Continuous exterior insulation, when used correctly, can resolve multiple building performance challenges. In this presentation, we will look at two topics: condensation and effective R-values. Condensation can lead to mold or rot on building enclosure surfaces, as well as within the enclosure’s inner layers.
Jonathan Smegal’s work for RDH includes laboratory research, hygrothermal modeling, field monitoring of wall performance, and forensic analysis of building failures. Jonathan has managed more than a dozen full scale field tests of wall and roof performance including test huts, test trailers, test houses, and production homes in various locations throughout North America.
In a world where energy-efficiency and sustainable solutions are increasingly prioritized in building projects, it is important for architects, contractors and all building professionals to make informed decisions when selecting components of the building envelope.
Grant Park High School in Portland, Oregon is a multi building campus featuring buildings and additions built over a period of time from 1923-1966. Composed largely of concrete frame structure with brick infill, the cladding has exhibited an accelerated degree of masonry spalling at a number of the buildings on various different elevations.
