STANDING SEAM INSTALLATION VS TRADITIONAL METHODS
Standing seam cladding systems offer significant advantages over traditional rainscreen solutions like cassette and rivet fix systems, particularly in performance, aesthetics, and durability. A major benefit is their ability to accommodate thermal movement. Using fixed and sliding clips, panels expand and contract naturally, reducing stress and preventing buckling or cracking over time.
By contrast, cassette systems rely on rigid fixings that restrict movement, often causing misalignment and wear. Rivet fix systems, while easy to install, lack flexibility and are prone to loosening or corrosion. Visually, standing seam cladding delivers a sleek, contemporary look with concealed fixings and uninterrupted lines- enhancing architectural appeal and weather resistance. Interlocking seams also prevent water ingress, making them ideal for exposed environments.
Cassette systems, though clean in appearance, have pronounced joints that disrupt visual flow. Rivet fix systems expose fasteners, creating an industrial aesthetic that may not suit modern designs. Fire safety is another area where standing seam systems excel. Their minimal cavity space and concealed fixings reduce airflow behind panels, limiting the chimney effect that accelerates fire spread. Cassette systems, however, can create airflow pathways, as highlighted in the Grenfell Tower fire analysis.
