What is the advantage of Type-X drywall?

1. It is less costly than normal drywall

2. It comes pre-painted

3. It is fire resistant

4. It is mold resistant

The correct answer is: It is fire resistant

Type-X drywall is specifically designed to provide enhanced fire resistance. Its composition includes additives that help it withstand elevated temperatures and slow the spread of fire, making it an essential material in areas where fire safety is a concern, such as in multi-family residential buildings, commercial properties, and structural components. The construction of Type-X drywall typically features a thicker core and additional fibrous materials, which contribute to its superior performance in fire-rated assemblies compared to standard drywall. This fire resistance is typically tested according to standards set by organizations like the Underwriters Laboratories (UL) or the American National Standards Institute (ANSI), resulting in specific ratings that determine how long the drywall can withstand fire exposure before igniting. While factors like cost, pre-finishing, and mold resistance are important in the selection of drywall for various applications, they do not provide the critical safety benefit found in Type-X drywall. This distinction underscores the significance of its fire-resistant attributes, which serve to protect lives and property in the event of a fire.
