Air Barrier Paper

• Definition-A material used as both a vapor retarded and an air barrier

• It is keeping the sheathing dry and unharmed from weather conditions, any water that penetrates is allowed to be released as water vapor

Attic Ventilation-Soffit Vent

Front End Loader

• A front end loader differs from a backhoe because a backhoe is used for primarily digging, not picking up and moving materials. A front end loader differs from a bulldozer because it is used to pick up dirt and materials instead of pushing the dirt or materials.

Gypsum Board

• Definition- wallboard with a gypsum plaster core bonded to layers of paper or fiberboard; used instead of plaster or wallboard to make interior walls

Heat Pump-Compressor/Condensor• Advantage of Heat

Pumps- Heat pumps often pay for themselves in only a few month from the energy that they save

• Disadvantage of Heat Pumps- Inability to work at very low temperatures

Heat Pump-Air Handling Unit

• Air Handling Unit- A device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system

Insulation- Batt or Blanket

• Batt and blanket insulation is made of mineral fiber -- either processed fiberglass or rock wool -- and is used to insulate below floors, above ceilings, and within walls. Generally, batt insulation is the least expensive wall insulation material but requires careful installation for effective performance.

Insulation-Loose Fill Insulation

• Loose-fill insulation includes loose fibers or fiber pellets that are blown into building cavities or attics using special equipment. It generally costs more than batt insulation. However, it usually fills nooks and crannies easier, reduces air leakage better, and provides better sound insulation than batt-type insulation.

Insulation-Foam Insulation

• Spray foam insulation is a two-part liquid containing a polymer (such as polyurethane or modified urethane) and a foaming agent. The liquid is sprayed through a nozzle into wall, ceiling, and floor cavities. As it is applied it expands into a solid cellular plastic with millions of tiny air-filled cells that fill every nook and cranny. Spray foam insulation should be applied by a professional using special equipment to meter, mix, and spray into place. Spray foam insulation is commonly used for retrofits; it is good for irregularly shaped areas and around obstructions

Insulation-Rigid Board Insulation

• Rigid board insulation is commonly made from fiberglass, polystyrene, or polyurethane and comes in a variety of thicknesses with a high insulating value (approximately R-4 to R-8 per inch). This type of insulation is used for reproofing work on flat roofs, on basement walls and as perimeter insulation at concrete slab edges, and in cathedral ceilings.
