While
it’s true that water, wind and ice pose significant challenges to any
structural design, building science has come a long way in the defense
against these elements and their potential to cause mold, rot and decay.
When it comes to constructing high-performance building envelopes,
there are a growing number of products architects and specifiers can
choose from to create rainscreens and protect their building’s aesthetic
and structural integrity. That’s why it's so important to understand
thoroughly how these various materials can stand up to Mother Nature’s
worst and protect the health and energy efficiency of the interior
environment for occupants.
The
American Society for Testing Materials reports that “about 90 percent
of all building problems are associated with water in some way.” This
statistic highlights the need for deliberate and comprehensive moisture
management strategies for exterior wall assemblies and products that can
stand up to the elements.
