Definition of Poly-Wrap

Poly-Wrap

polyethylene wrap that encloses Owens Corning MIRAFLEX® insulation, making it comfortable to touch, less likely to itch and irritate, and easier to handle and install. The poly wrap has tiny perforations that allow the insulation to breathe and resist the collection of moisture within the wrap.

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.

Foil-Faced Vapor Retarder

Created by coating a foil-backed paper with a thin layer of asphalt adhesive. The coated side of the foil-backed paper is then applied to the un-faced insulation material. The asphalt adhesive bonds the foil-backed paper and the insulation together.

Kraft-Faced Vapor Retarder

Created by coating kraft paper with a thin layer of asphalt adhesive. The coated side of the kraft paper is then applied to the unfaced insulation material. The asphalt adhesive bonds the kraft paper and the insulation together.

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 Barrier System

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

Vapor Retarder

Helps control the amount of moisture passing through the insulation and collecting inside exterior walls, ceilings and floors.

Preferred Rates

As non-smoking rates caused a major reduction in the cost of life insurance in the early 1980's, the emergence of preferred non-smoker rates in 1998 has caused another noteworthy reduction in rates. A growing number of insurance companies are offering better rates which go beyond simply looking at gender or smoking habits. Other health related factors such as physical build, lifestyle, avocation and personal and family health history indicating longer life expectancy can add up to significant cost savings to new life insurance applicants. Make certain to ask about these new preferred rates.

Preferred Beneficiary

used in older contracts to confer the same rights as an irrevocable beneficiary. Applied to family members.

Agreement of Purchase and Sale

A legal agreement that offers a certain price for a home. The offer may be firm (no conditions attached), or conditional (certain conditions must be fulfilled before the deal can be closed).

Single-family home

A detached house.

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.

Construction Documents

All drawings, specifications and addenda associated with a specific construction project.

Faced Insulation

insulation with an attached vapor retarder (kraft paper or foil-backed paper).

Fiber Glass Insulation

An energy-efficient glass fiber product manufactured by Owens Corning to ensure the best thermal and noise control performance available.

Insulation Density

Denser insulation products have more fibers per square inch and, therefore, give you greater insulating power through higher R-values.

Metal Insulation Support

16" or 24" wire rod or crisscrossed wire to hold floor insulation in place.

MIRAFLEX® Fiber

A revolutionary soft-to-the-touch glass fiber insulation developed by Owens Corning for easier handling and installation. In addition to its virtually itch-free characteristic, insulation with MIRAFLEX® has extraordinary resiliency allowing it to be packaged in more convenient, ultra-compact rolls.

Pitch

The angle of slope of a roof.

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.

Un-faced Insulation

insulation with no attached vapor retarder.

Walk Through

A final inspection of a home before "closing" to look for and document problems that need to be corrected.
