Rain screen cladding systems aim to protect a building’s wall construction from damages that can occur through moisture penetration. The air cavity design behind a cladding material allows air to flow through the space, which dries the insulation as well as the back of the cladding panel.
The fiber cement product line offered by American Fiber Cement Corporation is installed as a rain screen system. As the system mitigates mold and other moisture related issues in a wall, the fiber cement panels also benefit from the use of a rain screen to keep them dry and thus preserve their look and composition.
The panels are attached to the wall substrate with horizontal and vertical profiles, which hold the panel’s 3.2 lb/ft2 of dead load as well as the wind load forces on the panel. The vertical channels provide a desired chimney effect, which produces air flow along the wall cavity.
