We’ve chosen to use ecoStyrofoam insulation blocks for a number of reasons. One of those reasons is that it gives very good resistance to heat conducting out through the material and is extremely air tight.
I have a complicated basement. The foundation wall is 22 feet high because I’m on a steep bank of a hill. Most foundations are maybe four feet or eight feet high, so there’s some significant geo-technical challenges there. To do the forming out of regular insulation material would require quite a bit of stripping, building and tearing down which would be very time consuming.
