Insulation Batts |
This diagram shows the most important areas of the home to insulate for energy efficiency. In
new construction, sidewalls are readily accessible. For older homes; installing additional insulation
in the attic, in floors, over basements and crawl spaces, and in the garage can pay dividends - because
heat loss and heat gain are reduced while installation cost is minimized. |

R-Value |
An R-Value indicates insulating power or thermal resistance. The higher the R-value, the
greater the insulating power. Higher R-values are more effective at maximizing your energy
savings and comfort.
Installing proper amounts of thermally efficient fiber glass insulation is one of the most
cost-effective energy conservation measures that can be taken. |

Unfaced & Kraft-faced Insulation |
Building insulation is a light-density fiber glass blanket used in residential
construction for thermal and acoustical insulation of walls, ceilings and floors.
Unfaced insulation is manufactured in increased widths to permit friction fit installation in wall
cavities. This insulation is used with a separate vapor retarder or where a vapor retarder is not
required. |
|
 |
|
Kraft-faced insulation is manufactured with an integral vapor retarder.  The kraft
facing has formed attachment flanges at the edges which are used for either face or inset
stapling. The kraft facing, applied with asphalt to the fiber glass insulation, has a vapor
transmission (permeance) rating of 1 perm or less. |
