For fiberglass batting insulation we use American Made insulation from CertainTeed.  This is a top of the line insulation that will insure the proper application to keep your home cool in the summer and warm in the winter.  A detailed description is below.

Energy Efficiency Plain & Simple

Installing Fiber Glass Building Insulation is an easy, cost effective method to help conserve energy in residential and commercial new construction, remodeling, and reinsulation. In addition to its thermal properties, Fiber Glass Building Insulation also provides excellent acoustical performance. It is compression packaged for ease of handling, and its broad availability of R-values, sizes and facings ensures the right product for the job.


  • A high-quality fiber glass batt or roll 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, such as CertainTeed’s MemBrain™, The Smart Vapor Retarder, or where a vapor retarder is not required.
  • Kraft Faced insulation is manufactured with an integral vapor retarder. The kraft facing includes attachment flanges at the edges that 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 one perm or less.


  • Thermally efficient to help fight rising utility bills
  • Lightweight and flexible for easy installation
  • Good sound absorption; reduces noise level wherever applied
  • Inorganic glass fiber is noncorrosive; it will not rot or mildew or otherwise deteriorate
  • Does not absorb moisture
  • Noncombustible per ASTM E136 (unfaced only)
