Infrared maps and fluxes of the supernova remnant RCW 86 (MSH 14-63) were obtained from the IRAS data base, using a destripping and a spectral decomposition technique to isolate the weak IR emission of RCW 86 from all other contributions in the IRAS maps. It is shown that the IR brightness maps correlate very well with the X-ray-brightness, the optical, and the radio images. A comparison with the three other young shell-type SNRs Tycho, Kepler, and Cas A showed that the IR temperatures and luminosities of these objects decrease with age. For all objects, however, the IR- and X-ray-based densities are similar, while the X-ray-derived masses are an order of magnitude above the IR masses.
