Attic Ventilation Important for allowing water vapor and heat to escape the
attic space.
Ridge Vent: a vent placed over the gap where the roof decking meets at the ridge
Attic Ventilation Continued
•Soffit Vent- allows air to come into the bottom of the attic so that the hot air can be pushed through the gable and ridge vents.

Definition:
Boards used during the rough site work and excavation period to create the temporary outline of where the building will be constructed.
Helps ensure the building footings will be square and straight.

Front End Loader•Piece of heavy machinery used for transporting large amounts of soil or dirt from different points on the site or for loading dump trucks for the removal of the dirt from the site.
Gypsum Board•An interior facing panel consisting of a gypsum core between two paper faces. • Usually sanded and painted• Also known as “dry wall”
Heat Pump•Compressor/Evaporator: Compresses gases which gives off heat. The air cools as it blows across the cooling coils in the air handler
•Advantage: Highly efficient in mild climates
•Disadvantage: May need additional heating source in areas with very cold climates. Not used as much up north.
•Air handling unit: forces air through a duct system with a strong fan
InsulationPurpose: to reduce the heat flow through the assembly of a
building
Batt/Blanket- rolls or sheets of insulation easily installed between the studs in walls
Loose Fill- fiberglass insulation blown into place between ceiling joists in attics
InsulationFoamed- a mixture of two chemicals that react to form very affective insulation that also completely fills in cracks.
Rigid Board- comes in 4’X8’ sheets and is used as exterior sheathing for basement walls
