With the continuous development of society,broken bridge aluminum alloy windows and doors are more and more widely used in decoration.broken bridge aluminum alloy windows and doors are aluminum doors and windows made of thermally insulated broken bridge aluminum profiles and insulating glass, which have outstanding sound insulation effects, Dustproof and waterproof, etc., So, are there any disadvantages for such a good performance of broken aluminum doors and windows?

Advantages ofbroken bridge aluminum alloy windows and doors:

1. Reduce heat conduction: The use of insulated bridge-broken aluminum alloy profiles and hollow glass structure effectively reduce the heat conduction through doors and windows.

2. Prevent condensation: The temperature of the inner surface of the profile with heat insulation strips is close to the indoor temperature, reducing the possibility of indoor moisture condensation on the surface of the profile due to oversaturation.

3.Energy saving: In winter, window frames with thermal insulation strips can reduce 1/3 of the heat lost through the window frame; in summer, if it is air-conditioned, the window frames with thermal insulation strips can Reduce energy loss more.

4.Protect the environment: Through the application of heat insulation system, energy consumption can be reduced, and the environmental radiation caused by air conditioning and heating can be reduced at the same time.

5.Good for health: The heat exchange between the human body and the environment depends on the temperature of the indoor air, the air flow speed and the temperature of the outdoor air. The most comfortable environment has been achieved by adjusting the indoor temperature of doors and windows so that it is not lower than 12～13℃.

6.Noise reduction: The use of hollow glass structures with different thicknesses and a cavity structure of thermally insulated aluminum bridges can effectively reduce the resonance effect of sound waves, prevent sound transmission, and reduce noise by more than 30dB.

7.Colorful colors: aluminum profiles of different colors can be produced after surface treatment with anodizing, powder spraying, and fluorocarbon spraying. After rolling and combining, the insulated aluminum alloy doors and windows can produce indoor and outdoor two-color windows with different colors.

Disadvantages of broken aluminum doors and windows: complex production and expensive.

It can be seen from the article that there are still many advantages of broken aluminum doors and windows, including reducing heat conduction, preventing condensation, reducing noise, etc., reducing energy loss can also protect the environment and benefit physical and mental health. Of course, everything is There are two sides. Although it has so many advantages, it also has its disadvantages. It is not easy to make, and the combination of advantages and disadvantages also indirectly leads to its price is not cheap.

As for broken bridge aluminum windows and doors or aluminum alloy windows and doors, people have different opinions.

Well, today I would like to analyze for you that there are four main differences between broken bridge aluminum windows and doors and aluminum alloy windows and doors. The details are as follows

1. There are some differences in thermal insulation.
   Aluminum alloy windows and doors are not insulated, especially in summer, the surface of aluminum alloy will be very hot under the baking of the sun, and aluminum is a metal material, and its thermal conductivity is generally recognized as good, so the spread of this kind of heat will increase the temperature in the house.
   However, the broken bridge aluminum windows and doors in the interlayer between the windows and doors into the thermal insulation material, sandwiched with this material can completely block the heat transfer of indoor and outdoor air temperature.
2. There are some differences in the effect of sound insulation.
   Aluminum alloy windows and doors may have a sound insulation effect in the society at that time, because the harm of noise at that time is not as much as it is now, but with the development of the times, ordinary windows and doors can no longer achieve the sound insulation effect.
   Broken bridge aluminum windows and doors in the interlayer of the windows and doors mixed with a layer of sound insulation material, the material has a small hole invisible to the naked eye, it is this kind of hole has a sound insulation effect.
3. There are some differences in hardness.
   In the process of using aluminum alloy windows and doors, if they are hit by the outside world, it is easy to change the original state, resulting in the deformation of windows and doors, thus affecting the normal use of windows and doors.
   The broken bridge aluminum windows and doors adopt the internationally prescribed profiles, and the single-layer wall thickness of the doors and windows is at least 1.4 mm. The inner cavity wall design of the broken bridge aluminum windows and doors adopts a multi-level ladder design style, which can maximize the hardness of the windows and doors.
4. There are some differences in sealing performance.
   The traditional aluminum alloy doors and windows will not be tightly closed after a few years of use, whether it is the door or the window.
   Broken bridge aluminum windows and doors completely solve this problem, the inner cavity of broken bridge aluminum windows and doors adopts 5-channel sealing design, while ordinary aluminum alloy only has the most basic layer design.

Therefore, the better the sealing performance of the broken bridge aluminum windows and doors.

Aluminum alloy windows and doors, refers to the use of aluminum alloy extruded profiles as frames, mullions, fans for the production of windows and doors called aluminum alloy windows and doors referred to as aluminum windows and doors.
Aluminum alloy windows and doors include aluminum alloy as stress members (members that bear and transfer dead weight and load) and wood-plastic composite windows and doors, referred to as aluminum-wood composite windows and doors, aluminum-plastic composite windows and doors.
The quality of aluminum alloy windows and doors can be roughly judged from the selection of raw materials (aluminum profiles), aluminum surface treatment and internal processing quality, and the price of aluminum alloy windows and doors.

Aluminum alloy windows and doors are now more commonly used, with many advantages and disadvantages.
The fireproof property of aluminum alloy windows and doors is better than rigid ones, no need for paint and maintenance, grow new or not old, avoid the tiredness and trouble of your maintenance, comprehensive cost economy, relatively long service life.
Disadvantages: poor toughness, cold tone, poor heat preservation effect, poor sound insulation, poor air tightness, air leakage and water leakage, and the surface is easy to change color if it is not handled well.
The grade is lower, and the ordinary home decoration is used more.
The characteristics of aluminum alloy windows and doors tools are as follows:

1. Light weight and high strength.
2. Good sealing performance.
3. Fixed groove.
4. Beautiful shape.
   5, strong corrosion resistance: aluminum alloy oxide layer does not fade, does not fall off, does not need to be painted, easy to maintain, no need to repair.
