Type 3 Construction is typically used in which buildings and what is true about exterior walls?

• A. Heavy Timber, Large Dimensioned lumber.
• B. Exterior walls are non-combustible.
• C. Used in schools, churches, mercantile. Exterior walls are non-combustible.
• D. Non-load-bearing partitions inside.

Answer: (C)

Type 3 construction uses noncombustible exterior walls with interior framing that is often wood. This setup provides a fire-resistant exterior envelope while keeping interior construction more economical. Because of that, it’s commonly found in public commercial buildings such as schools, churches, and mercantile structures. The exterior walls being noncombustible is a defining feature, helping to slow fire spread through the wall assembly and maintain a safer exterior. Inside, the framing can be wood and is typically load-bearing, so non-load-bearing partitions aren’t what defines this type.
