WebFor insulating materials (or materials that have unknown band gaps), I recommend using Gaussian smearing (ISMEAR=0) since it is appropriate for both conductors and insulators, although there are better choices for conducting materials. For insulating materials, I recommend settings SIGMAto 0.01 eV as a reasonable initial test.
