Definition
Sills are the horizontal timbers of a house which either rest upon the masonry foundations or, in the absence of such, form the foundation.
Purpose
The purpose of sills is to provide a base for the structure, distributing loads from the walls and framing to the foundation or ground.
Examples of Use
- In timber-framed houses, sills provide a stable base for the vertical posts and wall framing.
- In historic buildings, wooden sills rest directly on stone or brick foundations.
- Modern construction uses treated wood or composite materials for sills to resist decay and pests.
