In this rainy and changeable season, It is also a time to test the quality of doors and windows at home. Only choose the right doors and windows, So I can enjoy it with confidence. NO.1 Windproof performance of profile It is an important feature of doors and windows, especially for high-rise residential windows. We use high-quality multi-cavity structural profiles with high strength, so they are corrosion resistance, oxidation resistance, and high toughness.Our workshop achieve high-precision cutting by advanced equipment .Tight joint can shelter homes from wind and rain. NO.2 Compressive performance of glass Glass has always been an important part of home improvement doors and windows, occupies 80% of the entire door and window area, and have a great performance in weatherproof. We use automotive-grade hollow safety double-layer glass certified by the national 3C, which has good compression and impact resistance, high flatness, and superior water tightness and air tightness.And all series of glass products have been purchased with insurance, so that users can be more assured. NO.3 Sealing structure of doors and windows It directly affects the air-tightness and water-tightness of doors and windows. The rigorous sealing structure design can prevent water vapor from entering and rainwater leakage which to keep the house dry. We use EPDM with superior sealing performance, which is resistant to aging, does not fade and seals well. In addition, the 90°corner adopts a special glue angle to transfer the integral continuous sealing surface of the profile, which ensures that the doors and windows have excellent sound insulation, waterproof and windproof performance. NO.4 Drainage design of doors and windows If the drainage is not done well, water leakage and seepage are more likely to occur on rainy days. We have a variety of different drainage designs to meet different opening methods of door and window products, which are practical and beautiful. Smooth drainage ensures strong watertight performance, allowing unobstructed drainage of doors and windows. NO.5 corner assembly process of doors and windows It has a great influence on the air tightness of doors and windows. If the assembly structure is unreasonable, the gap between the window frames will be too large, finally cause air and rain leakage. We use cast aluminum corner code with stainless steel pin glue injection technology, which greatly improves structural strength,sealing performance,and safety. It helps corner connection strength to be higher;corner code glue to be more reasonable and corner sealing performance to be better.

With the continuous improvement of the quality of life, people have higher and higher requirements for the quality of housing. As an important part of the overall function of the building, doors and windows are more and more valued by consumers. Therefore, the system doors and windows with excellent performance, high comfort, and good durability are widely concerned by consumers, and the high-performance system doors and windows gradually come into the view of the general public. 1. What are system doors and windows? Most consumers usually pay more attention to product appearance, price, and other factors when they buy doors and windows. I don't know about some professional performance of doors and windows. So many people know little about system doors and windows, even think that as long as it is high-quality doors and windows can be regarded as system doors and windows. A real system door and window is a perfect organic combination of performance systems. It needs to consider a series of important functions, such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance, operation feel, etc. it also needs to consider the comprehensive results of the performance of equipment, profiles, accessories, glass, adhesive, seals, etc Form high-performance system doors and windows. 2. What are the highlights of the core technology of the system doors and windows? At present, in the market of building materials, the aluminum alloy doors and windows with broken bridge and partition profiles have gradually become the first choice of many high-end building windows. In addition to paying attention to the quality of obvious parts of doors and windows, such as aluminum, glass, and accessories, the system pays more attention to the realization of a comprehensive performance after the combination of these parts. The quality of the system doors and windows not only depends on the material and accessories but also depends on the installation technology and sealing process of the parts. The doors and windows of the Hihaus system adopt an automobile-grade sealing strip at the closure, and the whole window sash adopts four seal design, which is better in windproof grade, heat insulation, dust, and waterproof performance. The safety is also higher. The opening and closing rubber strip are made of an EPDM foamed composite rubber strip and composite co-extrusion process. It has good resilience and greater compression, which can effectively ensure good air-tightness and better sealing of the system doors and windows. 3. Why is the quality stability of doors and windows high? Ordinary doors and windows are assembled by ordering different parts according to their own needs, often without comprehensive testing. Due to the different quality and performance of various parts, the stability of doors and windows is relatively poor. System doors and windows products have stable quality, which benefits from the exquisite system doors and windows technology. A mature system door and window often needs the technical R & D department to carry out repeated R & D and testing for several months or even years for the overall performance, and the mature products will be launched only after reaching the expected goal. At the same time, the technical department will also carry out strict testing and inspection on all parts of the system door and window to ensure the stability of the system door and window.
