Sandwich wall construction and dwelling

Abstract

A construction wall system having, rigid inner an outer rectangular panels on either side and end edges on ends. The panels spaced apart from one another, with parallel junction strips between the inner and outer panels, with end junction strips secured between the panels. End junction strips define junction channels along the side edges between the panels, with inwardly spaced spacer strips secured between the inner and outer panels relative to the end edges of the panels to define end junction channels between the inner and outer panels. Panels and strips all being formed of polymer-modified fibre reinforced concrete material, with synthetic plastic foam material filling the spaces between the inner and outer panels.
