What special inspections would one typically require for EIFS? George A. Everding AIA CSI CCS CCCA Cannon Design - St. Louis, MO Ronald L.

For example, Dryvit's report for its Outsulation Plus MD System indicates that the special inspector's duties include "verifying field preparation of materials, expiration dates, installation of components, curing of components, installation of joints and sealant, applied dry-film thickness and interface of coating material with flashing."

After I asked the question, I remembered we had a copy of CASE form 100, which suggests: 1. Material Submittals 2. Condition of Substrate 3. Application of Foam Plastic Board 4. Application of Coatings 5. Application of Mesh 6. Ambient Condition and Curing 7. Flashing and Joint Details 8. Sealants/Caulks 9. Other: I noted too that the 2009 code requires installation according to manufacturer's instructions, along with several other additional requirements that were not present in 2006. These were in the Exterior Walls chapter of the code (14?). So I would infer that these new requirements might provide clues to what the code is looking for in the inspections. George A.

However, they do provide some guidance. Therefore, it is up to the jurisdiction to determine what is required for an EIFS special inspection, and contact should be made with the building department to determine those requirements.

No firm I've worked for, for the past twenty years will allow installation of the material on their jobs. George A.

Although my firm doesn't deal with it extensively I do know that manufacturers have created a "drainage layer" between the substrate and the insulation layer...in effect turning EIFS into a rainscreen principal wall...either by grooved slots or "pucks" on the backside of the insulation as well as a moisture barrier on the substrate. The one job that we have done recently that I spec'd, the acceptable systems were Dryvit Outsulation Plus, Durex Qauntum Select and Durock PUCCS. All 3 met the current requirements for EIFS in ON. Not sure if any of these systems are available or acceptable south of the 49th parallel. Ride it like you stole it!!!
