As an alternative to removing and replacing the original masonry—an approach that can negatively impact structural integrity—project teams and architects are encouraged to design an insulated facade layer with vapor barrier, creating a new enclosure that is watertight and energy efficient, and possibly more attractive. This raises a question about how to ensure the ideal placement and attachment of the insulation, air barrier, and cladding.
How can designers, specifiers, and contractors capitalize on the growing trend of multiple aesthetic looks for a building’s exterior while ensuring the structural stability of a building enclosure? The connective tissue to solve this equation lies beneath what the eye can see. It is a singular, cohesive building envelope which relies on exterior continuous insulation (ci). Employing materials to work in concert with each other can deliver key value propositions, such as design freedom, long-term performance, potential cost savings, and peace of mind.
Older masonry structures from many eras, including libraries, town halls, commercial blocks, and school buildings stand at the geographic center of many communities, holding symbolic meaning and serving varied needs and purposes. As they age, many begin to show the effects of neglect, weather and deferred maintenance on their façades, foundations, and roof assemblies.
When prefabrication enters the construction equation, the game changes dramatically. Manufacturers can produce complete exterior wall panels in a climate-controlled facility with no weather limitations. Wall panels can then be transported to a job site where they are hoisted into place and attached to the structure without the need for exterior access.
When it comes to framing, there is no more resilient option than cold-formed steel (CFS). By analyzing resiliency in the context of the built environment, this article will explore the various attributes of a resilient structure, and make the case for why CFS performs best in each scenario.
