Which framing element attaches directly to the foundation to prevent moisture from rising through wood?

• A. Stud
• B. Flashing
• C. Sillplate
• D. Joist

Answer: (C)

The base piece that connects the wall to the foundation is the sill plate. It rests directly on the foundation and is usually pressure‑treated to resist moisture; it’s fastened to the concrete with anchor bolts to create a solid base for the wall framing above. A sill plate keeps wood framing elevated from direct contact with concrete, helping to reduce moisture transfer into the wood and often pairs with a sill seal to block capillary rise. The other items have different roles: a stud is the vertical member of the wall, a joist is a horizontal member for floors or ceilings, and flashing is a moisture-management material used at joints to shed water, not the base framing element.
