Comparing broken-bridge aluminum windows and ordinary aluminum windows
Analyze the differences between broken-bridge aluminum doors and ordinary aluminum doors so that we can make a choice.
In order to clearly present the difference between broken bridge aluminium and ordinary aluminium alloy doors and windows, I will compare and analyse a number of key aspects such as structural design, heat preservation, sound insulation, strength and durability, strength and durability on, price and cost, etc., so that you have a comprehensive understanding of the differences between the two.
Structural design
Aluminium alloy: a material with a broad concept, it is the most widely used non-ferrous structural material in industry. Its main component is aluminium, and add some alloying elements (such as copper, magnesium, silicon, manganese, etc.) to enhance its performance. It usually has an integral metal structure profile. Ordinary aluminium doors and windows of the profile is integral, there is no partition inside the profile, the thermal conductivity of the metal can be directly through the whole profile
Broken Bridge Aluminium: It is an upgraded product of aluminium alloy with a unique structural design, in which a heat insulating strip is embedded in the middle of the aluminium alloy profile, which ‘breaks’ the aluminium alloy profile from the middle and forms a structure similar to a ‘bridge’ being blocked. The heat-insulating strip is generally made of PA66 nylon (polyamide 66), which has good heat-insulating properties. This is where the name ‘bridge’ comes from. This design radically alters the heat conduction path of the profile.
Thermal insulation performance
Aluminium alloy: The metal properties of ordinary aluminium alloy make it conduct heat quickly. In winter, the heat inside the room will be transferred to the outside quickly through the profile, resulting in a lower temperature inside the room; in summer, the high temperature outside will be transferred to the inside through the profile, increasing the energy consumption of air-conditioning. Therefore, its thermal insulation effect is relatively poor.
Broken Bridge Aluminium: As there is a heat insulating strip in the middle of the broken bridge aluminium, it greatly reduces the heat conduction. Insulation strip is like a ‘barrier’, can effectively prevent the transfer of heat. Tested, the use of broken bridge aluminium window frame room, compared with the use of ordinary aluminium alloy window frame room, the entry of outdoor heat in the summer can be reduced by about two thirds, the indoor heat distribution in winter can be reduced by about 40% -50%. It is more in line with the requirement of energy saving and heat preservation of modern buildings.
Sound insulation performance
Aluminium alloy: ordinary aluminium alloy doors and windows of the profile sealing is relatively weak, coupled with the vibration conduction properties of the metal itself, the outside world’s noise is easy to be transmitted into the room through the profile and gaps
Broken bridge aluminium: Broken bridge aluminium doors and windows also have more advantages. Broken bridge aluminium doors and windows in the structural design pay more attention to sealing, with multi-layer insulating glass, can effectively block the airborne sound and solid sound transmission, generally can reduce the noise by more than 30 decibels, for the street, the airport near the noise pollution is more serious area, the advantage is particularly obvious.
Strength and durability on
Aluminium alloy: ordinary aluminium alloy doors and windows of the thin profile, long-term use may appear deformation, loosening and other problems, the service life is relatively short, generally in 10-15 years, while the service life of the broken bridge aluminium doors and windows can be up to 20-30 years.
Broken-bridge aluminium: the thickness of the profile of broken-bridge aluminium doors and windows is usually thicker than ordinary aluminium alloy, coupled with the unique structural design, the overall wind pressure resistance and stability is stronger, and can adapt to high-rise residential and other high strength requirements of doors and windows of the environment.
Sealing performance
Aluminium alloy: The sealing performance of aluminium alloy doors and windows mainly depends on the sealing strip of the doors and windows. However, due to its relatively simple structure, the sealing effect is limited. In heavy rain and windy weather, there is a risk of rain leakage or air infiltration.
Broken Bridge Aluminium: Broken Bridge Aluminium doors and windows are designed with multiple sealing strips, together with high-quality sealing materials, effectively preventing the entry of rain, air and dust. To adapt to different climatic conditions and ensure room temperature.
Cost and price
Aluminium alloy: ordinary aluminium alloy doors and windows are relatively low in price, suitable for scenes with limited budget and low requirements for heat and sound insulation, such as temporary buildings and warehouses.
Broken-bridge aluminium: Broken-bridge aluminium doors and windows are more suitable for family houses and high-grade flats that have higher requirements for living comfort and energy saving. The price of broken-bridge aluminium windows and doors is usually 50%-100% higher than ordinary aluminium alloy windows and doors due to the higher cost of materials (heat-insulating strips, thicker profiles, etc.) and more complicated processing technology.
conclusion
With the above comparison, you can choose the right windows and doors according to your needs and budget. If you still want to know more about the difference between these two kinds of windows and doors in terms of installation, maintenance, etc., or have other specific questions, please feel free to let me know.Rutao will help you make the wisest choice.
