The basis or foundation of a thing; especially, a horizontal piece, as a timber, which forms the lower member of a frame, or supports a structure; as, the sills of a house, of a bridge, of a loom, and the like.
(1) The two-by-four or two-by-six wood plate framing member that lays flat against and bolted to the foundation wall (with anchor bolts) and upon which the floor joists are installed. (2) The member forming the lower side of an opening, as a door sill or window sill.
In a wood-frame house, the sill is a wooden member that rests on top of the foundation (and, per today's building codes, is anchored to it by bolts). In post-and-beam construction, the bottom ends of posts rest on the sill; in a balloon frame, the bottom ends of studs and the ends of floor joists; in a platform frame, the ends of floor joists only. The fixed horizontal member of a window frame, below the sash, is also called a sill.
A molding mounted horizontally at the base of a window. Tied intricately with both the interior and exterior window construction, the sill provides a terminus for the window casing. See details 27, 29 and 30.
The bottom horizontal component of a doorframe. It is the part one walks over when passing through a doorway, sometimes called a threshold. Sills are available in a variety of materials such as oak and bronze or brass anodized aluminum.
A support member laid flat on the top of the foundation wall, used as the base for floor framing; also called the sill plate. Also, the member forming the lower side of an opening, such as a windowsill or doorsill.
the lowest member of a frame (usually wood or metal), which supports the uprights of a frame--most commonly used to describe the lowest horizontal member of an opening, such as a door sill or window sill
(1) The 2 X 4 or 2 X 6 wood plate framing member that lays flat against and bolted to the foundation wall (with anchor bolts) and upon which the floor joists are installed; normally, the sill plate is treated lumber; (2) The member forming the lower side of an opening, as a door sill or window sill
The bottom section of a Window frame installed at a angle designed to shed water away from the inside of a home and seal to the bottom of a window sash. Many sills are equipped with weather stripping to make the seal with the sash weather tight.
The lowest member of the frame of a structure, resting on the foundation and supporting the floor joists or the uprights of the wall. The member forming the lower side of an opening, as in a door sill, window sill, etc.
Rising magma cooling underground which forms in sheets parallel to existing layers. Dikes and sills of Keweenawan time arose among the older Rove Formation which runs from Gunflint Lake east to Superior (our BWCA Region V). More resistant to erosion and glaciation than the surrounding rock, they delineate the long and narrow lakes which are the hallmark of this region.
The lowest member of a wood frame structure that rests on the foundation. It supports the floor joists or uprights of the wall. It can also refer to any member forming the lower portion of an opening, such as a door sill or window sill.
In geology, a sill is a tabular, often horizontal mass of igneous rock that has been intruded laterally between older layers of sedimentary rock, beds of volcanic lava or tuff, or even along the direction of foliation in metamorphic rock. The term sill is synonymous with concordant intrusive sheet.
The upper limit of any variogram model which has such a limit, i.e., which tends to “level off” at large distances. In Geo-EAS, the spherical, gaussian, exponential, and nugget models have sills. For the linear model, “sill/range” is used merely to define the slope.
The sill is the possible variogram value around which the variogram stabilizes when distance increases. Not all variograms have a sill. If a sill exists, the distance where the sill value is reached is called the range. The range is the distance behind which variable values at two points no longer demonstrates any correlation.
