Young Black Haired Girl Undresses Her Panties Above The Couch On The Window Sill Plate With Pillows

There are rare examples of historic buildings in the U.S. where the floor joists land on the foundation and a plank sill or timber sill sit on top of the joists. Another rare, historic building technique is for the posts of a timber frame building to land directly on a foundation or in the ground (Post in ground) and the sills fit between the posts and are called "interrupted sills".
Stick framing
In modern, wood construction sills usually come in sizes of 2×4, 2×6, 2×8, and 2×10. In stick framing (construction) the sill is made of treated lumber and are anchored to the foundation wall, often with J-bolts to keep the building from coming off the foundation during a severe storm or earthquake. Building codes require the bottom of the sill plate is kept 6 to 8 inches above the finished grade. This is a building code requirement to hinder termites and prevent the sill plate from rotting.
