Attic Insulation

Having Enough Insulation is Important.

Over a 5 year span, attic insulation can settle as much as 20%, significantly reducing the insulation performance.  A rule of thumb is if you can see the joists in your attic, you do not have adequate insulation.  An attic that is not properly insulated can significantly increase you cooling and heating costs. 

How can we help?
The first step, is to schedule a Home Performance Evaluation. The evaluation will include a thorough inspection of your home (Attic, Basement and Conditioned areas) to detect areas of air loss, and inadequate insulation. Your Home Performance Advisors will use a smoke pencil and thermal imaging camera to help identify leaks in your attic, around doors, windows, ceiling lights, outlets, ducts, and other areas in your home.The advisor will also walk you through your home to point out areas where you can improve its energy efficiency. Having an evaluation performed is the first step to creating a plan that will save you money on your utility bills and create a more comfortable home.

How do I know if my home has enough insulation and is properly sealed?

Most homes, even newer homes, lack adequate insulation and have areas where air is constantly leaking out of their homes.  If you live in a split level home, these are notorious for air leaks and inadequate insulation. According to the U.S. Department of Energy, most of the money that you spend to heat and cool your home is disappearing through cracks and holes in your ceiling, walls, and floors.

  • 31% through floors, walls, and ceilings
  • 15% through your duct work
  • 13% through plumbing penetrations
  • 11% through doors
  • 10% through windows

How much insulation do I need? 

  • 16 to 18" - Insulation performance is measured by R-value, its ability to resist heat flow. Higher R-values mean more insulating power.  R-49 is the recommended level of insulation for homes located in the Midwest. That is about 18 inches of insulation (most homes only have around 6 inches of insulation). 

Why air sealing is as important as insulation.

  • Insulation works best when air is not moving through or around it. So it is very important to seal air leaks before installing insulation to ensure that you get the best performance and to make certain that your heating and cooling systems operate efficiently.
