    ProBoard® Insulating Sheathing

    ProBoard Original Insulating Sheathing is a closed cell, rigid foam insulation made from expanded polystyrene (EPS). ProBoard is designed for residential and commercial exterior wall applications, to be installed under new siding products. 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 under new siding can help your home meet DOE recommendations.
