   stud wall.

» Thermal conductivity The rate at which a material conducts heat.

» Thermal emittance A unitless index, from 0 to 1, expressing a material’s tendency to radiate thermal energy as its temperature rises in relation to surround- ing surfaces.

» Thermal insulation A material that greatly retards the passage of heat. Thermal resistance The resistance of a material or assembly to the conduction of heat.

» Thermochromic glass Glass that chang- es its optical properties in response to changes in temperature.

Thermoplastic In plastics, having the property of softening when heated and rehardening when cooled; weldable by heat or solvents.

» Thermoplastic polyolefin (TPO) A ther- moplastic single-ply roof membrane ma- terial, made from blends of polyethylene, polypropylene, and ethylene-propylene rubber polymers.

» Thermosetting In plastics, not having the property of softening when heated; not heat-fusible.

» Thickset tile Ceramic tile installed on a thick bed of portland cement mortar; also called mortar bed or mud set tile.

» Thin-set tile Ceramic tile bonded to a solid base with a thin application of portland cement mortar or organic adhesive.

» Through-wall flashing See Internal flash- ing.

» Thrust A lateral or inclined force result- ing from the structural action of an arch, vault, dome, suspension structure, or rigid frame.

» Thrust block A wooden block running perpendicular to the stringers at the bot- tom of a stair, whose function is to hold the stringers in place.

» Tie A device for holding two parts of a construction together; a structural device that acts in tension.

» Tieback A tie, one end of which is anchored in the ground, with the other end used to support sheeting around an excavation.

» Tie beam A reinforced concrete beam cast as part of a masonr y wall, whose primar y purpose is to hold the wall together, especially against seismic loads, or cast between a
   number of isolated foundation elements to maintain their relative positions.

   Tier The portion of a multistor y steel building frame supported by one set of fabricated column pieces, commonly two stories in height.

» Tie rod A steel rod that acts in tension. Tile A fired clay product that is thinner in cross section than a brick, either a thin, flat element (ceramic tile or quarr y tile), a thin,
   cur ved element (roofing tile), or a hollow element with thin walls (flue tile, tile pipe, structural clay tile); also a thin, flat element of another material, such as an acoustical
   ceiling unit or a resilient floor unit.

Tilt/turn window A window that opens either by rotating its sash about its vertical centerline or as a hopper.

» Tilt-up construction A method of con- structing concrete walls in which panels are cast and cured flat on a floor slab, then tilted up into their final positions.Timber Standing trees; a large piece of dimension lumber.

» Tinted glass Glass that is colored with pigments, dyes, or other admixtures. Titanium A strong, corrosion-resistant, nonferrous metal, silver gray in color.

» Toe nailing Fastening with nails driven at an angle.

» Tongue and groove An interlocking edge detail for joining planks or panels. Tooling The finishing of a mortar joint or sealant joint by pressing and compact- ing it to create a
   particular profile. Toothed plate A multipronged fastener made from stamped sheet metal, used to join members of a lightwood wood truss.

» Top-hinged inswinging window A win- dow that opens inward on hinges on or near its head.

» Topping A thin layer of concrete cast over the top of a floor deck.

» Topping-out Placing the last member in a building frame.

» Top plate The horizontal member at the top of the studs in a wall in a light frame building.

» Topside vent A water-protected open- ing through a roof membrane to relieve pressure from water vapor that may accu- mulate beneath the membrane.

» Torque Twisting action; moment. Torsional stress Stress resulting from the twisting of a structural member.

» Touch sanded In plywood, lightly sand- ed to produce a smoother, flatter surface. TPO see Thermoplastic polyolefin.

» Tracheids The longitudinal cells in a softwood.

» Traffic deck A walking surface placed on top of a roof membrane.

   whose rotating steel blades are used to finish concrete slabs; to use a trowel.

» Truss A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members. See also Vierendeel truss.

» Tuckpointing Traditionally, a method of finishing masonr y joints using mortars of different colors to artificially create the appearance of a more refined joint; in contemporar y
   usage, may be used inter- changeably with repointing.

» Tunnel kiln A kiln through which clay products are passed on railroad cars.

Turn-of-nut method A method of achiev- ing the correct tightness in a high-strength bolt by first tightening the nut snugly, then turning it a specified additional fraction of a turn.
