Abstract
A method for producing clad duct from a laminate is disclosed. The laminate is a sheet of thermoplastic material bonded to an insulative foam board. V-shaped grooves are formed in the foam board, opposite the sheet. The sheet is heated in the vicinity of one of the grooves, until pliable. The sheet is then bent, where it has become pliable, to close the groove. The heated and bent sheet is then cooled until it is no longer pliable and retains its bent shape. The heating, bending, and cooling steps are repeated for the other grooves until edges of the laminate are brought together. The edges are then sealed.
