Effective Spray Foam Insulation

Spray foam insulation from Illinois Valley Insulation can solve a lot of your heating and cooling problems. Our polyurethane plastic is sprayed into spaces in your home to create a sealing barrier in walls, roofs, and other surfaces where you lose heat in the winter and cool in the summer.
Closed-cell insulation

Get Top-of-the-Line Closed-Cell Insulation

One of our principal products is closed-cell spray foam, which creates an air barrier with 2.5 inches of foam that covers all the cracks, nooks, and crannies in your home. 

You'll get a superior insulation value that will not only control temperature loss but will increase the stability of your home, reduce the potential for mold, and even deter infestation by insects and rodents!

Consider the Pluses of Closed-Cell Applications

One of the most obvious benefits of sprayed insulation is that it goes just about anywhere and conforms to your structure's contours. You won't have to worry about batts that don't stay in place, leaks around plumbing and electrical fixtures, and fiberglass deterioration.
New Other benefits are less obvious but still important.
  • Reduced air leakage because the foam cells are closed
  • Up to 40% reduction in heating and cooling costs
  • Almost non-existent off-gassing because the ingredients are inert
