Be sure that your home has the right amount of insulation to keep your family warm and keep the heating and cooling bills low. In fact, you can save 20% on your heating and cooling bills for years to come by adding the correct amount of insulation. Our experts would be happy to help you find just the right insulation and/or drywall for your project.

How much attic insulation do you need? Experts say that 15.5" inches is ideal for the best insulating value. If you can see wood beams, you need more insulation. We are in Zone 5 for which the Department of Energy suggests an R-value of R49-R60.

DOE Recommends
  • 10-12" existing - get at least one layer R-19

  • No insulation - get at least one layer of R-19 + one of R-30
