What type of assembly is constructed of components not defined as noncombustible?

A combustible assembly is defined by its construction using materials that are not classified as noncombustible. This means that the components within the assembly can ignite and burn when exposed to fire, potentially contributing to the spread of flames and smoke. In building codes and fire safety regulations, combustible assemblies are typically treated differently than noncombustible assemblies due to their impact on fire safety protocols.

This classification is critical in determining the fire resistance rating of a structure and ensuring that buildings are designed to minimize fire hazards and protect occupants. Understanding the difference between combustible and noncombustible materials is essential for effective fire safety planning and compliance with local code requirements.
