Typical Homes Lose Up To:

10% through windows

15% through doors 15% through foundation

25% through the roof

35% through un-insulated walls!

Nearly 25% of your home’s wall is made up of studs that typically are not insulated, so it’s like having one entire wall of your home with no insulation. Adding insulation to your home’s exterior under new siding can help your home meet U.S. Department of Energy (DOE) insulation recommendations, as well as state and local codes.

ProFold® Goes Beyond Energy Savings

• Levels the wall under new siding, providing a consistent, stable base for siding to be installed smooth and straight.

• Deters termite infestation with a built-in termite control agent.

• Protected by a Lifetime Transferrable product warranty, one of the strongest in the industry, covering r-value retention, moisture absorption, and structural integrity
