Which of the following is NOT a type of construction that can utilize combustible materials for fire walls?

Type I construction is characterized by non-combustible materials, specifically designed to withstand high temperatures and resist fire spread. This type of construction typically utilizes concrete or steel, which helps ensure that fire walls are made of non-combustible materials, enhancing the overall fire resistance of the building.

Type II construction, similar to Type I, employs non-combustible materials, but may not be as robust. Nonetheless, it maintains the principle of using non-combustible elements in critical structures like fire walls.

Type III construction combines both combustible and non-combustible materials, often using combustible framing and non-combustible exterior walls. This type allows for some flexibility regarding fire walls but still adheres to certain restrictions.

Type V construction is where combustible materials are most frequently used. It is often entirely made of wood framing, allowing for a greater utilization of combustible materials for elements such as fire walls.

Thus, identifying that Type V is the construction type that allows for the use of combustible materials in fire walls distinguishes it from the other types that either restrict this or utilize non-combustible materials entirely.
