Hot-box tests for building envelope condensation assessment

A common architectural feature of curtain wall facades is constituted by a transparent double-glazing unit mounted in front of a recessed interior metal panel. It is typically installed in spandrel areas, where its required to provide to the faade not only surface consistency but also depth.To evaluate condensation risk on this type of envelope element, an experimental program has being carried out on a typical facade panel (Shadow-box) provided by Permasteelisa.
