What type of construction features noncombustible exterior walls with wooden interior?

Type 3 construction, often referred to as "ordinary" construction, is characterized by having noncombustible exterior walls, typically made of masonry or steel, with an interior that is primarily made of combustible materials such as wood. This type of construction is common in buildings where the exterior is designed to resist fire spread from the outside while allowing for more flexibility and lower costs in interior construction materials.

This type of construction can be seen in many commercial and residential buildings, where the exterior walls provide a degree of fire resistance and stability, while the interior framing and finishes are often made from wood or other combustible materials. The combination allows for both structural integrity and cost-effectiveness.

In contrast, Type 1 construction involves noncombustible materials throughout and offers the highest level of fire resistance. Type 2 construction also uses noncombustible materials but may not offer the same level of fire resistance as Type 1. Type 4 construction features heavy timber framing, which provides significant fire resistance but is still largely made from wood. Therefore, Type 3 is the best fit for the scenario described.
