Real Estate Glossary
Our glossary is the largest dictionary of real estate and construction terms on the Internet with almost 10,000 definitions.
- Theodolite
- A surveying tool used in precision work.
- Therm
- Measurement unit of heat equal to 100,000 Btu.
- Thermal
- Relating to heat.
- Thermal Coefficient of Expansion
- A factor specifying the expansion and contraction of a material as temperature rises and falls.
- Thermal Conductor
- A material that allows heat to flow through it
- Thermal Insulator
- A material that resists the passage of heat.
- Thermal Mass
- A substance of sufficient density to absorb heat, often used in passive solar heating systems.
- Thermal Spraying
- An industrial process where metal is melted and sprayed onto a surface to form a coating.
- Thermocouple
- A thick copper wire with a sensor on the end, which cools and prevents the flow of gas to the burner if the pilot light goes out.
- Thermoelectricity
- Electricity produced by heating two different metals that are touching.
- Thermometer
- A device for measuring temperature.
- Thermometer, Dry Bulb
- Instrument which measure the amount of heat in the air by the expansion f a liquid in a graduated glass tube with a reservoir bulb at one end. Alternately, by use of a bimetallic strip which moves the indicator on a scale when heat causes the two metals to expand at different rates. Normally used for outdoor temperatures.
- Thermoplastic
- A type of plastic, hard when cool, that is easily softened by applying heat.
- Thermoplastic-insulated Wire
- Electrical wire with a thermoplastic covering. Designated as type T wire.
- Thermosetting Plastic
- Material that can be softened a single time by heat. After one heat application, the substance becomes a heat resistant material.
- Thermosetting Resin
- Material that can be softened a single time by heat. After one heat application, the substance becomes a heat resistant material.
- Thermosiphon Effect
- Movement of fluid induced by heating. The fluid expands as it is heated and is forced through the system.
- Thermostat
- A switch using a bimetallic strip that reacts to changes in temperature. Thermostats are used to regulate heating and cooling systems by switching the heating/cooling on or off as temperature changes.
- Thermowelding
- The connection of plastic fittings by melting at the joints.
- Thermostatic Control
- Device used to regulate the point at which the burner for the water heater is activated.
- Thickened-end Slab
- A concrete slab that is thicker at the perimeter to support the walls of the structure.
- Thickness Gauge
- Also called a feeler gauge, this series of precision thickness, metal blades is used for measuring small gaps, with each blade being marked with the thickness in thousandths of an inch.
- Thin Market
- Market in which there are comparatively few bids to buy or offers to sell real estate. The term relates to a single investment or to a particular investment market, such as the real estate market. In a thin market, buying or selling a few homes can impact disproportionately. Price volatility is generally wider than liquid markets.
- T-Hinge
- A hinge shaped like a T, typically used for decorative purposes in period houses.
- Thinner
- A petroleum-based solvent used for thinning and removing oil-based paint.
- Third Party
- One who is not directly involved in a transaction or contract but may be involved or affected by it.
- Third-Party Origination
- Transaction where the lender has another institution originate all or part of a mortgage.
- Thread Gauge
- A gauge used form checking the accuracy of a threaded component.
- Threads
- Spiral grooves cut into a fastener or component to facilitate connection with other grooved items. Nuts and bolts are examples of threaded fasteners.
- Three-corner File
- A file with a triangular blade, used for work in inaccessible spots.
- Three-prong Plug
- An electrical plug with two flat prongs and one round one (used as a ground). Typically used with high current devices such as refrigerators.
- Three-way Switch
- Switch device, which uses two switches to allow an outlet or light to be activated from either switch.
- Three-way Valve
- A valve with a single inlet and two outlets. The valve can be set so that either outlet is open.
- Three-wire System
- An electrical system using two hot leads and one ground. Typically used for 240-volt service.
- Threshold
-
- The entrance to a building or room.
- A wood or metal strip over an exterior door sill.
- A limit.
- Threshold Limit Value
- Levels of airborne concentrations of chemicals, used to determine safety limits.
- Thrift Institution
- Depository institution, such as mutual savings banks. If organized as mutual associations, depositors are shareholders. They provide mortgages.
- Throat
- A constriction in a passage.
- Through Drying
- Total drying of a painted surface.
- Throw
- The extent of an area illuminated by a given light fixture.
- Thrust
- The application of force in one direction.
- Thrust Block
- Concrete reinforcement poured under a pipe where a direction change occurs. The block supports the pipe and prevents it from moving under the force of the moving liquid inside.
- Thumb Screw
- A screw with a large head, designed to be tightened by hand.
