What is the difference between Type C drywall and type X?
Type C drywall is known as the more durable version of Type X—there are more glass fibers in this product as well as more vermiculite components, giving it a fire resistance of 2-4 hours. You can find this product at your local drywall and insulation store in 1/2” and 5/8” thickness.
What is Type X plasterboard?
