The major difference between fire-resistive construction and noncombustible construction is _____.

• A. Fire-resistive steel must be protected from heat
• B. Fire-resistive construction uses only wood
• C. Fire-resistive uses glass insulation
• D. Noncombustible requires insulation

Answer: (A)

The key idea is how heat affects the structure and how each construction type handles it. In fire-resistive construction, the goal is to keep critical structural elements from losing strength during a fire, which means protecting steel or other load-bearing members with fireproofing material or protective systems. This protection ensures the element can perform for a designated period under high temperatures. Noncombustible construction, on the other hand, relies on materials that inherently do not burn, so their fire resistance comes from the material itself rather than an added protective coating. That’s why the major difference is that fire-resistive steel must be protected from heat. The other options aren’t the defining distinction: it doesn’t require using only wood, it isn’t about glass insulation, and insulation needs aren’t what sets noncombustible construction apart.
