Attic Insulation

The North American Insulation Manufacturers Association states that approximately 65% of U.S. homes lack proper levels of insulation

What is Attic Insulation?

Attic insulation comes in various forms including batts, rolls, loose-fill and rigid foam boards. Each type is manufactured differently and made for different uses within a home. The amount of insulation required is based on the Department of Energy’s predetermined zones which can be found on the bottom of this page. The Freeman Company strongly advocates the proper use of insulation to properly make your home energy efficient.

Why proper levels of attic insulation important?

Having the correct levels of insulation can have many benefits including:

• Reduction of pollutants like sulfur oxide, nitrous oxide and fine particle matter.
• Increased health benefits, i.e. respiratory and cardiovascular aliments associated with air pollution and premature deaths.
• Reduction in energy usage and emissions
