Dupont Rigid Foam Insulation replaces non-insulating above-grade sheathing products like plywood, fiberboard and OSB, and eliminates the need for additional air barriers such as housewrap.

Dupont FROTH-PAK Foam Insulation is a two-component professional insulation kit. FROTH-PAK comes as a professional sealant for air sealing gaps and penetrations up to 4 inches wide or as a spray foam insulation to fill larger cavities providing both insulation and air sealing properties.

Dupont insulation products are installed against the exterior side of the foundation wall.
