Of the more than 126 million housing units and commercial buildings in the U.S. (U.S. Census Bureau report), almost all are at some point likely to experience some form of excessive indoor dampness such as a water leak or flood. And when there is excessive moisture as well as a sufficient food source, mold can grow and lead to poor indoor air quality and resultant serious respiratory ailments.
Todays steel framing construction technology can help mitigate the growth of mold in building homes and non-residential buildings. Cold-formed steel-framed structures are stronger, more resilient and offer a tighter building envelope since members are dimensionally straight and connected mechanically (screwed vs. nailed). This means no nail pops or drywall cracks (e.g. where the roof meets the walls).
Ventilation is efficiently built into the design, and energy efficiency is maintained or increased due to steels inorganic properties. Moisture does not get into steel studs, substantially eliminating the expansion and contraction of construction materials around windows and doors, where leaks can occur. And steel does not provide a food source for mold to grow.
Furthermore, with steel framing technology, building components are often built off-site in a controlled environment, and then installed on the job-site. Processes of building with steel have become so efficient and economically feasible that builders are increasingly choosing to use steel alone or with other building components.
