  • 1. Visual Dictionary BSCI 2300 November 30, 2009
  • 2. Air Barrier Paper Air Barrier Paper – an external membrane applied to the sheathing below the veneer which serves as a weather barrier and helps to prevent air infiltration into the home.
  • 3. Attic Ventilation – Serves to allow water vapor to escape and to allow the hot attic air to escape by providing an intake at the eaves through the soffit vents which allows the warmer air to escape through the roof vents. Attic Ventilation
  • 4. Attic Ventilation Gable Vent – Allows hotter attic air to escape and prevents buildup of heat conducted through the roof of the structure
  • 5. Attic Ventilation Ridge Vent – Allows hot attic air to escape through a gap in the ridge decking
  • 6. Attic Ventilation Roof Turbine – allows the air to escape by drawing it out through the roof like a fan
  • 7. Attic Ventilation Soffit Vent – Allows air into the attic so that the warmer air can be pushed out through the vents placed higher on the roof
  • 8. Backhoe – Heavy machinery used for excavation in smaller site clearing projects like tree removal and used to dig footings and some basement excavation. 2’ wide bucket Backhoe

  • 21. Brick Sizes Queen Size 3” w x 2 ¾” h x 7 5/8” l
  • 22. Bulldozer Bulldozer – heavy machinery used during site prep. It is used to level the dirt off by grading with the front blade and pushing dirt around small areas of the construction site.
  • 23. Cladding Brick Clad & Stone Clad – coursed rubble
  • 24. Cladding Wood Board Clad
  • 25. Cladding EIFS
  • 26. Cladding Wood Shake – small shingle split from a block of wood, which gives a rough texture and uneven depths Wood Shingle – sawn shingle, typically more smooth and uniform; also larger in size
  • 27. Code Requirements Windows : minimum opening of 5.7 square feet (5.0 if sill is less than 44” AFF) Opening width 20” minimum & opening height 24” minimum. Actual Measurements – 26” h x 32” w x 36” AFF. Total Area : 5.78 sq. ft. The window meets the code requirements
  • 28. Code Requirements Code requirements – Riser Height 7 ¾” maximum Tread Depth 10” nosing to nosing Actual measurements – Riser Height of 7 5/8 tread depth 11 5/8” (less 1 ½ “ overhang) gives 10 1/8”. Therefore, the stair is in compliance with the code.
  • 29. Construction Joints Isolation joints - separate concrete from objects or structures, and allow independent movement without any connection that could cause damage to either object.
  • 30. Concrete Joints Control Joint – a designed cut in concrete to weaken the slab at that point in an attempt to prevent cracking elsewhere in the concrete
  • 31. Concrete Masonry Unit CMU – a block of hardened concrete designed to be laid up like regular masonry brick. The hollow cores allow for the block walls to be filled with concrete for additional strength. CMU is more economical for foundation walls than cast concrete, and when laid by a proper mason, one course of block is equal to 3 courses of standard brick w/ a 3/8” mortar joint. A typical block is 8” x 8” x 16” with a 3/8” mortar joint. The photo at left shows a poor job w/ a joint less than ¼”.
  • 32. Decorative CMU Split Block
  • 33. Decorative CMU Ribbed Block
  • 34. Doors Flush Door
  • 35. Doors Top Rail Style Panel Lock Rail Transom Sidelight Bottom Rail Transom – A small window directly over a door Sidelight – A tall, narrow widow running alongside a door
  • 36. Electrical Components Underground Transformer Box – Steps down the electricity from a few thousand volts to the 110v / 220v service needed for the home
  • 37. Electrical Components Service Head – Brings the electricity into the meter and isolates that particular residence through an in-line fuse which prevents the house wiring from interfering with other structures on the grid Meter – Measures how much electricity is being used
  • 38. Electrical Components Service Panel – the point where the electricity enters the home. The panel distributes the electricity throughout the home through individual circuits.
  • 39. Electrical Components Duplex Receptacle – where the power is accessed in the home
  • 40. Subfloor #8 Ceiling joist #7 Top Plate #6 Stud #5 Sole Plate Framing Elements
  • 41. Framing Elements # 10 Roof Decking #9 Rafter
  • 42. Farming Elements #11 Sheathing
  • 43. Framing Elements #12 Stringer
  • 44. Front End Loader Front End Loader – used for transporting piles of dirt or other material across a jobsite. The hydraulic arms on the bucket allows the ability to place material at a raised elevation – useful for loading dump trucks and backfilling retaining walls. Unlike a bulldozer, a loader has the ability to scoop dirt out of the ground and move it to another location rather than spreading it around an area
  • 45. Gypsum Board Gypsum Board – An interior finish board made from a gypsum core sandwiched between two paper faces.
  • 46. Compressor – compresses the refrigerant gas which gives off heat, thus cooling the air as it blows across the cooler coils at the air handler Heat Pump 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.
  • 47. 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 ductwork One advantage of heat pump systems is that it is the most efficient way to heat and cool a home
  • 48. Insulation Batt Insulation Insulation is used to create the thermal envelope for the house to reduce air infiltration/ heat loss in the home
