Definition of Faced Insulation

Faced Insulation

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

Un-faced Insulation

insulation with no attached vapor retarder.

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.

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.

Stapling Flange

A protruding edge on faced insulation used to staple the insulation to the framing.

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.

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.
