Open EIFS: A Resilient 100 Year Wall

Open EIFS is an Exterior Insulation and Finish System that achieves high moisture resilience through increased drying capacity and redundant, yet practical, safeguards.  When implemented holistically, this assembly is both durable and high-performing. The concept builds upon research originally conducted by DOE’s Oak Ridge National Laboratory, which demonstrated high moisture performance in EIFS configured with…

Frankensteinian Design: Energy Efficiency At The Expense Of Durability

Energy efficient initiatives, coupled with the IECC’s requirements for continuous insulation over exterior surfaces, have prompted a vast array of ‘Frankensteinian’ energy assemblies.  From three-coat stucco over outbound EPS to EIFS on structural insulated panels (SIPs), the combinations of such hybrid approaches appear endless.  While the professed energy efficiencies can be impressive, moisture management may…

Reach A Higher State Of EIFS Consciousness

Moisture performance of EIFS is misunderstood and it continues to be a subject of consternation.  Much of the confusion stems from the fact that design criteria for EIFS assemblies incorporating cavity insulation plus outbound insulation panels have not been adequately addressed by the EIFS industry.  Manufacturers place the responsibility of assembly design squarely on the…
