There is so much new knowledge in the door and window industry, how much do you know?
Door and window products are a comprehensive product composed of various material configurations. Including aluminum profiles + glass + hardware accessories + seals and other accessories. The first three categories have an impact on the performance and grade positioning of door and window products. The last category is about details and is equally important. Any high-end product has high requirements for the above four categories and is made through strict and precise processing technology. The improvement of a single category cannot reflect the level of the product.
A. Aluminum profile configuration considers the following four aspects
① Brand selection ② Surface treatment selection ③ Functional structure selection ④ Profile material selection
B. Glass configuration considers the following two aspects
① Brand selection ② Variety selection
C. The following two aspects should be considered when configuring hardware accessories
① Brand selection (divided into domestic and foreign brands) ② Configuration of main accessories (such as handles, hinges, etc.)
Window function structure classification
Sliding window - more traditional product structure, convenient to use, but generally not high performance, poor safety performance, not suitable for medium and high-end buildings, especially some large and medium-sized cities have clearly stated that high-rise buildings cannot be used.
External casement window/external hanging window - more traditional product structure, in line with Chinese usage habits, comprehensive performance is also high, but there are safety risks, high-rise, and super high-rise buildings should be used with caution.
Inward opening/inward opening and tilting window - European product structure, reduce safety risks, meet the safety requirements of the building, but generally the comprehensive performance is worse than the external flat window, especially the watertight performance, there are greater risks in coastal typhoon areas, so use with caution.
Transverse outward opening window - the structural variation of the external casement window, generally suitable for high-end office buildings, high cost, high operation requirements, not suitable for general commercial housing.
Lifting window - American structure, suitable for the selection of smaller opening windows (1200mm wide x 1800mm high or less), temporarily does not meet the requirements of Chinese architectural design.
Center-hung window - also a variation of the external casement window, avoiding the problem of window wiping, improving the safety factor, but reducing the overall performance.
Inward sliding window - high-end product, suitable for high-end high-rise buildings. It combines the functional advantages of sliding and inward opening/inward opening and tilting windows, developing a window type that avoids the shortcomings of both. Others In summary, the current domestic high-end buildings are mainly inward opening or inward opening and tilting, which not only meets the safety requirements but also meets the national energy-saving requirements.
Classification of door function structure
Sliding door - traditional product structure meets the requirements of a full range of buildings.
Outward opening door - traditional product structure meets the requirements of a full range of buildings.
Inward opening door - traditional product structure meets the requirements of a full range of buildings.
Folding door - suitable for buildings with openings over 2800mm wide, wide field of vision, and beautiful landscape; however, the regular maintenance rate of this product structure is high, the operation needs to be regular, and the maintenance cost is high, which is a mid-to-high-end product.
Lifting sliding door - suitable for buildings with openings over 4000mm wide or high comprehensive requirements, it is a high-end product with a wide field of vision and a single glass width of about 2000mm.
Inward sliding door or inward sliding door - higher performance than the conventional sliding door, meeting high-rise or high-performance requirements, and is a mid-to-high-end product. Others Comprehensively, the current domestic high-end buildings mainly use folding doors and lifting sliding doors when the openings meet the requirements.
Process conditions for door and window products
1. Sealing issues for profile splicing: glue injection at corners, frame/middle column or middle column/middle column, glue injection at splicing parts
2. Connection issues between doors and windows and building walls: installation method of attached frames, connection treatment between frame materials and building wall decoration surfaces
3. Basic requirements: accuracy of processing equipment, factory environment, level of workers, process management system, installation management system
