CF Mesa

CF Mesa is a corrugated insulated metal panel from Metl-Span with a PUR foam core. Longitudinal planks run along the face, giving a flat, textured look. It is used for exterior and interior walls and for insulated ceiling panels in commercial, institutional and industrial buildings in the United States. The profile is a low-profile corrugated panel with a 1/8 in. rib. The same panel is used in cold storage buildings such as dry goods warehouses, cooler and freezer buildings and food processing facilities.

Mesa is the deeper of two related profiles; CF Light Mesa is the shallower. It belongs with the insulated metal wall panels in the CF wall range.

• Coverage widths: 30 in., 36 in., 42 in. and 44 in.
• Thicknesses: 2, 2-1/2, 3, 4, 5, 6 and 8 in.
• Embossed lengths: 8'-0" to 32'-0" horizontal; 8'-0" to 52'-0" vertical
• Unembossed lengths: 8'-0" to 16'-0" horizontal; 8'-0" to 40'-0" vertical
• CF-42 designates a 42 in. wide panel and CF-45 a 44.5 in. wide panel

The exterior has longitudinal planks at a nominal 4 in. on center, nominally 1/8 in. deep, embossed or unembossed. The interior is Mesa at 1/8 in. or Light Mesa at 1/16 in.

The exterior is G-90 galvanized or AZ-50 aluminum-zinc coated steel in 26, 24 or 22 gauge. The interior adds 304 and 316 stainless, and 22 gauge is not offered in stainless.

The core is foamed-in-place zero ozone depletion potential Class 1 PUR, and a PIR core version is also listed with its own data sheet. The thermal table below gives the PUR values. Mesa panels join through an offset double tongue-and-groove that carries an extended metal shelf for positive face fastening. Concealed clips eliminate thermal short circuits.

The V6 X-Span Clip is the concealed clip listed with the panel, with a matching V6 X-Span Edge Trim. The trims and extrusions drawn in the horizontal details include extended trim legs, drip edge, extruded base, extruded sill, extruded jamb and header, gasket and wet seal.

• Finish systems: Fluropon, Fluropon Premier, Fluropon Classic, Flurothane, Flurothane Coastal, WeatherXL and Igloo White Polyester
• Metallic finishes can show color shift, shade variance, striations and longitudinal patterning
• Light Stone in the Tuff Cote system does not match Light Stone in the Standard SP offering
• Pricing varies by color, gauge and quantity

The k-factor is 0.114 at 35°F mean core. Values below are for a 42 in. width at 35°F.
