NFPA 220 fire resistive ratings for type V construction indicate which construction type?

NFPA 220 fire resistive ratings for type V construction indicate which construction type?

• A. Type II
• B. Type III
• C. Type IV
• D. Type V

Answer: (D)

NFPA 220 ties fire-resistance ratings to the construction type, and Type V is defined as wood-frame, combustible construction. When fire-resistance ratings are described for Type V construction, they’re talking about a wood-frame building. So the construction type indicated by these ratings is Type V. The other construction types refer to noncombustible or different framing systems (Type I and II are noncombustible, Type III is mixed exterior/noncombustible interior, Type IV is heavy timber), which are separate categories and not what Type V ratings describe.
