Abstract
A modular wall liner panel for use in a duct system for containing a flow of gases comprises a central wall segment having a polygonal shape forming an inside wall surface of the, duct and having angularly intersecting pairs of parallel edges. Integral mounting edge flanges are provided adjacent the respective edge of the central wall segment adapted to be detachably securable in place on a supporting grid structure of the duct system wall structure. The grid structure has a plurality of elongated first and second parallel support elements extending transversely to one another and fasteners are provided for detachably securing at least one pair of mounting edge flanges of each duct liner panel to a pair of adjacent parallel support elements of the grid structure.
