Is it ok to install fresh air system on the outer wall of high-rise residential building by punching holes?

Outdoor air system can be installed on the exterior wall of high-rise residential buildings, but it must be approved by the property. If it is a load-bearing wall, it is necessary to ask the property to go to the door to see which positions can be punched, and find an experienced professional master to ensure the quality of punching. The location of the opening must avoid the basic structures such as steel bars and iron wires in the load-bearing wall. We must not destroy the infrastructure excessively, which will affect the structural stability and anti-destructiveness of the house, or even make it impossible to repair it. Finally, it should be sealed to prevent rainwater from flowing backwards.

Rules for punching holes in external walls

Without the consent of the original design unit or the design unit with corresponding qualification grade, the main body and load-bearing structure of the building shall not be changed. The original energy-saving facilities of the house shall not be damaged, and the external wall shall not be changed at will. It is very dangerous to hit the pipeline buried in the wall when drilling holes. Shall not engage in other acts that affect the safety of building structure and use.

If the external wall is not a load-bearing wall or a structural frame bearing the weight of the main body, then there is no need to worry about safety and violation when punching holes in the external wall.
