EIFS foam board is installed down to finished soil at a landscaped wall base. The detail requires clearance above grade. What is the proper field response?
Correct Answer
C) Trim and terminate EIFS at the required clearance with proper base detail
EIFS should be terminated at the required clearance above grade with the proper base detail to limit moisture, insects, and impact damage. Other choices bury or conceal a moisture-sensitive base condition.
Why This Is the Correct Answer
EIFS should be terminated at the required clearance above grade with the proper base detail to limit moisture, insects, and impact damage. Other choices bury or conceal a moisture-sensitive base condition.
Why the Other Options Are Wrong
Option A: Accept it because soil protects the base
In thermal and moisture protection, Accept it because soil protects the base is the wrong selection for EIFS base termination: it points to Accept it because soil protects the base, but.
Option B: Bury the mesh coat for impact resistance, leaving eIFS base termination unverified
The trap in B is Bury the mesh coat for impact resistance. That selection is wrong because it answers the EIFS base termination prompt with the wrong practical move.
Option D: The roofing crew should paint the below-grade foam black
Choice D (Paint the below-grade foam black) is rejected because the option shifts to a different trade task; the tested EIFS base termination function or field correction is Trim and terminate EIFS at the required clearance with proper base detail.
Memory Technique
Use the phrase "problem, control, result" for EIFS base termination; the result side is Trim and terminate EIFS at the required clearance with proper base detail.
Reference Hint
Open ANSI/EIMA 99-A-2017, Exterior Insulation and Finish Systems; use the index entry or section for "ANSI/EIMA 99-A-2017 EIFS base termination and clearance" to confirm that EIFS should be terminated at the required clearance above grade with the proper base detail to limit moisture, insects, and impact damage.
