2. The air barrier paper is a wrap (green in the picture above) that completely covers the exterior walls of a building and aids in retarding wind and water, yet still permits the passage of water vapor that accumulates inside the wall.
3. The soffit vent shown above is a way to vent excess heat from the attic space. Soffit Vent

47. Lavatory Standard drain piping is 1-1/2” Water Closet Standard drain piping is 3” Manufactured Tub in Framing
48. Plumbing Vent Through Roof The VTR is depressurizing the waste piping of the indoor plumbing, thereby preventing the passage of sewer gas into the home. Kitchen Drop-in Sink
49. Plywood is an engineered wood product in which layers of wood are heated and compressed at right angles to each other to increase the strength of the board and reduce warping. Plywood comes in a variety of veneers. A veneer is covering over another surface that usually enhances the aesthetic appeal of the surface. Perpendicular Layers
50. The purpose of the deformations in the rebar is to create more surface area for the steel rebar to adhere to the concrete into which the rebar is set. The rebar photographed above is ½” in diameter. It is #4 rebar.
51. Gutter Downspout Splashblock A gutter is a metal or plastic tubing attached to the eaves of a building designed to collect rainwater from the roof. The gutter is sloped down slightly to allow the water to flow towards the downspout. The downspout is a metal or plastic tube connected to the gutter. It collects the rainwater from the gutter and directs it neatly to the ground. The splashblock is a concrete block located on the ground that helps to prevent the erosion of the soil caused by water exiting the downspout.
52. Underlayment The underlayment is normally a tar paper used to enhance the water and air resistance of the roof. Clay Tile Roof
53. Wood Shingle Roof Shingles are a roof covering that is neatly cut on its edges to increase uniformity. They are laid from the eave to the ridge in order to allow rainwater to drain.
54. Metal Pane Roof Galvanized Steel is typically used for Metal Pane Roofing because the zinc coat helps prevent corrosion of the steel.
57. Ridge Eave Valley Rake A ridge is the horizontal plane where the rafters meet. A valley is a depression in the roof caused by two angled sides joining along a plane. A rake is the a board placed along the sloping sides of a gable. An eave is the lowest overhanging edge of a roof and is imaginary in the sense that no material celebrates it’s exact location.
58. Fascia Soffit The soffit is the underneath side of the overhang of the roof. The fascia is the board that runs horizontally at the end of the roof overhang that sometimes hides the ends of the rafters.
59. Building without a fascia board A building without a fascia does not have a board or any material running horizontally at the end of the roof overhang.
62. The vapor retarder helps to reduce the ability of moisture to pass into a building. To accomplish this task, it is placed on the “warm in winter” side of the insulation. In the photograph above, the vapor retarder is the brown wrapping around the batt insulation in an attic.
63. Waterproofing aids concrete, which is not naturally water-resistant, in preventing the passage of water and moisture into a building from underneath. The white color under the welded wire fabric (shown above) is a loosely applied waterproofing.
64. Weep holes are gaps in a masonry wall or veneer that allow water that has permeated the masonwork to drain to the exterior of the wall, preventing the decay and deterioration of the structural wall.
66. The widow photographed above is a single hung window because only one sash (bottom) is vertically movable. Single Hung Window
67. The window photographed above is an outswinging casement window because it is hinged on one side like a door and opens outward via a crank handle. Casement Window
68. Hopper Window The window photographed above is a hopper window because it is hinged on the bottom and opens inwards.
