Frequently Asked Questions: Commercial ACM Rainscreen & Insulated Metal Wall Panels (IMP) in St. Paul, MN
What is the difference between ACM panels and Insulated Metal Panels (IMPs) for our St. Paul building?
ACM (Aluminum Composite Material) consists of two coil-coated aluminum skins bonded to a fire-retardant core and installed as an open-joint or wet-sealed rainscreen over exterior mineral wool insulation—ideal for Class A office and medical facades in St. Paul. IMPs have a thick rigid foam core sandwiched between steel skins, providing structural wall enclosure and R-20 to R-45 insulation in a single pass for warehouses and plants in Midway Industrial District, Energy Park, Westgate Business Park, Riverview Industrial Park (West Side Flats), Downtown Lowertown & Skyway Core, Red Rock Industrial District, Empire Builder Industrial Park.
When does St. Paul Department of Safety and Inspections (DSI, 375 Jackson St) require NFPA 285 fire testing on exterior wall assemblies in St. Paul?
Under Chapter 14 and Chapter 26 of the Minnesota State Building Code, multi-story Type I, II, III, and IV commercial buildings in St. Paul using foam plastic continuous insulation or MCM/ACM panels above 40 feet must use tested NFPA 285 wall assemblies with perimeter fire containment.
Can Insulated Metal Wall Panels be installed during sub-freezing winter weather in St. Paul?
Yes! Because IMPs fasten mechanically to structural steel girts with factory-installed non-skinning butyl joint sealants rather than temperature-sensitive wet stucco, our crews install IMPs across Ramsey County 12 months a year.
Why do older metal-clad buildings in St. Paul have dark vertical ghosting lines and high heating bills?
Older buildings used continuous galvanized steel Z-girts bolted directly through the exterior insulation, creating a massive thermal bridge that cuts real-world R-value by 50%. We upgrade to thermally broken fiberglass clip systems.
