Front End Loader• is a heavy equipment machine

(often used in construction) that is primarily used to "load" material into or onto another type of machinery

Gypsum Board• Gypsum Board-

constructing interior walls and ceilings using panels made of gypsum plaster pressed between two thick sheets of paper, then kiln dried.

Heat Pump• Advantage: can change

conditions rapidly and also control humidity

• Disadvantage: they are noisy and difficult to zone

• Compressor/Condenser- the exterior unit of heat pump. A fan pulls air across a line of refrigerant and changes temperature. This adds heat for the winter and is reversed in the summer to let heat out

• Air Handling Unit- moves and conditions air through duct work. A fan sucks in new and return air and re-circulates it

Insulation• Insulation: A material

that has a low thermal conductivity. Used to reduce heat flow in a building. Keeps building warm in the winter and cool in the summer.

Insulation (Cont’d) Foamed

Rigid Board

Lintel• Lintel: A beam that

carries the load of a wall over the opening such as a door or window

panel composed of an odd number of layers of wood veneer bound together under pressure

• Veneer: a thin layer, sheet, or facing. Made from slicing thin pieces from a tree

Radiant Barrier• Radiant Barrier: a

reflective foil placed adjacent to an airspace in roof or wall assemblies as a deterrent to the passage of infrared energy

• This barrier reduces heating and cooling costs.

Rebar• The rebar shown is #4
