ISO Construction Classes Explained
Frame construction (Class 1) is the least fire-resistant and typically least expensive to rebuild, while fire-resistive construction (Class 6) uses reinforced concrete and structural steel, costing significantly more to replace but offering superior fire and wind performance.
Frame (Class 1)
Wood-framed construction, least fire-resistant and typically least costly to rebuild.
Joisted Masonry (Class 2)
Masonry walls with wood or light steel roof/floor structure.
Non-Combustible (Class 3-4)
Metal or light-gauge steel structure with non-combustible walls.
Fire-Resistive (Class 6)
Reinforced concrete and structural steel, highest replacement cost.
