Wind pressure calculations are essential for selecting windows and doors for high-rise buildings. According to the "Code for Design of Building Structures" GB 50009-2012, the basic wind pressure values vary depending on the building's height and the region. Taking Chifeng as an example, the basic wind pressure is approximately 0.55 kN/m², while the standard wind pressure value for the exterior facade of a 30-story high-rise building can reach over 1.5 kN/m².
The selection of window and door profiles for high-rise buildings also requires attention to the material and width of the thermal break strip. PA66 nylon thermal break strips are the standard configuration required by national standards, and their transverse tensile strength must reach ≥24 MPa. PVC thermal break strips, due to their poor weather resistance and insufficient strength, should not be used in windows and doors for high-rise buildings.
