There are some obvious differences between broken bridge aluminum doors and windows and aluminum alloy doors and windows in terms of performance, structure, and price.

1、 Structure

Aluminum alloy doors and windows: The overall material is aluminum alloy, and the metal has good thermal conductivity, which makes it easy for indoor and outdoor heat to be transferred through the doors and windows.

Broken bridge aluminum doors and windows: The broken bridge technology is adopted, which adds insulation strips in the middle of the aluminum alloy window frame to separate the window frame into two parts, inside and outside, effectively blocking the conduction of heat.

2、 Thermal insulation performance

Aluminum alloy doors and windows: Their thermal insulation performance is relatively poor, which can cause indoor temperatures to rise in summer and lead to heat loss in winter.

Broken bridge aluminum doors and windows: Due to the presence of insulation strips, they have good insulation performance and can effectively reduce the exchange of indoor and outdoor temperatures, saving energy consumption of air conditioning and heating.

For example, in hot summer, rooms with broken bridge aluminum doors and windows have significantly lower indoor temperatures, better air conditioning cooling effects, and lower energy consumption compared to rooms with aluminum alloy doors and windows.


3、 Sealing performance

Aluminum alloy doors and windows: The sealing effect is average, and there is a high risk of air and water leakage.

Broken bridge aluminum doors and windows: usually adopt multiple sealing designs, such as EPDM sealing strips, which have better sealing performance and can effectively block the intrusion of wind and rain.

4、 Price

Aluminum alloy doors and windows: The price is relatively low and cost-effective.

Broken bridge aluminum doors and windows: Due to their structural and performance advantages, the price is usually higher than that of aluminum alloy doors and windows.

5、 Durability

Aluminum alloy doors and windows: They have high strength, but long-term use may affect their appearance and performance due to oxidation and other reasons.

Broken bridge aluminum doors and windows: Adding insulation strips on the basis of aluminum alloy makes the overall structure more stable and durable.

For example, under the same usage environment and time, broken bridge aluminum doors and windows may maintain better appearance and performance, while aluminum alloy doors and windows may experience issues such as fading and deformation.

In summary, broken bridge aluminum doors and windows perform better in terms of insulation, sealing, and durability, but are more expensive; Aluminum alloy doors and windows are affordable and suitable for places with low performance requirements. When making a choice, it should be based on actual needs and budget.
