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.



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.
