I'm sure that careful work could yield a two-sided part, but, yes, it would likely be a two-part mould. However, in the article which I cited, the author used Tichy multi-pane windows as part of his "masters" for the wall castings, and they reproduced very well with a cross-section of only .015" or .020". You could make the two sides as separate castings .040" or .050" thick, then cement them together back-to-back.
