Sill
'Sill' can refer to at least three different things around a home.

The first, and perhaps most common is a window sill. The sill on a window is the flat piece inside the window, just below the bottom sash. For a picture of the parts of a window, follow the link or visit the window section using the menu to the left.

The second sort of sill is the piece that is underneath a door. If you were to open a door, step into the door frame, and look directly down, you would be looking at the sill. Usually, there is only a sill for exterior doors, since there is a need to block the weather from penetrating around the door. With older doors, this sill can be made of oak, usually with a 2x8 or 2x10 profile.

The third sort of sill is the piece that goes around the top lip of a foundation. Usually, it's a layer of 2x6 pressure treated lumber that rests directly on the concrete of the foundation. It is then connected with anchor bolts that have been set into the concrete. This allows the framing lumber of the walls and floor system to attach to wood, and does not weaken the conrete by driving lots of spikes into it. The sill is usually pressure treated, so that any moisture that may remain in the concrete will not easily penetrate the rest of the frame.
