Broken bridge aluminum doors and windows are mainly made of heat-insulating broken bridge aluminum profiles and insulating glass, which have the functions of energy saving, sound insulation, noise prevention, dust prevention, waterproof and so on.
advantage:
1. Good thermal insulation;
2. There is a drainage outlet designed to ensure smooth drainage and good water tightness;
3. The three-way sealing structure separates the water vapor chamber, realizes the balance of water pressure and air pressure, and prevents condensation and frost;
4. Metal material, heat insulation strip, high temperature resistance, non combustion, fire prevention function;
5. Broken bridge aluminum doors and windows do not produce harmful materials in the production process, and the materials can be recycled, which belongs to green building materials;
6. High strength, not easy to deformation and corrosion, almost no maintenance.
Disadvantages:
1. To achieve the thermal insulation performance of broken bridge aluminum doors and windows, PA66 thermal insulation strip is required, but its price is high, so the price of broken bridge aluminum doors and windows is also high.
2. In addition, because PVC spacer is cheaper, some illegal businesses may cut corners, so they need to pay more attention when purchasing.

1. Thermal conductivity
The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, as well as automobile cylinder heads and radiators.
2. Machinability
The machinability of aluminum profile is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in various states after the production of these alloys, the machining characteristics change greatly, which requires special machine tools or technologies.
3. Recyclability
Aluminum has high recyclability, and the characteristics of recycled aluminum are almost the same as that of primary aluminum.
4. Corrosion resistance
The density of aluminum profile is only 2.7g/cm3, about 1 / 3 of that of steel, copper or brass (7.83g/cm3 and 8.93g/cm3 respectively). Aluminum shows excellent corrosion resistance under most environmental conditions, including air, water (or brine), petrochemical and many chemical systems.
5. Conductivity
Aluminum profile is often selected because of its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice that of copper.
