With energy codes pushing us closer and closer to Net Zero Energy solutions, existing cladding design solutions have had to react by providing higher energy performance characteristics to meet TEDI targets. One such solution has been the application of foamed plastic insulation to the backpans of window wall and curtain wall to improve the overall thermal resistance. However, the use of foamed plastics is regulated in building codes and certain performance requirements must be met.  The intent of this presentation is to discuss the application of spray applied foamed plastic insulation to a window wall system and how this approach was tested to determine if it met the Code requirements.
