The range of energy gap of insulators ,semiconductors & conductors are following:
●E_g for insulator is greater than 3eV . So there is very large difference between conduction band and valance band.
●E_g for semiconductor is less than 3eV. There is not much large and not much small difference between conduction band and valance band.
●E_g for conductor is zero .so conditions band and valance band overlaps each other.
