Definition of Radiant Barrier System

Radiant Barrier System

A radiant barrier system (RBS) is a building section that includes a radiant barrier facing an air space.

High Voltage System

See Electricity.

Low-Voltage System

Provides security, entertainment, communications, environmental control, networking, and other functions generally powered by a signal cable, phone line or data cable. Is not typically metered.

Polyethylene Vapor Barrier

Plastic film used to prevent moisture from passing through unfaced insulation. Both 4- and 6-mil polyethylene are preferred because they are less likely to be damaged during construction.

Radiant Barrier

A radiant barrier is a reflective surface, on or near a building component, that intercepts the flow of radiant energy to and from the building component.

Radiant Heat

A heating system which uses hot water, steam pipes or electric resistance coils to heat the floors, walls or the ceilings of a room.

Reflective Insulation System

Reflective Insulation system is formed by a combination of low emittance surfaces and air spaces that provide reflective cavities, which have low levels of radiant energy transmission.

High Ratio Mortgage

If you don't have 20% of the lesser of the purchase price or appraised value of the property, your mortgage must be insured against payment default by a Mortgage Insurer, such as CMHC.

Allowance

A sum of money set aside in the construction contract for items which have not been selected and specified in the construction contract. For example, selection of tile as a flooring may require an allowance for an underlayment material, or an electrical allowance which sets aside an amount of money to be spent on electrical fixtures.

Irrevocable Beneficiary

Legal designation that cannot be contested. (See beneficiary)

Personal Line of credit (Credit Insurance)

A bank's commitment to make loans to a borrower up to a specified maximum during a specific period, usually one year.

Security

In the case of mortgages, real estate offered as collateral for the loan.

Air Space

The area between insulation facing and interior of exterior wall coverings. Normally a 1" air gap.

Building Code

A comprehensive set of laws that controls the construction or remodeling of a home or other structure.

Central Air Conditioning

A System which uses ducts to distribute cooling and/or dehumidified air to more than one room or uses pipes to distribute chilled water to heat exchangers in more than one room, and which is not plugged into an electrical convenience outlet.

Crawlspace Foundation

The space between the ground and the first floor of a home, usually no higher than four feet.

Crawlspace Vent

An opening to allow the passage of air through the unexcavated area under a first floor. Ideally there should be at least two vents per crawlspace.

Electricity

Provides power for lighting, appliances, and heating & cooling in a home. A meter records usage for billing by your local utility.

Forced Air Heating

A common form of heating with natural gas, propane, oil or Electricity as a fuel. air is heated in the furnace and distributed through a set of metal ducts to various areas of the house.

Polyethylene Vapor Barrier

Plastic film used to prevent moisture from passing through unfaced insulation. Both 4- and 6-mil polyethylene are preferred because they are less likely to be damaged during construction.

Radiant Barrier

A radiant barrier is a reflective surface, on or near a building component, that intercepts the flow of radiant energy to and from the building component.

Radiant Heat

A heating System which uses hot water, steam pipes or electric resistance coils to heat the floors, walls or the ceilings of a room.

Red-Lined Prints

Blueprints that reflect changes and that are marked with red pencil.

Reflective Insulation System

Reflective Insulation System is formed by a combination of low emittance surfaces and air spaces that provide reflective cavities, which have low levels of radiant energy transmission.

Zero-lot line

The positioning of a house near or on top of the lot boundary, resulting in little or no space between houses.
