Abstract: A construction wall system comprising, an inner rigid panel and an outer rigid panel of rectangular shape and defining length and breadth dimensions and defining side edges on either side and end edges on ends. The panels being spaced apart from one another with plurality of intermediate junction strips secured between the inner and outer panels, in parallel spaced apart relation, at spaced intervals. A plurality of end junction strips are secured between said inner and outer panels adjacent opposite side edges thereof, and spaced inwardly from the side edges to define junction channels along the side edges between the inner and outer panels. A plurality of spacer strips are secured between the inner and outer panels the spacer strips being spaced inwardly relative to the end edges of the panels to define end junction channels between the inner and outer panels.
