A façade suite that incorporates a rainscreen cassette system has many advantages over a proprietary panel on rail system because the cassette is generally designed to be installed over a unitised system that integrates the air seal (and insulation). This is the key flexible advantage that allows the designer to freely design flat or 3-dimensional panels over the façade, which under normal circumstances may become complex or even impossible junctions to manage with regard to weathering. A cassette system may incorporate folded ACM, zinc, stainless steel, surface finished aluminium or terracotta. Thermosash have engineered a unique method of fitting of brackets that eliminate potential wind uplift and, because of the unitised panel supporting the cassettes, also absorb seismic or differential structural movements without compromising any of the junction or critical weathering detailing.
