ProBoard Insulating Sheathing

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.

ProBoard goes beyond energy savings

Levels the Wall for
Improved Appearance

Adding ProBoard siding insulation helps level the wall behind new siding, reducing the visibility of imperfections in the wall that otherwise might create a less-than-perfect appearance.

Protect Against Damage From Pests

ProBoard siding insulation is treated with PREVENTOLTM EPS, a safe insecticide which protects the foam from termite damage. This provides an extra layer of defense between your home and mother nature.
