What is fireblocking made from?

Fireblocking is primarily made from wood or similar materials used for partitioning within a building. These materials act as barriers to slow down the spread of fire through concealed spaces, such as wall cavities or ceilings. The purpose of fireblocking is to help contain a fire to one area of a structure and prevent it from traveling through these hidden spaces.

Using wood or similar materials ensures that fireblocking can be effectively integrated into standard building practices while providing the necessary structural support. It also allows for easier construction and installation compared to other materials. Unlike metal barriers, which may be more appropriate for specific applications, or concrete, which is often utilized in fire-rated assemblies, wood-based fireblocking is focused on addressing the gaps at intersections or joints of different building components. Additionally, fiberglass insulation is intended for thermal protection and does not serve the primary function of controlling fire spread as effectively as fireblocking made from wood or similar materials.
