Front End Loader<br />Primarily used to load material (asphalt, demolition debris, dirt, feed, gravel, logs, raw minerals, recycled material, rock, sand, wood chips, etc.) into or onto another type of machinery.<br /> Differs from a backhoe and bulldozer by only being able to “scoop” material into its bucket and dump it in another location, not dig holes or scrape off land.<br />
Gypsum Board<br />An interior facing panel consisting of a gypsum core sandwiched between paper faces. <br />Drywall, Sheetrock, Plasterboard<br />
Heat Pump<br />Advantage – Heats house efficiently <br />Disadvantage - Difficult to zone because the furnace supplies air to the supply ducts at a single temperature <br />Compressor/ Condenser<br />- Forces air into the supply duct to move over a heating or cooling coil<br />Air Handling Unit<br />- Cleans and dehumidifies internal air and redistributes the air into the house<br />

Plywood<br />Layers of chipped wood are glued together, each with its grain at right angles to adjacent layers for greater strength. There are usually an odd number of plies, as the symmetry makes the board less prone to warping, and the grain on the outside surfaces runs in the same direction. The plies are bonded under heat and pressure.<br />Veneer- A thin layer of wood or other material for facing or inlaying wood.<br />
