What characterizes structures in Class 4 - Masonry Noncombustible?

1. Wooden roofs and floors with masonry walls

2. Masonry exterior walls with metal roofs

3. All elements constructed from wood materials

4. Noncombustible materials used exclusively throughout

The correct answer is: Masonry exterior walls with metal roofs

Structures classified as Class 4 - Masonry Noncombustible are characterized by their use of masonry exterior walls paired with metal roofs. This classification indicates that while the walls are constructed from masonry materials, which are noncombustible, the roofs made of metal further enhance the overall fire resistance of the structure. The combination of these materials plays a significant role in reducing the fire risk, as masonry does not burn and metal has a high melting point. The other options described do not fully align with the characteristics of Class 4. For instance, wooden roofs and floors with masonry walls would introduce combustible materials, which contradicts the noncombustible requirement. Structures made entirely of wood materials do not qualify for this classification due to their combustibility. Lastly, the use of noncombustible materials exclusively throughout the structure is a broader definition; Class 4 specifically focuses on the pairing of masonry walls with metal roofs rather than an entire structure being noncombustible. Thus, the emphasis on masonry exteriors and metal roofs is what distinctly defines this classification.
