A heat shield for use with freestanding fuel-burning stoves, furnaces, fireplaces and the like, in the form of a modular panel assembly for securance over a wall in spaced relation to said freestanding unit; parallel-spaced, large area, anti-buckling specially-contoured partitions behind the front face of the panel assembly define plural vertical passages layered over the wall for air entering at an intake at the bottom and exiting at an exhaust at the top; louvers at the intake and exhaust align with the respective plural air passages and co-act with the interior partition structure of the invention to produce a sharp thermal gradiant between the front face and any wall protected from a source of heat by the invention, the front face of the panel assembly being hottest, and successive interior partitions and the wall protected being successively cooler as result of convective cooling combined with radiative shielding; special slot and attachment structure further prevents buckling from thermal expansion.
