For both modular and traditional site-built construction, the final building enclosure is generally the true exterior of the building. However, a unique consideration of modular construction is that each module often needs its own protective layer during storage, transportation, and installation. Modules may also include other factory-installed components, like insulation and cladding systems. This article describes how traditional building enclosure design considerations translate to modular projects. The topics in this article represent some of the greatest challenges and benefits of modular construction, including how the protective layer functions during pre-site construction phases and how this layer, and other prefabricated enclosure layers/systems, may become part of the final building enclosure.
