The outer edges of the outermost vertical channels adjacent the vertical window wall opening edges are formed from a resilient material and include an integral, outwardly extending sealing strip which is in sealing engagement with the adjacent window opening edge. The interior vertical channels interfit for ease of installation and removal of the insulating panels and include one channel member which has its outer leg extended to be in overlying relation…
