Insulating an attic properly is one of the most significant conservation measures you can make. An under-insulated attic provides an easy escape route for heated air and can cost you hundreds of dollars in wasted fuel in a single winter.


Follow these tips to ensure that your home is properly insulated and is not "leaking money":

  • Air-seal your attic before you insulate.
  • Make sure that your home has sufficient insulation in the walls, ceilings and floors. For homes in Virginia, the federal Energy Star® program recommends R38 to R60 insulation in ceilings, R38 in walls, and R25 to R30 under floors.
  • Use higher density insulation, such as rigid foam boards, in cathedral ceilings and on exterior walls.
  • Install attic vents to control moisture and keep the attic cooler in the hot months.
  • Do not place insulation over the top of recessed light fixtures unless they are marked IC, which means they are designed for direct insulation contact.
  • Do not over-pack insulation in any tight spaces. It insulates most effectively when not compacted.
  • If you use blown-in insulation in your attic, use baffles to prevent blockage of air vents that provide vital air circulation.
  • If you use blown-in insulation in your attic, make sure it is evenly distributed, with no low spots.
  • Be sure to insulate and weather-strip the door or panel covering the attic opening.
  • Consider insulating other important areas, such as walls and floors over unheated spaces. You can also install new doors and windows that improve insulation.
