In building; sarking refers to the boards placed between the rafters and the roof (sometimes called the 'soffit').
In building; a screed is a thin level layer of material usually applied to floors.
In solar PV manufacturing; a semiconductor is any material that has a limited capacity for conducting an electric current. Certain semiconductors, including silicon, gallium arsenide, copper indium diselenide, and cadmium telluride, are uniquely suited to the photovoltaic conversion process.
In building; a septic tank is a tank constructed or manufactured to accept sewerage when no mains system is available.
In building; a sleeper wall is a wall used to support the ground floor, usually honeycombed in construction to provide ventilation.
In building; the snow line is considered to be 500 feet above sea level. It is the theoretical altitude at which land is expected to suffer from severe winter conditions.
In building; a soffit is the underside of an architectural element, for example an arch or the eaves.
In building; the term soft landscaping applies to elements including topsoil, plants, shrubs and trees.
In solar system design; the solar spectrum is the total distribution of electromagnetic radiation emanating from the sun. The different regions of the solar spectrum are described by their wavelength range. The visible region extends from about 390 to 780 nanometers (a nanometer is one billionth of one meter). About 99 percent of solar radiation is contained in a wavelength region from 300 nm (ultraviolet) to 3,000 nm (near-infrared). The combined radiation in the wavelength region from 280 nm to 4,000 nm is called the broadband, or total, solar radiation.
In solar system design; solar thermal electric systems are solar energy conversion technologies that convert solar energy to electricity, by heating a working fluid to power a turbine that drives a generator. Examples of these systems include central receiver systems, parabolic dish, and solar trough. These are only used in large commercial systems.
In building; a soleplate is a substantial horizontal section of timber or metal, fixed to the floor slab.
In building; a stanchion is a vertical supporting beam usually made from steel.
In building; stone cladding is a thin layer of stone or imitation stone that is attached to the external wall of a property.
In building; a string or stringer is one of the parallel boards supporting the treads.
In building; strip foundations are concrete filled trenches used to support a building.
In property; a structural survey is the most wide ranging of surveys. It is carried out by a professional surveyor.
In building; a strut is an upright roof timber connected to the rafter above it or sloping to connect another post to the rafter.
In building; a stud wall is an internal wall made from a wooden frame rather than brick.
