A wall panel is single piece of material, usually flat and cut into a rectangular shape, that serves as the visible and exposed covering for a wall. Wall panels are functional as well as decorative, providing insulation and soundproofing, combined with uniformity of appearance, along with some measure of durability or ease of replace ability. While there is no set size limit for a piece of material fulfilling these functions, the maximum practical size for wall panels has been suggested to be 24 inches by 8 feet, to allow for transportation.
Metal panels used as cladding fall into two main categories: sheet metal, flat or corrugated, attached to a back-up system; and “sandwich” panels consisting of two thinner metal sheets over a rigid core.
Insulated Metal Panels are lightweight composite exterior wall and roof panels with metal skins and an insulating foam core. These panels have superior insulating properties, and their outstanding spanning capabilities and one-pass installation makes them quick to install, saving costs compared to other wall assemblies. Insulated Metal Panels are available in a wide variety of colors, widths, profiles and finishes, enabling virtually any aesthetic desired for walls and roofs.
