Characteristics of Aluminum Alloy Doors and Windows with Different Opening Forms - Product Series
(2) Product Series
Generally speaking, under the same conditions of door and window structure, specification, and profile wall thickness, when the product series increases, the cross - sectional dimension of the door and window profile increases, the wind - pressure - resistant performance of the door and window improves, the weight per meter of the profile increases, and the cost of the door and window also increases accordingly. When designing and selecting the product series of aluminum alloy doors and windows, it should be reasonably selected on the premise of meeting the performance requirements of the doors and windows.
(3) Window Type Design and Selection
Up to now, aluminum alloy doors and windows have formed a relatively complete series of universal standard window types, which can meet the needs of aluminum alloy doors and windows for most buildings. Therefore, under normal circumstances, when designing the window types of then, standard window types should be selected as much as possible according to the different requirements of the project to achieve the purposes of facilitating design, production, construction, and reducing costs.

When selecting window types, the following factors should be fully considered for reasonable selection.
① Select window types and series that are suitable for the region, environment, and building type.
② Meet the physical performance requirements such as wind - pressure - resistant performance, watertight performance, airtight performance, and thermal insulation performance of doors and windows.
③ Meet the functional requirements such as lightning protection, fire prevention, and safety.
China has a vast territory. From the frigid three provinces in the northeast to the hot Hainan Island in the south, from the dry northwest inland to the rainy southeast coast, the climate environment varies greatly. At the same time, various buildings also have different building functions and architectural decoration requirements.
Therefore, when designing and selecting the window types of aluminum alloy doors and windows, the design and selection should be carried out correctly and reasonably according to the climatic characteristics of each region and the requirements of architectural design.
For example, in the severe - cold northern region, the climate is cold in winter. The thermal insulation performance and airtight performance of aluminum alloy doors and windows are the primary considerations. Inward - opening side - hung or inward - opening bottom - hung aluminum alloy doors and windows with good thermal insulation performance composed of high - airtight - performance thermal - insulation profiles and Low - E insulating glass should be selected.
In the hot - summer and warm - winter southern region, there are often violent storms and the climate is hot. Attention should be paid to the wind - pressure - resistant performance, watertight performance, and sun - shading performance of aluminum alloy doors and windows. Aluminum alloy doors and windows with sun - shading function that meet the requirements of wind - pressure - resistant performance and watertight performance can be selected.
Under special circumstances, if the existing aluminum alloy doors and windows cannot meet the requirements of architectural design, at this time, some profiles of the existing they can be redesigned according to the requirements, or even the whole can be redesigned.
Since the development of a new door and window system must involve the design, mold - opening, trial - molding of profiles and hardware fittings, product trial - production, type test, and finalization, etc., the project cost will be greatly increased and the construction period will be prolonged. Therefore, whether it is necessary to redesign the window type should be carefully determined after comprehensively considering factors such as project requirements, project cost, and construction period.
