Abstract
An improved concrete wall structure is provided with an insulation layer sandwiched between concrete layers. The insulation layer includes a vapor film on at least one side. An extruded channel member is fit onto the edge of a sheet of insulation and has a vapor film fit into a longitudinal groove extending along the channel member. The vapor films on the channel members of adjacent wall panels cooperate to bridge the gap between adjacent panels and thereby provide a vapor seal in the space between the adjacent panels.
