What is Topping Off Insulation?

Topping off insulation means adding additional insulation material over your existing attic insulation to increase its R-value and improve energy efficiency. This is typically done when your current insulation has settled, deteriorated, or simply isn't thick enough to meet current energy standards.

Cost-Effective Solution

More affordable than complete insulation replacement while delivering significant energy savings.

Quick Installation

Typically completed in just a few hours for most residential attics.

Immediate Benefits

Start saving on energy bills immediately after installation. Improved indoor temperature  

When Should You Consider Topping Off?

  • Your insulation is less than 10-12 inches deep
  • Energy bills have increased significantly
  • Rooms feel drafty or temperature varies greatly
  • Your home was built before 1980
