Why not? There are actually several good reasons. Corten is a non-reflective material meaning pretty much the opposite of a sustainable sound “cool roof.” Plus, it’s important to keep this material well drained (and out of contact with standing snow, standing water or even a pile of wet leaves). And the very rusting weathering process that protects Corten steel can then drip rust-colored water onto adjacent surfaces like sidewalk or siding and stain them permanently.”
At moss, we like to use Corten as a rain screen material. That means it is used as an exterior wall panelling but set off from the structure with an air gap, allowing air to circulate completely around it. The outer material protects the (hidden) weatherproof layer of the building from rain and impact damage, but remains separate from the building structure. We’ve done that effectively at both Crew Bar + Grill (above) and at Jordano Photography Studio.
