Is Sheetrock fire rated?
Hereof, is all Sheetrock fire rated?
Fire-Rated Type X Drywall Basics The thickness of this drywall is 5/8-inch, including all layers. Glass fibers are added to the board to help it retard fire. Also, because it is denser than normal gypsum-and-paper drywall, it takes longer for the fire to degrade it. Most Type X drywall has a one-hour fire rating.
Similarly, you may ask, at what temperature does sheetrock ignite?
Drywall/Gypsum wallboard (GWB) is an accepted fire barrier; however, it is also a huge fuel source for the first few minutes of exposure to a fire or even temperatures higher than 451 Fahrenheit. That's because the paper fascia on gypsum wallboard, even fire rated GWB, is PAPER – paper coated with flammable paint.
