What is one of the main advantages of using gypsum drywall?

  1. High labor cost

  2. Fire resistance

  3. Poor sound control

  4. Complex installation

The correct answer is: Fire resistance

One of the main advantages of using gypsum drywall is its fire resistance. Gypsum contains water molecules in its composition, which helps to resist fire by slowing the combustion process and preventing flames from spreading quickly. When exposed to fire, the water evaporates and helps to cool the surface, giving occupants more time to evacuate and reducing the risk of smoke damage. This characteristic makes gypsum drywall particularly valuable in residential and commercial buildings, where fire safety regulations are crucial. In contrast, the other options do not align with the benefits offered by gypsum drywall. High labor cost is typically not a feature associated with drywall installation, as it is generally considered an economical building material. Poor sound control does not represent a strength of gypsum drywall, as it can actually provide decent sound attenuation when properly installed. Additionally, the installation of gypsum drywall is not inherently complex; it is relatively straightforward, especially when compared to other materials, making it easier for contractors to work with.
