Abstract: A wall system comprises a plurality of supporting frames and a plurality of wall panels associated in pairs with each respective frame. The two panels of each pair are interconnected in the regions of their upright marginal portions so as to extend in mutual parallelism and to define a space in which the upright supports of the associated frame are accommodated with clearance from each of the panels. An insulating member is accommodated between one upright support and one of the panels, and another insulating member is accommodated between the other upright support and the other panel.
