CF Light Mesa

CF Light Mesa is an industry-leading, light-profile insulated metal panel designed for use in applications where energy efficiency is paramount. With a slightly shallower profile than the original Mesa profile, the minor corrugated rib of 1/16″ depth provides a flattened appearance and creates an easily washable surface. The Light Mesa is the insulated metal panel of choice for use for exterior and interior walls as well as ceiling applications.

Light Mesa panels are ideal for cold storage applications, including dry goods warehouses, cooler and freezer buildings, food processing facilities, and all temperature-controlled environments. This insulated metal panel are for achieving and maintaining critical temperature controlled and insulation values. Metl-Span also offers USDA-compliant stainless steel for use in daily washdown areas. Contact our representatives today to learn more.

Design Features and Benefits

  • Flat surface, easily washable, shallow profile insulated metal panel
  • Utilizes concealed clips and eliminated thermal short circuits
  • Easy and fast installation, with reduced construction labor costs
  • Interior and exterior applications
  • Vertical or horizontal orientation

Colors

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.
