I sent out the rough design to five SIPS manufacturers on the East Coast and requested a quote for the product in their core expertise. For some manufacturers this was simply an EPS panel and for others this was a top-of-the-line Polyurethane panel.
The table below shows the rough quotes provided for the house; a 1500 square foot structure with a 12:12 roof pitch:
