What it does
CU 21 42 excludes injury or damage arising out of the design, manufacture, construction, installation, repair or inspection of an exterior insulation and finish system. ISO revised it to a 06 26 edition and added CU 34 60, a version with an exception for drainable EIFS not installed over wood.
Who needs it
Building contractors, stucco and siding trades, and developers of buildings clad with EIFS.
How it fits the umbrella
The umbrella has its own exclusions that apply whether or not the underlying policies cover the claim, and many ISO umbrella exclusion endorsements mirror a CGL or auto exclusion so that the umbrella does not drop down where the underlying is excluded. When an underlying policy carries an exclusion, check that the umbrella carries the matching CU endorsement, or explain the gap if it does not.
Quoting and selling notes
- Ask whether the insured installs or repairs EIFS and whether drainage-type systems are used; CU 34 60 may be available.
