In new construction, where may a metal shield be placed to prevent termite infestation?

• A. Between the foundation and the sill
• B. Between the roof and attic
• C. Between the drywall and studs
• D. Between the footing and grade beam

Answer: (A)

Termite shields work at the first point where wood framing meets the foundation. Placing a metal shield between the foundation and the sill plate creates a continuous barrier that stops termites as they try to move from the soil up onto the foundation and into the wooden framing above. This location is the critical path for preventing infestation because it blocks the termites before they reach the sill and studs. Shields placed in other locations—far above the ground, inside finished walls, or below grade in non-frame interfaces—don’t protect the wood in the same vulnerable connection point.
