Properties of the $^1S_0$ superfluid phase are studied forsymmetric nuclear matter at finite temperature. It is describedwithin a covariant hadronic field model, of the $sigma -omega$type, with addition of density dependent correlations simulatingeffects due to finite extension of nucleons. The model is solvedin a selfconsistent Hartree-Bogoliubov approach, assuminginstantaneous interactions in the superfluid phase. A comparisonwith the results obtained from several hadronic field models ismade. Main characteristics of our description of the superfluidgap are in qualitative agreement with some studies usingmicroscopic potentials, although further refinements could improveits performance.
