2. Air barrier paperA composite sheet material used as a vapor retarder to control air, control water, and permit water vapor
3. Attic Ventilation MaterialsOpening that allows air to flow into the attic or the space bellow the roof sheathing along with the removal of heat through the upper most part of the roof. This helps keep the attic cool in the summer and allows moisture in the attic to evaporate
8. BackhoeAn excavator whose shovel bucket is attached to a hinged boom and is drawn backwards to move earth. Typically used in digging foundation footers. Bucket was 18’’ in width
9. Batter BoardsA temporary frame built just outside the corner of an excavation to carry marks that lie on the surface planes of the basement that will be built in the excavation

30. Code requirementsA set of legal restrictions intended to ensure a minimum standard of health and safety in buildings. These stairs had a rise of 7’’ and a run of 10 ½ which meets code requirements.
36. Concrete JointIsolation Joint- used to relieve flexural stresses due to vertical movement allowing expansion and contraction. The brick wall is isolated from the concrete slab.
37. Concrete masonry unitsA block of hardened concrete, with or without hollow cores, designed to be laid in the same manor as a brick or stone. CMU’s are realatively cheap and limited in design but labor intensive. 8’’
48. Electrical Components4. Service Panel- protects the electrical load of the facility and distributes electricity into individual circuts and branches for fixtures, switches, and outlets.
49. Electrical Components5.Duplex Receptacle- electrical power outlet receiving power from branch circuts typically 110 volts and occasionally 220 volts depending on device.
62. Front end loadera heavy equipment machine (often used in construction) that is primarily used to "load" material (asphalt, demolition debris, dirt, feed, gravel, logs, raw minerals, recycled material, rock, sand, wood chips, etc.
63. Gypsum Boardwallboard with a gypsum plaster core bonded to layers of paper or fiberboard; used instead of plaster or wallboard to make interior wall.
64.
65. Air handling Unit- central unit consisting of a blower, heating and cooling elements, filter racks or chamber, branches off heated or cooled air into trunk and branch ducts Air Handling unit Compressor/Evaporator Advantage- Heat Pump systems have a rapid response time DisAdvantage- It is difficult to zone and may need help in extreme cold
66. InsulationTo surround or separate with nonconducting material in order to prevent or lessen the leakage of electricity, heat, cold, sound, radiation, etc.
71. Lintel A horizontal structural member, such as a beam or stone, that spans an opening, as between the uprights of a door or window or between two columns or piers. Steel Lintel
72. Mortar 1. Concave Mortar Joint- tooled 3/8’’ mortar joint used in residential construction. Type O – medium-low strength mortar
73. Mortar Extruded Mortar Joint- Neither tooled or trialed with with 3/8’’ thickness and type O medium low strength mortar.
74. Oriented strand board A nonveneer panel product also known as OSB, wafer board, Sterling board or Exterior board and Smart Ply , is an engineered wood product formed by layering strands or flakes of wood in specific orientations. In appearance, it may have a rough and variegated surface with the individual strips lying unevenly across each other.
78. Plumbing4. Vent Through Roof (VTR)- release waste gas and supplies air so that draining water cannot create a suction to pull water out of the p-trap
80. Plywood structural material made of layers of wood glued together, usually with the grains of adjoining layers at right angles to each other. Veneer- thin surface layer, as of finely grained wood, glued to a base of inferior material. Any of the thin layers glued together to make plywood
81. Radiant barrier A radiant barrier is used in our area principally as a cooling strategy. Buildings gain heat in three ways – conduction, convection, and radiation. A radiant barrier is useful in preventing heat gain from radiation.
82. Rebar Various lengths of steel reinforcing bars used in concrete or masonry for additional strength, measured in #’s. This is ½ ‘’ rebar referred to as a # 4 bar. The deformations on the rebar help it t bond tightly to conrete.
83. Steep Roof Drainage 1. Gutter- a channel that collects rainwater and snow melt at the eave of a roof.
84. Steep Roof Drainage 2. Downspout- connected to the gutter to transport water down to ground level.
85. Steep Roof Drainage 3. Splashblock- vertical flashing installed at the bottom of steep drainage situations to block and divert water into the ground.
