2. Air Barrier – An external membrane applied to the sheathing behind the veneer which serves as a weather barrier and helps prevent air infiltration
3. Attic Ventilation - Serves to allow water vapor and hot attic air to escape through the roof vents and allows for circulation Soffit Vent – Allows air into the attic so that warmer air may escape through the high vents Ridge Vent – Allows hot attic air to escape through the ridge vent Gable Vent – Allows hot attic air to escape and prevents buildup of heat conducted through the roof of the structure Roof Turbine – allows the air to escape by drawing it out through the roof like a fan
4. Backhoe – Heavy machinery used for excavation of smaller site clearing projects such as tree removal or used to dig footing and some basement excavation. Bucket width – 32”
5. Batter Boards – Temporary framework erected just outside the corners of a foundation excavation used to make sure the structure is square and also to carry the lines of a footing from corner to corner
6. Brick Arches Arch with a keystone ELIPTICAL CENTERING!!!!!!!! ROMAN ARCH
9. Bulldozer – Heavy machinery used during site prep. It is used to level a site by grading with the front blade and pushing dirt around areas of the construction site 72” Blade
13. Concrete Joints Isolation Joint – Separates concrete from objects or structures, and allows independent movement without any connection that could cause damage to either object. This one isolates the slab from the driveway. crack Slab Control Joint – a designed cut in concrete to weaken the slab at that point in an attempt to prevent cracking elsewhere Driveway
14. Concrete Masonry unit – block of hardened concrete designed to be laid up like masonry brick. The hollow cores allow for the block walls to be filled with grout for additional strength. CMU is more economical for foundation walls than cast in place concrete, and when laid by a proper mason, one course of block is equal to3 courses of standard brick w/ a 3/8” mortar joint. A typical block is 8” x 8” x 16” w/ a 3/8” mortar joint.
26. Front End Loader – used for transporting piles of dirt or other materials across a jobsite. The hydraulic arms on the bucket allows the ability to place material at a raised elevation. Used for loading dump trucks and backfilling . Unlike a bulldozer, a loader has the ability to scoop dirt out of the ground and move it to another location rather than pushing and spreading it around an area. 72” bucket
27. Gypsum Board – an interior finish board made from a gypsum core sandwiched between two paper faces
28. Heat Pump Compressor – compresses the refrigerant gas which gives off heat, thus cooling the air as it blows across the cooler coils at the air handler -One main disadvantage of the heat pump system is that it is noisy. One must take into account where to place the outside compressors to avoid noise intrusion into the home. -One advantage of a heat pump system is that it is the most efficient way to heat and cool a home
29. Heat Pump Air Handler – forces the air through the system with the use of a blower fan. Also, cooler air is blown across a heating element inside the air handler to warm it up before distributing it through the duct
30. Insulation Batt Insulation – Insulation is used to create the thermal envelope for the house to reduce air infiltration/heat loss in the home
44. Plywood– manufactured by gluing thin layers of wood together, rotating each layer 90 degrees so that the grain in the wood does not run the same direction in each layer. This provides greater strength and equalizes moisture movement ve·neer (və-nîr')n. A 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. A decorative facing, as of brick. A deceptive, superficial show; a façade: a veneer of friendliness.
45. Rebar #4 Rebar (1/2” thickness) The purpose of the deformations is where the concrete will bond to it better
46. Steep Roof Draining Gutter – a channel which collects rainwater at the eave of a roof Downspout – A vertical pipe for conducting the rainwater from the gutter to a lower level discharge point
47. Splashblock - a precast concrete block used to dissipate the water at the downspout’s discharge point Steep Roof Draining
48. Steep Roof Materials Underlayment – A thin layer of waterproof material laid between the roof deck and roofing. It allows to get the house ‘in the dry’ so progress will not be held up due to inclement weather and protects the building before the roofing is applied
57. Steep Roof Terms Ridge - the level intersection of roof planes Valley – the sloping intersection of roof planes when water runs to it Eave – the level, low edge of the roof
59. Steep Roof Terms Soffit – the exposed vertical face of the eave Facia Soffit Facia – the undersurface of a roof overhang installed to enclose the rafter tails
64. Vapor Retarder - put in place to reduce the passage of air and water vapor through the building assembly to prevent condensation. It is usually placed towards the inside of the building (warm-in-winter).
65. Waterproofing – installed to prevent the passage of water through the CMU into a basement or crawlspace. This is an example of liquid applied.
66. Weep Hole - a small hole opening in the brick veneer to allow accumulated water from the building to escape from the cavity wall
