs.

Application Scenarios

• Aluminum Alloy: It's suitable for places where the requirements for thermal - insulation, sound - insulation and sealing performance of doors and windows are not particularly high. For example, some temporary buildings, industrial plants, balconies of ordinary residences (non - enclosed balconies with low performance requirements).

• Broken Bridge Aluminum: It's more suitable for buildings with high requirements for indoor environmental comfort, such as high - end residences, office buildings, hospitals, schools, etc., which require good thermal - insulation and sound - insulation effects. Especially in the northern heating areas in winter and the southern areas where air - conditioners are frequently used in summer, it can effectively reduce energy consumption.
