An attic insulation shield should extend at least how many inches above the insulation material?

• A. 1 inch
• B. 2 inches
• C. 3 inches
• D. 4 inches

Answer: (B)

An attic insulation shield is designed to prevent insulation material from blocking airflow and to safeguard the insulation from moisture and other potential damage. The requirement for the shield to extend at least 2 inches above the insulation material ensures there is a proper gap that allows for adequate ventilation. This gap helps maintain the efficiency of the insulation by preventing it from becoming compacted, which can reduce its thermal resistance. Proper ventilation is crucial in attics to prevent moisture accumulation that could lead to mold growth and damage to the roof structure. The 2-inch extension serves as a standard to balance airflow while still providing effective insulation protection.
