Which type of construction requirements must APA-rated plywood meet?

• A. Class A and 1 hour fire resistant
• B. Class B and 30 minute fire resistant
• C. Class C and non-combustible
• D. Class D and flammable

Answer: (A)

APA-rated plywood must meet specific construction requirements that focus on fire resistance and classification standards. The correct classification for this type of plywood is Class A and it must have a 1-hour fire-resistance rating. Class A indicates that the material has the highest level of fire resistance, making it suitable for use in applications where fire safety is a significant concern.

In the context of building codes and fire regulations, the need for a 1-hour fire-resistance rating showcases the material's capability to withstand the effects of fire for a sufficient period, providing valuable time for evacuation and reducing the risk of fire spread. This is especially important in structural applications, where maintaining integrity during a fire is crucial for safety.

The other classifications outlined in the incorrect options represent lower levels of fire resistance or different fire classifications that are not applicable to APA-rated plywood. Thus, the requirements for Class A and a 1-hour fire-resistance rating reflect the expected performance standards for this type of building material.
