What characterizes Type 3 construction?

Type 3 construction is characterized by having masonry exterior walls, which typically provide greater fire resistance compared to fully combustible materials. This type of construction is often used in commercial buildings where a combination of structural integrity and aesthetic appeal is necessary. The masonry serves as a protective barrier that helps to prevent the spread of fire from the exterior, while the interior components may consist of more combustible materials like wood or light-framed construction.

Understanding this classification is essential, as it impacts not only building design but also fire suppression strategies, safety regulations, and the expected behavior of fire in such structures. The presence of masonry walls distinguishes this type from others that may have a purely wood framework or other less fire-resistant attributes.
