With the improvement of people's economic income level, everyone begins to pay attention to quality life. Home is the harbor for everyone to relax. The comfort and aesthetics of home environment have become an important element in improving quality life.
Doors and windows have changed from the previous function of preventing wind and rain to the direction of beauty, safety, energy saving and intelligence.
The air tightness and water tightness of traditional doors and windows are poor, and rainwater infiltration will occur when several Typhoon rainstorms occur, which brings troubles to owners and cannot withstand the test of time. According to the research of experts for many years, the air tightness of high-end system doors and windows needs to reach Level 8, the water tightness needs to reach level 7, and the doors and windows with a K value of 1.6 can be regarded as doors and windows with high heat insulation. The sound insulation value needs 30-35 decibels to ensure high sound insulation effect. In downtown, streets and traffic routes, as long as the windows are closed, the noise will be reduced by more than 30 decibels instantly to achieve sleep quality. As for the high wind pressure resistance, it needs to reach Level 8, so that the doors and windows can withstand the wind and rain in the 100-meter-high layer of violent wind and rainstorm, and will not be deformed due to the influence of high-strength wind. High-end system doors and windows have six remarkable characteristics. They are high air tightness, high water tightness, high heat insulation, high sound insulation, high wind pressure resistance and low energy consumption.
High-end system doors and windows are an organic combination of performance systems. A series of important functions such as water tightness, air tightness, wind pressure resistance, heat insulation, sound insulation, anti-theft, Operation feel and so on need to be considered. Equipment, profiles, the comprehensive performance results of parts, glass, viscose and seals are indispensable, and finally form high-performance system doors and windows. The main factors affecting the quality of doors and windows are:
1. Profiles and glass
after good surface treatment, high-quality aluminum profiles have good ability to resist atmospheric corrosion, moisture-proof, sun-proof, high-temperature resistant deformation, anti-low temperature embrittlement, flame-proof, anti-aging, lightning protection, lasting stability, suitable for all kinds of climate. Glass should be tempered glass certified by 3C.
The quality of profiles and glass directly determines the quality of doors and windows. The doors and windows produced by inferior profiles have low strength, easy fading and deformation, and poor safety of ordinary glass.
2. Hardware and accessories
hardware is the main factor that determines the quality of the whole window. The quality of hardware accessories of doors and windows largely determines the service life of doors and windows. The price of good brand hardware and inferior hardware is several times or even more than ten times. Gold steel voile, the price difference of sealant strip, foaming agent, waterproof adhesive and other accessories is very large.
3. Processing technology
production equipment and technological level determine whether the overall performance of doors and windows is excellent. The doors and windows of high-end aluminum alloy system adopt washing processing and numerical control cutting, and corner glue should be used when setting corners to ensure sealing performance.
Inferior aluminum alloy doors and windows, blindly choose aluminum profile series and specifications, rough processing, saw cutting instead of milling processing, not installed as required, poor sealing performance, not only air leakage, rain leakage and glass cracking phenomenon, moreover, in case of strong wind and external force, it is easy to scrape or bump the push and pull part or glass, damaging things and hurting people.
4. Installation process
1. The geometric size error of doors and windows is within 5mm, and 2cm gap is reserved between window frame and wall.
2. The gap between the window frame and the wall is filled with high-strength foaming agent, which requires filling full and seamless.
3. The gap between the inner and outer window frames and the wall is waterproof adhesive, which requires smooth and tidy, no fracture and no foaming.
4. Lightning protection grounding device must be installed for high-rise doors and windows above the 15th floor.
