We would like to get some feedback from contractors who have experience with the Rastra style of ICF (Rastra, Eterna, Cempo, PerformWall, Apex, Amazon Gridwall, etc.). Which aspects made construction easier/faster/better? Which aspects made construction more difficult? What were your key learnings? Let me know if your experience was residential or commercial. Thank you in advance for the input.

I have not used composite ICFs, but I would like to. If I was to build an above grade, stucco structure, I would want to use composite ICFs. I plan on doing just that in Argentina, within a year.
