What is the first piece of wood that is attached to the foundation wall called?

The first piece of wood that is attached to the foundation wall is known as the sill or sill plate. This component serves as a critical element in the framework of a building, as it acts as the base for the vertical framing studs and helps to distribute the weight of the structure above.

The sill plate is typically bolted or anchored to the foundation wall, providing a stable and secure connection that helps prevent shifting or settling of the building. Additionally, it acts as a barrier against moisture that may come from the ground, which is important in preventing rot and other moisture-related issues in the framing of the house.

Understanding the role of the sill plate is fundamental for anyone involved in pest control, particularly in addressing termite management, as termites often nest in or around the sill plate, making it an important area to monitor during inspections and treatments.
