Drywall can withstand temperatures up to 176°F (80°C) before it begins to lose its structural integrity. It is made of gypsum which contains water, slowing down heat transmission. However, prolonged exposure to high temperatures can cause it to crumble and fail. For areas exposed to heat, consider fire-resistant drywall options available on the market.

FAQs & Answers

  1. What temperature can drywall safely withstand? Standard drywall can withstand temperatures up to 176°F (80°C) before it begins losing its structural integrity.
  2. Why does drywall lose strength when exposed to heat? Drywall is made of gypsum which contains water; prolonged heat exposure causes the water to evaporate, weakening the drywall and causing it to crumble.
  3. What types of drywall are better for heat resistance? Fire-resistant drywall options, often called Type X drywall, have additives that improve heat resistance and structural stability in high-temperature environments.
