HPCI Barrier™ Wall Panel
The HPCI Barrier™ insulated barrier wall system provides superior air, water, thermal and vapor protection in a single-panel component. This unique single panel insulated metal wall panel introduces new standards in cost savings, design integrity, and sustainability. Easily and quickly installed in a single step, HPCI Barrier wall panels eliminate the need for multiple work crews and therefore, minimizes construction debris while reducing the likelihood of improper installation.
The values in the table represent PUR values. For PIR, see data sheet.

Load Span Tables
The Load Span Tables below, excluding Partition Wall, are based on Allowable Stress Design (ASD). For loads calculated based on ASCE 7-10 (LRFD), please refer to section 2.4.1 of ASCE 7-10 for the applicable load combinations using Allowable Stress Design.

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.
