Front End Loader<br />Front End Loader- A machine that is primarily used to load material into or onto another type of machinery. Differs from a backhoe because it doesn’t excavate dirt and differs from a bulldozer because it doesn’t clear and grade land <br />
Gypsum Board<br />Gypsum Board- Drywall, gypsum board, construction is used globally for the finish construction of interior walls and ceilings. <br />
Heat Pump<br />What its doing: a machine or device that moves heat from one location (the 'source') to another location (the 'sink' or 'heat sink') using mechanical work<br />Advantage: Heat pumps are one of the most efficient systems you can buy to heat your home. It saves energy.<br />Disadvantage: If you live in an area that is frequently below freezing in winter, a back up system may be required to provide enough heat for the entire home<br />Compressor/Condenser<br />What its doing: a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system<br />Air Handling Unit<br />
Rebar<br /><ul><li>This rebar was a #3 with it being 3/8’’.
The purpose of the deformations in this rebar is to connect the slab when poured.</li></li></ul><li>Steep Roof Drainage<br />Downspout: is a pipe attached to the side of a building, through which water flows from the roof into a drain<br />Splash block: directs water away to protect your foundation and soil from damaging rainwater erosion. <br />Gutter: A narrow channel which collects rainwater from the roof of a building and diverts it away from the structure, typically into a drain.<br />
Steep Roof Materials<br />A shingle is flat covering element for a roof consisting of individual overlapping elements. <br />Metal Shingle Roof<br />Clay Tile Roof<br />Underlayment: Roof underlayments are designed to protect the roof sheathing and structure from moisture and penetration<br />What its doing: Roof underlayment performs as a secondary weather resistant barrier under roof cladding. <br />Galvanized Steel Metal Panel Roof<br />Roofing Underlayment<br />
Steep Roof Terms<br />Valley: is formed where two roofs join at an angle<br />Ridge: The uppermost, horizontal external angle formed by the intersection of two sloping roof planes<br />Eave: The projecting overhang at the lower edge of a roof<br />Rake: The inclined edge of a sloped roof over a wall<br />Soffit: The finished underside of the eaves<br />Fascia: A flat horizontal band around a roof's perimeter.<br />Building without a fascia: A building with no horizontal band around a roof's perimeter<br />
Weep Hole<br />Weep Hole: Are small openings left in the outer wall of masonry construction <br />What its doing: It is an outlet for water inside a building to move outside the wall and evaporate.<br />
Windows<br />3. Awning– Awning windows are similar to casement windows but are hinged horizontally<br />2. Double hung -The window consists of two sashes that move up and down<br />1. Sliding – Sliding windows move on top and bottom tracks.<br />
