Metl-Span’s CF Mesa insulated metal panels are the total package when it comes to building envelope solutions. The low-profile corrugated panel of 1/8” rib not only offers thermal, vapor, and moisture barriers in a single component, but delivers high R-values to create an energy-efficient environment as well. The Mesa profile is designed with concealed clips to decrease thermal bridging and is well-equipped for exterior walls, interior walls, and ceiling applications. You can choose from an embossed or un-embossed profile with a face made of galvanized or aluminum-zinc-coated steel.
Similar to our CF Light Mesa panels, our CF Mesa insulated metal panels are used for used for commercial, institutional, and industrial buildings. By incorporating sustainability factors into their design, the Mesa profile adheres to green building standards where energy efficiency is paramount.
Mesa panels are also ideal for cold storage applications, including dry goods warehouses, cooler and freezer buildings, food processing facilities, and all temperature-controlled environments. Contact our representatives today to learn more!

1. Metallic paint finishes will exhibit color shift, shade variances, striations and longitudinal patterning that are inherent characteristics and are not a product defect or cause for rejection.
2. All Metl-Span colors are formulated to provide maximum energy-efficiency and solar reflectivity. All standard available Premium I and Premium II colors have been formulated for maximum solar reflectance.
3. Prices vary by color, gauge and quantity of metal. Please contact your Metl-Span representative for complete information.
4. All colors shown are approximate actual finish colors displayed as accurately as possible.
5. Light Stone – Tuff Cote® does not match the Light Stone – Standard SP color offering.

IMPORTANT NOTES:
Deflection caused by temperature differential induced thermal bow is not addressed in the above table and may result in allowable spans that are less than the spans listed above and may require the use of heavier 24 or 22 gage panel facings at added cost. Except for self-supporting the dead weight of the panel, partition wall panels are non-load bearing. Ceiling panels must be supported from the structure above or by an internal support structure. Panel skins must be captured at both ends of the panel by supporting members designed to support reaction pressures from a 5 psf interior pressure. CF-42 = 42″ wide. CF-45 = 44.5″ wide.

The owners of Electronics for Imaging (EFI) had high expectations moving into a new east coast headquarters in Londonderry, N.H. Versatility, durability, ease and speed of construction as well as aesthetics all played a role in the selection of insulated metal panels from Metl-Span for the 185,200 square foot project – that’s a little more than four acres!

Wurstfest is a popular annual celebration of German culture in New Braunfels, Texas. Just days after the successful November 2019 event wrapped up, a fire damaged the large facility that hosts the 10-day festival. With less than a year to reconstruct the 27,000 square foot facility for the 60th annual event in November 2020, there was no time to waste.
