Going to add insulation to the facade, starting tomorrow so I need some help

.... I'll cross-batten outside the old panel (removing the rib) and first install vertical 45*45 with 45 insulation at cc60, then outside of that, horizontal 45*45 with 45 insulation and at cc60. Should the wind barrier come next or do you install the battens (22*70) first??....should the barrier be flush against the insulation or outside the battens?...(then the panel goes on top of this...)
Thanks in advance.
