Today, more and more aluminum alloy doors and windows do not meet the energy saving standards. Why? Wocca doors and windows xiaowo takes you to know more about system doors and windows, door and window systems, and the differences between ordinary doors and windows! This issue focuses on "door and window system" and "system door and window".

"Door and window system": it is developed by the system for engineering design, manufacture and installation of building doors and windows that meet the set performance and quality requirements. It consists of materials, structures, door and window forms, technologies, performance is a whole set of elements.
Five core features of system doors and windows: systematic design, high insulation profiles, standard material formula, high quality hardware system and rigorous production process.
"System doors and windows": it is a perfect and organic combination of performance systems. Using the thinking mode of system integration, the doors and windows system developed based on the climate environment and functional requirements of different regions, all kinds of properties should be considered, such as water tightness, air tightness, wind pressure resistance, heat insulation, sound insulation, heat preservation, anti-theft, Operation feel, etc., and the design should be carried out according to the overall solution requirements and strict procedures, manufacture and installation, and finally form high-performance system doors and windows, with high reliability and cost-effective building doors and windows.

in the simplest words, there is "door and window system" and "system door and window". The door and window industry also combines system doors and windows with other common broken bridge aluminum doors and windows figuratively compared to "brand computer" and "assembled computer", this description should be better understood by everyone!
What are the real energy-saving system doors and windows?
The real energy-saving system doors and windows are not only made of insulated Bridge aluminum profiles or made of Low-E hollow glass energy-saving materials. It is a perfect combination of systems, and the comprehensive results of each link performance are indispensable.
Convection: the loss of heat is the circulating flow of hot and cold air through the gap between doors and windows, and the heat is exchanged through gaseous exchange, resulting in the loss of heat;
conduction: heat conduction is the heat transfer by the molecular movement of the materials used by doors and windows, which is transmitted to the other through one side of the material itself, resulting in heat loss;
radiation: radiation is mainly transmitted directly in the form of radiation, resulting in loss of energy consumption.
From the above three elements, we should pay attention to the following aspects for real energy-saving system doors and windows:
design and selection of profiles
if the heat insulation strips on the frame and fan material are not on the same side, after the hardware accessories are installed, the indoor and outdoor profiles are connected to each other through metal hardware accessories bypassing the heat insulation strips, thus making the heat transfer rapidly, affect the energy saving performance of doors and windows, etc.
Different profiles have different properties, mainly because different heat conduction systems determine the energy consumption of doors and windows. When you choose a material, it is very important to the design of profile section. System doors and windows give priority to cooperation with large factories in the selection of profiles, such as Xingfa, Jianmei, Huajian, Weiye and other output values, all of which are more than 2 billion, even more than 10 billion, quality, after-sales guaranteed brands all meet the standard of GB/T8478-2008 aluminum alloy doors and windows and the requirements of the current new standard of GB/T8478-2020. Through the quality requirements of the national standard, the profile section is strictly designed according to the overall solution.

glass selection
glass mainly consumes energy by heat radiation, and glass occupies almost the whole area of doors and windows, which is related to the functions of heat insulation, sound insulation, Collision Prevention, compression resistance and sunlight refraction of doors and windows. If the glass material is not good and the heat insulation is not good, poor sound insulation will generate unnecessary living costs, which will make life free of privacy and have no chance to be quiet.
The system doors and windows are made of superior glass original pieces and deep processing enterprises, including first-class brands such as South glass, Xinyi, North glass, Grant, Qibin, King Kong, etc., and produced glass products such as central control and tempering, the products of this kind of manufacturers can achieve the "high-speed rail" function, and the inert gas argon gas is filled in the middle, striving to make the heat insulation, sound insulation and noise reduction perfect. Therefore, when we choose the glass of building doors and windows, we must reasonably choose the glass to ensure the energy saving of the whole building.

selection of hardware accessories
"Hardware accessories are the heart of the whole door and window, not supporting corners, which can make the door and window play the greatest practicability and aesthetics". Hardware accessories play a very important role in energy-saving doors and windows. They are not only closely related to the air tightness, water tightness and wind pressure resistance of doors and windows, but also play a very important role in safety and other performance, try to choose high-quality brand hardware, including handle parts, transmission locking pieces, auxiliary parts and other combinations. System doors and windows are to optimize the linkage of various components, making doors and windows "live" and more humanized.

correct assembly and installation
the first points are the requirements of several groups of components of doors and windows. Reasonable selection of components is very important, and the correct combination of various components into a system is the perfect energy-saving doors and windows, so it has the strength, experienced door and window assembly plants are also crucial. If the quality of system doors and windows is good, and the performance of various combinations is excellent, once the chain is dropped on the installation, there will be potential safety hazards. Accidents of falling high-altitude doors and windows are common, among which there are reasons for improper installation.
System doors and windows strictly implement standardized operation procedures in production and assembly, and have independent supporting schemes in installation procedures to ensure a high-quality service experience for customers.
What is the purpose of energy saving of system doors and windows?
Generally, the design life of building houses is 70 years. It only takes us 6 years to recover the excess cost of building windows. System doors and windows make building energy-saving and efficiency-increasing for 64 years! Facts have proved that although the price of energy-saving system doors and windows is slightly higher, in the long run, energy-saving system doors and windows are the best choice to save money!
After talking about "system doors and windows" and "door and window system", Xiao wo will talk to you about the things of ordinary doors and windows in the next phase.
