Rob discusses some methods for lessening the likelihood of water intrusion.
In my consulting work I often review the construction details for EIFS projects, both for new buildings and old ones. The former is intended to get it right the first time, while the latter is often an effort to find out what went wrong. This month's column contains a sampling of some not-so-obvious details I've seen while doing these reviews.
The foam is installed and a router is used to make a groove in the foam from the bottom to the top of the wall. The EIFS lamina is then installed, as is a parapet cap flashing at the top. The flashing overhangs the EIFS enough to keep water from getting blown up and under the flashing ... or does it? What about at the aesthetic groove?
