What’s the difference between sandwich panels and insulated metal panels (IMP)?

The names often get swapped out for each other. Insulated metal panels, or IMPs, are frequently referred to as sandwich panels due to their structure: a layer of foam insulation nestled between two metal sheets. These panels serve as the outer walls and roofs of buildings and consist of a solid layer of insulation sandwiched between two sheets of metal, typically aluminum or steel. The insulating material is injected between these metal sheets and then cut to the required lengths.
