Insulated Metal Wall Panel Systems

Every building project follows a different set of parameters and, as such, may require a different set of wall panels. With NBS you have a selection of insulated metal panels to accommodate the needs of any project. Our IMP profiles are 40" wide, install quickly, and are ideally suited for commercial and industrial applications. Fasteners are concealed within the panel side joint, and the attractive profiles break up the flat expanse of metal on large projects such as manufacturing plants or warehouses. Trim is smooth for all wall panel types, excluding AdobeTexture.

Features and Benefits

  • The double tongue & groove is self-aligning and weathertight. 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 and 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, with 24ga and 22ga optional for some profiles.
  • Panels are available in 2", 2.5", 3", and 4" thickness with lengths that can range from 8'0" to 50'0", depending on solar loading.
  • Fast, single component installation eliminates the inefficiencies of multi-piece, field assembled wall systems, saving installation time as well as labor costs.
  • AdobeTexture™ offers a factory-rolled texture with a matte stucco appearance and eliminates the need for additional coatings.

Notes: Spans shown are based on a transverse load testing of panels per ASTM E-72. Thermal effect due to temperature differentials have not been considered. Loads shown do not include a check of the attachment to the supports. Attachment requirements will vary based on the project wind load requirements. Loads shown are based on panels with 26 gauge interior and exterior facings.
