Metal can be formed into several shapes, sizes, colors, and textures to meet almost any aesthetic. If specified correctly, the assembly will last for the life of the building with very few issues. Three broad categories—composites, insulated metal panels (IMPs), and single-skin—of metal rainscreens are widely used.
The term rainscreen refers to a building system fulfilling one of the main functions of an exterior wall—to screen out rain and keep a wall dry. While at one time that system would have encompassed moisture control alone, the complexity of exterior wall assemblies now requires a more integrated approach. Multicladding aesthetics with the benefit of continuous control layers are achievable with new rainscreen system designs.
Fiber cement can increase the resilience of homes and other structures in the face of environmental threats posed by the sun, precipitation, wind, and fire. In order to maximize the performance of fiber cement against the elements and to successfully install them, owners and builders must be aware of clearances, flashing, placement of joints, proper installation tools, and other requirements provided by manufacturers.
During the last decade, the construction industry has seen an evolution of finishes and applications. This has changed the way metal panels are being designed—they are no longer viewed just as a durable means to enclose a building. This change in perception can be seen in the adoption of a complex metal rainscreen system comprising interlacing patterns to form beautiful, complex façades.
