The selection of door and window opening forms: Different opening forms of doors and windows have a certain range of applicability, and should be reasonably selected based on usage requirements, opening size, technical and economic factors, material supply, and processing and manufacturing conditions. When determining the opening size, attention should be paid to the structural characteristics of various opening forms to ensure the necessary volume size. The specifications of doors and windows should be minimized, the types of windows should be reduced, material specifications should be unified, cutting should be simplified, and the standardization and interchangeability of doors and windows should be considered to create conditions for factory production.

The purpose and characteristics of various door and window opening forms:
1. Side hung windows: (external side hung, internal side hung): Side hung windows have a simple structure, are most commonly used for shading, and are easy to install screen windows. The drainage problem of external windows is easy to solve and does not occupy indoor space when opened, but there is a disadvantage of being blown away or damaged by the wind when the fan is turned on. It is inconvenient to wipe the window glass when the curtains are not neat. The problem of cleaning the glass should be solved by opening the window. When the windows outside the building are opened, the sashes are odd numbered (1, 3, 5), and the middle sash is fixed. Cleaning the windows is unsafe, so the design should consider the issue of easy window cleaning.
There are two basic methods to solve strange external opening windows:
(1) The central fan is designed with a special opening mode, such as internal opening, transfer fan, or push-pull.
(2) Use a dedicated device to turn on the side fan together with the window frame, leaving an appropriate distance.
2. Sliding window: (horizontal sliding, vertical sliding): Sliding windows do not occupy indoor space, and the window sash is in good stress state, suitable for installing large areas of glass, but the ventilation area is limited.
3. Suspended windows: (upper, lower, middle): External suspended windows have better rainproof effect, but due to the limitation of opening angle, the ventilation effect is poor. Interior hanging windows occupy indoor space and are often used for rooms with special requirements or high indoor windows. Mid hung windows have a simple structure and good ventilation effect, and are often used for high side windows.
4. Louvers: There are two types of blinds: fixed and movable. Louvers generally have functions such as ventilation, shading, waterproofing, and blocking the line of sight. When the requirements for rain and light protection are high, movable or irregular fixed blades can be used. If there are lighting requirements, transparent or semi transparent blades can be used.
5. Traditional residential windows: Traditional residential windows are not only suitable for traditional residential buildings, but also for garden buildings such as tea rooms, restaurants, cultural parks, cultural centers, and so on. In the past, wood was used as traditional residential windows, but with the development of chemical building materials, PVC plastic profiles or aluminum profiles can also be used to make them. But the surface treatment should imitate wood.
