What is a characteristic of Type III Ordinary construction?

Type III Ordinary construction refers to a building method where the exterior walls are made from noncombustible materials, such as masonry or metal, while the interior can incorporate wood and other combustible materials. This combination allows for better fire resistance in the walls that face the exterior, while also enabling the use of traditional framing methods for interior structures, typically made of wood.

The noncombustible exterior walls help improve the building's fire rating, making it less susceptible to igniting from external sources. However, the presence of partial wood interiors can create fire hazards if not properly managed, as wood is combustible and can contribute to the spread of fire within the structure. Therefore, Type III Ordinary construction is well-known for balancing fire safety with the practicalities of using wood in building interiors, which is characteristic of many ordinary buildings, such as warehouses and other commercial structures.
