A measure stated as a percentage of the amount of light reflected off a surface.

The ratio of the intensity of light reflected by a material to the intensity of the incident light.

A fitting with different size openings at either end and used to go from a larger to a smaller pipe.

(1) A process in which iron is separated from oxygen with which it is chemically mixed by smelting the ore in a blast furnace.(2) In regard to aluminum, the electrolytic process used to separate molten aluminum from the alumina.

Practice of recovering or diverting content from the solid waste stream, either during the manufacturing process (pre-consumer/post-industrial) or after consumer use (post-consumer). A material can technically be recycled at least once after its initial use phase. At a minimum, the material’s physical and mechanical properties allow it to be re-melted or size reduced and used as filler with similar materials. https://healthymaterialslab.org/tool-guides/hml-resources

To collect and reprocess a material so it can be used again to make a new product. An example is collecting aluminum cans, melting them, and using the aluminum to make new cans or other products. https://healthymaterialslab.org/tool-guides/hml-resources

Blueprints that reflect changes and that are marked with red pencil.

A charge for recording the transfer of a property, paid to a city, county, or other appropriate branch of government.

See Radiation.

Glass having a thin layer of a metal or metal oxide deposited on the surface to reflect heat and light.

Brick masonry construction that has steel reinforcing bars inserted to provide tensile strength.

The relative ability of a surface to reflect sound or light.

A grill placed over a heating duct or cold air return.

A substance that remains a gas at low temperatures and pressure and can be used to transfer heat. Freon is an example and is used in air conditioning systems. The medium of heat transfer that absorbs heat by evaporating at low temperatures and pressure and giving up heat when it condenses at a higher temperature and pressure.

Sound that has struck a surface and "bounced off." Sound reflects at the same angle as light reflects in a mirror; the angle of incidence equals the angle of reflection. Large curved surfaces tend to focus (concave) or diffuse (convex) the sound when reflected. However, when the radius of the reflecting surface is less than the wavelength of the sound, this does not hold true. Thus, a rough textured surface has little effect on diffusion of sound.

Sheet material with one or both faces covered with aluminum foil. Material that reflects and thus retards the flow of radiant heat. The most common type of reflective insulation is aluminum foil. The effectiveness of reflective barriers is diminished by the accumulation of dirt and by surface oxidation.

The ratio of the speed of light in a material to the speed of light in a vacuum.

- To replace a broken window.

Nonmetallic ceramic material used where high temperatures (above 270 degrees F) are present, such as in furnace linings.

The ratio of the amount of water vapor present in the air to that which the air would hold if saturated at the same temperature.
