One, what are the specifications and models of PVC windows?
1、Window height
Generally, the height, ventilation, and lighting requirements are already determined during the initial stages of construction. Therefore, the height of the PVC windows is typically fixed. Attempting to change it later is not practical. The height of PVC windows also varies depending on the intended use; for example, windows in schools and similar institutions are usually taller than those in residential and office settings. Some PVC windows may require additional protective measures due to insufficient strength. However, for buildings with glass curtain walls, the height is calculated as part of the overall floor-to-floor height, which is typically greater than the height of standard PVC windows.

2、Window width
Some buildings, due to their specific designs, incorporate window structures. When using this design, special attention must be paid to the sliding and opening/closing mechanisms of the aluminum windows in each room. Additionally, the issues related to insufficient natural light and glare caused by this structure need to be addressed. This type of structure is generally not suitable for exhibition and display purposes.
3. Examples of common interior space dimensions for PVC windows:
Living Room: 1.5m x 1.8m - 1.8m x 2.1m; Children's Room: 1.2m x 1.5m - 1.5m x 1.8m; Master Bedroom: 1.5m x 1.8m - 1.8m x 2.1m; Bathroom: 0.6m x 0.9m - 0.9m x 1.4m.
Two. Specifications for Steel-Polymer Fire-Resistant Doors
The dimensions of steel-plastic fire doors are specified. Standard steel-plastic fire door dimensions are typically within 1800mm x 2400mm. For example, the dimensions of a single steel-plastic fire door (width x height) are typically 900mm x 2100mm, while the dimensions of a double-door fire door (width x height) are typically 1200mm x 2100mm.
Of course, in addition to standard-sized fire doors, it is also possible to design fire doors according to the building's design and main function, and then customize non-standard steel fire doors from manufacturers. However, the design must comply with the usage requirements for fire doors.
