In ordinary construction, what are exterior walls made of?

Exterior walls in ordinary construction are typically made from masonry or other non-combustible materials. This choice highlights the importance of using materials that resist combustion, which enhances the overall fire safety of a structure. Masonry, such as brick or concrete blocks, is valued for its strength and fire-resistant properties, making it a common choice for building exterior walls. These materials contribute to the building's structural integrity and serve as a barrier to the spread of fire, protecting both the structure and its occupants.

Understanding the composition of exterior walls is crucial in fire investigations, as the materials used can significantly impact how a fire behaves, how quickly it may spread, and what safety measures are necessary during and after a fire incident. Consequently, knowledge of the typical materials used in construction aids in assessing fire risk and developing effective prevention strategies.
