At What Temperature Does Drywall Catch Fire? Fire Resistance Explained
Discover how hot drywall must get to ignite and learn about its fire-resistant properties for improved building safety.

Drywall generally needs to be exposed to temperatures of around 451°F (233°C) to catch fire. While drywall is somewhat fire-resistant because of its gypsum core, prolonged exposure to intense heat can cause it to combust. It's essential to ensure adequate fire safety measures in any building, such as smoke detectors and proper insulation, to prevent such risks.
FAQs & Answers
- Why is drywall considered fire-resistant? Drywall contains a gypsum core, which has moisture that helps delay ignition and provides fire resistance under normal conditions.
- Can drywall burn at normal house fire temperatures? Drywall typically needs to reach around 451°F (233°C) to catch fire, so it can withstand many common fire temperatures before combusting.
- What safety precautions help prevent drywall fires? Installing smoke detectors, using proper insulation, and following fire safety guidelines can reduce the risk of drywall catching fire.
- How does prolonged heat exposure affect drywall? Prolonged exposure to intense heat can eventually cause drywall to combust despite its fire-resistant properties.
