WallPanel™ System (WPS) are assembled with standard galvanized steel structural framing members. All exterior framing members are press fitted into two pounds density EPS composite insulation, generally 6″ thick in wall panels and roof panels, with our Multiceramics™ coating providing thermal break over all members. All joints and cracks are spray-foam sealed to provide a virtually airtight building envelope. Interior wall panels are typically 4″ and 6″ insulated panels.
