With the changes of the times, the materials of doors and windows are constantly improving, from ancient paper windows to today's aluminum alloy doors and windows. At present, more and more people give up traditional glass windows and choose broken bridge aluminum doors and windows. Why? What are the benefits of broken bridge aluminum doors and windows?
For broken bridge aluminum alloys, hardware is very important, and the quality of the upper pulley even plays a decisive role in the service life of aluminum alloy balcony windows.
In addition, the lock on the lower part of the aluminum alloy of the broken bridge, the smoothness of the pulley, the length and quality of the top, etc., all need to be paid attention to.
Finally, pay attention to the aluminum profiles used in the upper and lower parts of the outer frame. If the thickness of the aluminum profile is not enough, its load-bearing capacity cannot meet the daily needs. Even if there is no typhoon, it is easy to deform. The following Baydee uPVC Profiles editor Let everyone know.
1. Heat insulation: The thermal conductivity of heat-insulating broken bridge aluminum alloy profiles is 1.8~3.5W/㎡·k, which is much lower than that of ordinary aluminum alloy profiles, which are 140~170W/㎡·k. The thermal conductivity of insulating glass structure is 2.0~3.59W/㎡·k, which is much lower than 6.69~6.84W/㎡·k of ordinary aluminum alloy profiles, which effectively reduces the heat conduction through doors and windows.
2. Anti-condensation: The temperature of the inner surface of the profile with thermal insulation strip is close to the indoor temperature, which reduces the possibility of condensation of indoor moisture on the surface of the profile due to oversaturation.
3. Energy saving: In winter, the profiles have built-in thermal insulation strips, which can reduce the heat loss through the profiles by 1/3; when the air conditioner is turned on in summer, the profiles with thermal insulation strips can reduce the energy loss more.
4. Environmental protection: The application of door and window insulation system reduces energy consumption and reduces environmental radiation generated by air conditioning and heating.
5. Noise reduction: The hollow glass structure with different thicknesses and the heat-insulating broken bridge aluminum profile cavity structure can effectively reduce the resonance effect of sound waves, prevent sound transmission, and reduce noise by more than 30dB.
6. Diverse: After anodizing, powder spraying, and fluorocarbon spraying surface treatment, aluminum profiles of different colors can be produced; after rolling and combination, the doors and windows can show the effect of indoor and outdoor two-color windows.
1. Look at the quality of the material
The quality of the profile can be observed from the surface of the broken bridge aluminum profile. Good broken bridge aluminum profiles have a glossy surface, natural surface spray treatment, and smooth feel; poor broken bridge aluminum doors and windows have a rough surface, no luster, and appear unnatural.
After a period of time, poor broken bridge aluminum doors and windows will change color or fade, and the color is not full.
2. Look at the section structure of the profile
A good broken bridge aluminum door and window profile section has an accurate geometric angle, the profile will not be bent and twisted, and the angle is correct. Also, the thickness of the section is sufficient. For example, custom-made 60-type broken bridge aluminum doors and windows, 60 means that the thickness of the profile is 6cm, and the 6cm is full of broken bridge aluminum materials, and the threading ratio is small; and the second broken bridge aluminum alloy doors and windows will use virtual support 60 profiles, with wear The strip supports this thickness, and there is less aluminum.
3. Look at the profile insulation strip
It depends on whether the insulation strips are imported or domestic. Domestic insulation strips are mostly made of PVC plastic, and imported insulation strips are mostly made of polyamide, that is, nylon insulation strips. High-quality broken bridge aluminum doors and windows adopt imported thermal insulation strips, which have good high temperature resistance and low temperature resistance performance, low thermal conductivity, and can achieve the effects of heat insulation, environmental protection and energy saving, and can save 20%-30% of energy.
It adopts the soft combination of the inner and outer frames of thermal insulation profiles, and the three-sealing form of the frame with rubber strips, which is tightly closed, has excellent airtight and watertight performance, and has excellent thermal insulation performance.
The broken bridge aluminum profile can realize the three-layer sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully achieve equal pressure balance of gas and water, significantly improve the water tightness and air tightness of doors and windows, and achieve the effect of clean and bright windows.
Invisible screens, which can be installed inside and outside, can prevent mosquitoes and flies.
The broken bridge aluminum anti-theft and anti-loosening device ensures the stability and safety of the window in use.
Its structure has been carefully designed with tight seams to effectively isolate noise.
Broken bridge aluminum windproof sand, wind pressure resistance. The inner frame straight material adopts hollow design, which has strong resistance to wind pressure deformation and good anti-vibration effect.
Broken bridge aluminum has high strength, unchanged shape and maintenance-free.
Broken bridge aluminum in a variety of colors, very decorative.
The aluminum opening forms of the broken bridge include flat opening, inclination type, upper suspension type, push-pull type, flat opening and inclination and compound type, etc. The appropriate form can be selected according to the needs.
Broken bridge aluminum doors and windows will not produce harmful materials in the production process, all materials can be recycled and reused, and are green building materials and environmentally friendly products.
If you feel that it is troublesome to buy aluminum alloy balcony windows with broken bridges, you can remember two simple points: one is to look at the brand, and the other is to look at the quality.
