A system for insulating a building comprising a first layer of rolled insulation disposed atop a longitudinally extending upper chord of a roof truss, a purlin or a girt of a wall. Discrete insulating spacer members are intermittently disposed atop the first insulation layer and along the longitudinally extending chord, purlin or girt. A three sided bridge with a plurality of tab elements overlaying and contiguous with the insulating spacer members. A second layer of rolled insulation disposed atop the bridge and panel clips secured with a fastener extending through each of the second layer of insulation, bridge, insulating spacer member, first layer of insulation and upper chord.
