Challenge: A miscalculation in the amount of space required behind the spandrel panels for suitable insulation to be installed occurred. There was not enough room to install thick enough insulation to bring the overall building U value down to specified levels.

Solution: CUIN Ultra was used in place of a standard insulated spandrel panel and insulation. With a U value of just 0.2W/mK, no insulation was required to be installed behind the panel. Subsequently, the building passed its U value requirement.
