Insulation Installation for Homes in the Long Island Area

Two of the most important areas of a home to insulate are the attic and the interior and exterior walls.


As one of the biggest sources of energy loss in your home, the attic needs to be insulated. Whether it’s unfinished or used as extra living space, it holds a lot of potential for energy savings. Fiberglass, cellulose, spray foam and radiant barrier can be used for attic insulation.

According to the U.S. Department of Energy, the attic should be thoroughly insulated:

  • Between and over the floor joists in unfinished attics (so the living space below is sealed off)
  • In access door
  • Between knee wall studs
  • Between the studs and rafters of exterior walls and roof
  • In ceilings with cold spaces above

Loose-fill or batt insulation is typically installed in an attic, but other materials can work too. In warm climates, radiant barriers are good solutions as well.

The right amount of exterior and interior wall insulation can help improve year-round energy efficiency and comfort. According to the Department of Energy, all exterior walls should be insulated, including walls between living spaces and unconditioned spaces (such as garages and storage areas), foundation walls above ground level and foundation walls in heated basements.

If your attic has enough insulation and proper air sealing, and your home still feels uncomfortable (too cold in the winter and too hot in the summer), or you’re experiencing drafts, there’s a good chance you need to add insulation to the exterior walls.

Installing blown-in insulation using the dense pack technique can provide significant air sealing. This type of insulation can also be added to exterior walls without much disturbance to finished areas of the home.
