ST40 - Striated Insulated Metal Panels

Where a clean, flat appearance is desired, the ST40 Striated Insulated Metal Panel is a very economical option. Its light embossed exterior is profiled with narrow longitudinal striations that adds rigidity yet helps ensure an acceptable flatness tolerance. Ideal for nearly any application, the ST40 combines the aesthetics of a flat exterior appearance with the high insulation ratings of an insulated wall panel.

Features and Benefits

  • The double tongue & groove is self aligning and weather tight. This allows for sealant application at either the interior or exterior side of the panel joinery depending, on the direction of the vapor drive.
  • Hidden/concealed fasteners give the panel a clean, aesthetically appealing appearance.
  • Removable film prevents damage to the exterior of the panel during shipping and installation.
  • This panel arrives on site in one piece and requires one simple step installation, reducing construction time and costs.
  • Standard exterior and interior steel surface is 26 gauge.
