What is the main goal of fireblocking in construction?

Fireblocking is primarily aimed at restricting the spread of fire within concealed spaces in a building. This is crucial for maintaining safety during a fire incident, as concealed spaces—such as those found in wall cavities or floors—can act as conduits for fire to travel quickly and unhindered throughout a structure. By implementing fireblocking techniques, such as the installation of specific materials that can withstand high temperatures and prevent flames from passing through, the integrity of the building is better protected, which can lead to increased time for evacuation and reduced overall damage.

In addition to safety, fireblocking can also help to contain smoke and toxic gases, which are often more dangerous than flames themselves during a fire. This aspect of fireblocking plays a vital role in fire protection strategies mandated by building codes and regulations, ensuring that structures are designed with safety as a priority.
