The Oak Ridge National Laboratory (ORNL) recently undertook a series of trials comparing the moisture and temperature management properties of several different exterior insulation and finishing system (EIFS) configurations with those of other claddings. This article looks at how the research was conducted (along with related modeling software), and focuses on the findings for different types of climate locations, and other data.
“A building is only as strong as its foundation,” is a common idiom uttered across the construction industry. Time can be spent applying this to anything, in the metaphorical sense, but in the construction business it can be taken literally. The foundation is literally the building block on which the rest of a building will rely for long-term function and performance.
The April 2013 issue of The Construction Specifier included a technical feature by J.W. Mollohan, CSI, CCPR, CEP, LEED GA, entitled, “Exterior Wall Assemblies: Are You Getting What You Specified?” We received the following letter from Cliff Black, a CSI member and a building envelope product manager for Firestone Building Products.
Exterior wall systems have received a lot of well-deserved attention as no amount of ink has been spared over the last decade writing about the critical importance of a tight, fire safe, and tested building enclosure. However, the traditional project delivery process seems designed to undermine the intent of achieving a building enclosure that meets all of these criteria even when it has been properly specified.
