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.

Exterior insulation and finish systems provide a number of features and benefits when compared to other claddings. Offering an air barrier, continuous insulation, and a decorative finish in one seamless assembly, EIFS is both versatile and lightweight. This article takes a look at the assemblies in terms of not only air barrier applications, but also panelization, specialty finishes, and testing.

In early iterations of exterior insulation and finish systems (EIFS), issues occurred when board stock rigid insulation was layered against other rigid insulation or exterior sheathing, or when decking traps moisture between the layers of material. That industry has taken steps to eliminate such problems, but what broader lessons can be learned of the importance of preventing your insulation from getting wet?
