What is the function of draftstopping in building construction?

Draftstopping plays a crucial role in building construction by serving the primary purpose of restricting the spread of fire within concealed spaces, such as attics, ceilings, and wall cavities. This involves the installation of materials or barriers that create effective compartmentalization, slowing down or preventing the movement of smoke and flames in the event of a fire. By limiting the potential for fire to spread quickly through these hidden spaces, draftstopping helps to protect occupants, facilitates safer evacuation, and enables firefighters to manage the situation more effectively.

While enhancing acoustic performance, regulating humidity levels, or aiding in structural load distribution may be important functions in building design and construction, they do not directly relate to the main objective of draftstopping. Understanding the importance of fire safety measures like draftstopping is vital for ensuring that a building complies with safety standards and protects its inhabitants.
