Are ducts allowed to penetrate fire walls?

Ducts can penetrate fire walls under specific conditions that comply with building codes and fire safety regulations. The key factors that allow this include the use of fire-rated ducts or appropriate firestop systems that ensure the fire resistance of the wall is maintained. These systems are designed to prevent the spread of fire, smoke, and gases through the openings when ducts pass through fire-rated walls.

Additionally, installations must meet the requirements of the local building code, which may stipulate specific materials and methods for penetrating fire-rated assemblies. Therefore, while ducts are generally permitted to penetrate fire walls, it is crucial that the installation adheres to these safety measures to ensure the overall integrity of the fire barrier is not compromised. This understanding is vital for maintaining the safety and functionality of commercial buildings.
