One could boil down our job as enclosure consultants to this: help people to keep water from accumulating where it shouldn’t.
Water causes all kinds of trouble with many building materials. Wood rots, steel corrodes, masonry spalls and cracks, microbes and fungi grow. Gypsum that once formed solid panels turns to mud.
We call these parts of the building—the ones damaged by water—the “moisture-sensitive” components. The main goal of the building envelope is to protect these moisture-sensitive components from exposure to water. Sounds simple, right?
Unfortunately nature conspires to foil our water control efforts in a variety of ways. In this post we’ll explore some less-than-obvious ways that water ends up where it can cause problems.
