Red Seal Drywall Finisher and Plasterer Practice Exam

What type of drywall is typically used for fire-rated applications?

1. Green board

2. Type X drywall

3. Blue board

4. Standard drywall

The correct answer is: Type X drywall

Type X drywall is specifically designed for fire-rated applications due to its enhanced fire resistance properties. It is manufactured with special non-combustible materials, such as fiberglass, which helps to slow down the spread of fire and provides a greater level of safety in buildings where fire ratings are critical. This drywall is commonly used in areas that require a fire-rated separation, such as walls between units in multi-family dwellings or around mechanical systems. In contrast, green board is moisture-resistant and is typically used in areas with high humidity, while blue board is designed for veneer plaster applications but does not offer fire-rated properties. Standard drywall does not have any specific fire-resisting characteristics and is generally used for non-specialized drywall installations. Therefore, Type X drywall is the correct choice for applications where fire resistance is essential.
