Air Barrier Paper

• A polyolefin sheet material that is permeable to water vapor but not to air or liquid water.

• Air barriers protect the structure from weather to ensure that the interior walls do not become mildewed and corroded. Also they help to reduce energy used by limiting airflow.

Attic Ventilation1. Soffit Vents

located at the eave of a roof, permit generous airflow to the rafter space as they act as the intake to the attic’s ventilation.

Attic Ventilation2. Ridge Vent

Ridge Vents, located at the highest point of a roof, allows air to be exhausted while still protecting the attic from weather.

Attic Ventilation3. Gable Vent

located high in the wall at opposite ends

of an attic. Gable vents create a cross draft to help ventilate

the attic.

Attic Ventilation4. Roof Turbines

Roof Turbines use wind to expel air out of the attic to ensure the moist air does not settle

in the attic and

begin to mold.

Backhoe• Piece of equipment used in the excavation of a site consisting of a

digging bucket on the end of a two-piece articulated arm. This bucket is thirty inches wide.

Batter Boards• Boards that are set horizontally along the edge of a foundation,

which are used to support strings that outline the foundation.

Front-End Loader

Front-end loaders are used to move a material from one place to another. Unlike the bulldozer, the front-end loader can pick up material in its bucket whereas a bulldozer can only push the material. A front-end loader cannot dig into the ground like a

backhoe can do.

Gypsum Board

Wall board made of layers of fiberboard or paper bonded to a gypsum core

Heat Pump

• Compressor/Condenser

fan moves outdoor air across coils containing refrigerant to change the temperature of

the refrigerant.

• Air Handling Unitconditions and circulates the air

in an air-conditioning unit

Advantage: Has the ability to both heat and coolDisadvantage: Difficult to zone

Insulation1. Batt/Blanket

Most popular type of insulation for wall cavities. Also used in some attics, roofs, and floors.

Insulation2. Loose Fill

Most commonly used in attics because it is inexpensive and leaves few voids with no gaps between pieces.

Insulation4. Rigid Board

Used where high R-value per unit thickness is necessary. Commonly found in roof assemblies, walls and ceilings where insulation thickness

is limited, and in below grade areas with a special water resistant composition.

Lintel

A beam that carries the load of a wall across a window or door opening.

Oriented Strand Board (OSB)

A non-veneered building panel composed of long shreds of wood fiber oriented in specific directions and bonded together under pressure. The strands of rectangular wood strips are held together by a wax and resin adhesive.

Plumbing Roof Vent

The Vent Through Roof (VTR) maintains a system of plumbing drains and waste lines at atmospheric pressure by connecting them to the outdoor air.

Plumbing Sink

Drop-In Sink

Plywood

A wood panel composed of an odd number of layers of wood veneer and bonded together under pressure.Veneer – A thin layer, sheet or facing.

Radiant Barrier

Placed adjacent to an airspace in roof or wall assemblies as a deterrent to the passage of infrared energy.

Rebar#5 Rebar, 5/8”

Deformations in rebar are to help prevent slipping

Steep Roof DrainageGutter

a narrow channel which collects rainwater from the roof of a building and diverts it away from the structure, typically into a drain. The main purpose of a rain gutter is to protect a building‘s foundation by channeling water away from its base

Steep Roof DrainageDownspout

Feeds the water collected by the rain gutter

Steep Roof DrainageSplashblock

Used in order to prevent soil erosion/moisture problems around the foundation of a building or house. Leads the water away from foundation
