We discuss Kondo-Heisenberg model in two dimensional nonsymmorphic crystals. On symmetry grounds, we found the symmetry protected metallic phases even at certain integer filling. However in between those metallic phases, both topologically trivial or non-trivial insulating phases are allowed and it turns out that such insulating phase must break lattice symmetries. We also discuss possible experimental applications.
