The Metl-Span CF Mesa and Light Mesa insulated metal wall panels are well suited for exterior and interior partition wall applications. The lightly corrugated profile on both faces of the panels ensures symmetry from outside of the building to inside, and from room to room in partition installations. The CF Mesa and Light Mesa wall panels may be used for exterior wall applications, but they are not recommended for use on exterior walls of low temperature buildings.

FM Approved Class 1 with no height restrictions.

Metl-Span profiled panels with a urethane foam core have a standard FM Class 1 approval and offer the best insulating values available today.

Panels are lightweight and quick to install, significantly reducing construction time.

A double tongue-and-groove offset side joint permits concealed fastening.

Consistent insulating values are achieved with built-in thermal breaks, saving energy.

The metal and foam composite construction creates a rigid panel far stronger than the individual parts. This increases the span capability of the panels and reduces the need for secondary structural steel components.
