Insulated metal panels (IMP) are becoming the preferred material for ductwork within food plants for their efficient, hygienic and durable qualities. IMPs consist of two steel skins injected with urethane foam insulation, providing a better-insulated solution than traditional ductwork. The steel skins can be constructed of standard pre-finished metal or stainless steel to meet the required sanitary specifications. Panels are cut and fabricated to meet the specific size and space requirements of a facility, and joints are installed together with caulks, urethane spray foam, sealants, vapor barriers and fasteners for an air/vapor-tight construction.
