Abbr.for “install” or “installation.”
A lock which is actuated automatically (by a spring) as the door is closed.
A fluorescent lamp designed to be started by high voltage without preheating of the electrodes;usually has single-pin base connections;a slimline lamp.
A heater in which there is an exceedingly rapid increase in water temperature as the water flows through tubes surrounding an electric heating coil;best suited for applications requiring a continuous flow of hot water.Must be used with care when the demand is low because accurate temperature control at low flow rates usually is poor.
Abbr.for “Institution of Civil Engineering Surveyors.”
(IEEE) A professional organization of electrical engineers having its headquarters in Piscataway,NJ 08855.
(IEE) A professional organization of electrical,electronic,and systems engineers having its head quarters at Savoy Place,London WC2R OBL.

Abbr. for “insulate” or “insulation.”
1.In Roman town planning,a block of buildings surrounded by streets.2.A Roman apartment house occupying such a block.
A coupling used in metal pipes to interrupt the electrical transmission path that would otherwise exist.
See board insulation.
1.A combination of hydraulic-setting cement (or other bonding ingredient) and a loose-fill insulation,mixed to a workable putty-like consistency;used in insulation applications to fill voids,joints,etc.2.A mixture of dry granular,fibrous,flaky,or powdery materials that develops a plastic consistency when mixed with water,and when dried in place;forms a coherent covering that provides substantial resistance to heat transmission.
Concrete having low thermal conductivity;used as thermal insulation.
Fibrous insulating material (such as wood,cane,or other vegetable fibers) and binder,formed into a board.Manufactured units vary widely in thickness,linear dimensions,density,thermal resistance,and mechanical strength.
Insulation board used as a permanent form for poured-in-place gypsum or lightweight concrete roof decks.
Two sheets of glass that are assembled and sealed around their edges as a single unit;the space between the glass sheets is dehydrated or filled with a gas.Such a unit is effective in reducing the transfer of heat through it.
A panel of double glazing which is sealed around its periphery;provides increased resistance against the transmission of heat and sound.
See electrical insulation,thermal insulation.
A type of oil used within the enclosure of a transformer,switch,or other electric device,for insulating and cooling purposes.
See foil-backed gypsum board.
An expansion strip.
A varnish used as insulator on wire or electric circuits.
See electrical insulation,sound insulation,thermal insulation.
See board insulation.
Gypsum lath having an aluminum foil laminated to its back in order to provide a vapor barrier and reflective insulation against thermal losses.
The resistance to the flow of current through an insulating material resulting from an impressed direct voltage;usually expressed in ohms.
A test to determine the resistance of electrical insulation to the flow of direct current.
