"Hardware accessories are the heart of doors and windows, not supporting roles." 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.
System doors and windows: refers to doors and windows that have undergone three processes: system research and development, customization and standard installation. It is a perfect organic combination of performance systems, which needs to consider water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, A series of important functions such as operating hand feeling should also consider the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose and seals, which are indispensable and finally form high-performance system doors and windows.

01. Five performance
first, let's know the five performance levels of doors and windows:
(1) wind pressure resistance: it refers to the performance that the outer doors and windows are not damaged under the action of wind pressure; For example, cracking, profile damage, glass damage, bonding failure are not easy to occur, the opening obstacles of loose hardware are divided into 9 levels, and the system doors and windows reach level 6 on average (the standard of wangmei doors and windows 98 series reaches level 9 International highest level)

(2) air tightness: a simple point is that the ability of the outer doors and windows to prevent air penetration under the normal closed state is divided into 8 levels in total, and the system doors and windows reach 6 levels on average, import system doors and windows can reach the highest level. (Standard configuration of wangmei doors and windows 98 series reaches Level 8, the highest international level)
(3) watertightness: the ability of doors and windows to prevent rainwater infiltration when it is windy and rainy under normal closed conditions is divided into 6 levels, and the system doors and windows reach level 4 on average. (Standard configuration of wangmei doors and windows 98 series reaches Level 6, the highest international level)

(4) thermal insulation performance: that is, the k value mentioned in the professional terms of doors and windows. The system doors and windows are not lower than the level 3 standard. (the standard configuration of wangmei doors and windows 98 series reaches level 7, and the K value reaches 1.2)
(5) sound insulation performance: Also called sound insulation and noise reduction, refers to the ability to weaken the sound transmission from the sound source to the listener, which is divided into 6 levels in total, and the system doors and windows are not lower than the level 3 standard. (The standard configuration of wangmei doors and windows 98 series reaches Level 4, and the sound insulation of glass configuration increases accordingly)
02. What are the benefits

1. Good thermal insulation performance: The Windows really have excellent functions such as sound insulation, heat insulation and heat preservation, which can greatly save the cost of refrigeration and heating, and the energy-saving cost of several years is enough to make up for the previous investment.
Example: no matter in the south and north, whether it is water heating, electric heating or air conditioning heating, the monthly cost is about 600-1000 yuan. According to this standard, the cost of a family in heating reason is roughly 2000-3000 yuan. If the energy-saving standard of 40% for energy-saving doors and windows is used, ordinary families can save 800-1200 yuan in a winter.
2. Good waterproof function: use the pressure balance principle to design a structural drainage system, set a drainage outlet and smooth drainage.
3. Anti-theft and anti-loosening devices: equipped with unique multi-locking points to ensure the stability and safety of windows during use.

4. Anti-frost and condensation: System door & window profile can realize three sealing structures of doors and windows, significantly improve the watertightness and air tightness of doors and windows, and achieve the effect of bright windows.
5. Noise-proof and sound-proof: well-designed structure, tight joints, test results, sound-proof 35-45dB, which can ensure that the room is not disturbed by noise and the room is warm.
6. The high strength of doors and windows is unchanged: the system doors and windows have high tensile strength, shear resistance and deformation resistance, and are firm, durable and maintained. According to the research of system doors and windows abroad, "the average actual service life of system windows is 15 to 30 years, while the actual service life of ordinary doors and windows is 5 to 15 years", this shows the huge gap between the system window and the ordinary window.

7. Strong wind pressure resistance and good seismic effect: it can be used in high-rise buildings and residential buildings, and can design large-area window type with large lighting area. The air tightness of the window is better than that of any window, which can ensure that there is no dust in the sand area.
8. Many opening methods, comfortable and durable: suitable for public buildings, residential quarters and municipal projects. The preferred hardware accessories are durable, and the operating handle is designed with humanization, which is beautiful and comfortable, and easy to open and flexible. After inspection, it slides easily. Mature and perfect door and window processing technology, high precision program control processing center for production, stable and guaranteed quality.

03. Selection of system doors and windows

1. Profiles
first of all, choose profiles of different materials whose performance is different, mainly because the different heat-conduction coefficient determines the energy consumption of doors and windows. Wood is one of the profiles with the lowest thermal conductivity.

2. Glass
the loss of energy is mainly caused by convection, conduction and radiation. Glass is mainly heat radiation energy loss, so when we choose the glass of building doors and windows, we must reasonably choose glass to ensure the energy saving of the whole building. Because of the rise of passive houses, the demand and requirements for energy-saving doors and windows are constantly increasing, which also greatly promotes the development of doors and windows industry. Glass needs low-e Glass or vacuum glass, and the profiles must basically be wood or plastic, with air tightness not lower than Grade 8, water tightness not lower than Grade 6, wind pressure resistance not lower than Grade 9, etc. (For more professional knowledge, see: professional science popularization is coming!

3. Hardware accessories
"Hardware accessories are the heart of doors and windows, not supporting roles." 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.
Reasonable configuration and design of hardware accessories for doors and windows of energy-saving system on the configuration of hardware accessories for energy-saving doors and windows, select a well-locked multi-point locking system to ensure that under the action of wind pressure, fan and frame deformation are synchronized, effectively ensure the reasonable cooperation of sealing materials, so that the sealing strip can keep good sealing performance under pressure at any time. The doors and windows of wangmei are all European standard hardware.
Wangmei doors and windows perfectly combine profiles, hardware, locking points, glass, adhesive strips and so on to make a system of energy-saving windows to ensure your quality of life.
