The Foam Sheathing Committee (FSC) of the American Chemistry Council focuses on developing solutions to building code issues and promoting the sound technical use of foam sheathing to the construction industry. FSC facilitates broader acceptance and effective use of foam sheathing products through market education, technical and advocacy support on U.S. building codes and standards and by demonstrating the benefits of foam sheathing products. FSC leverages and works in coordination with ACC’s Plastics Building and Construction Team and ACC’s Center for the Polyurethanes Industry as needed to maximize value and help avoid or resolve conflicting interests.


FSC’s primary membership base is manufacturers of rigid plastic cellular foam insulation products including expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate or polyiso (PIR).

Technical Resources:

With the support of members and aligned industry groups, FSC is pleased to offer a wealth of technical resources on foam sheathing, including properties, applications, installation, and building and energy code considerations.
