    Default Eco Block ICF

    I can't find any specs in their instructions that require them to be covered on the exterior of the house. Anyone know of a IRC requirement?

    Cool house today. It was designed by Frank Loyd Wright's company. The addition in 1999 made it even nicer, and it's a stylin' place now.
