• Affordable and available in various sizes/thicknesses. 

• Most common type for residential use (bedrooms, living rooms, hallways). 

Fire-Resistant Drywall 

• Slows flame spread with a gypsum core containing chemically bonded water (21%), which releases steam under heat.

  • Type X: minimum 1-hour fire rating; used in firewalls, stairwells, and shafts. 

  • Type C: 2–4-hour fire rating; higher vermiculite/glass fibre content; ideal for ceilings.
