HOW DOES A SIP HOUSE COMPARE IN COST TO A CONVENTIONALLY BUILT HOUSE?
If you compare the cost of building two equal structures one using conventional methods and one using SIPs the difference in the price will be a negligible amount. However, the structure built with SIPs will provide a higher quality structure and the cost of maintaining a comfortable interior temperature (utility cost) will provide very significant savings for years to come. Remember that the panel accounts for only a fraction of the cost of construction, and that the degree and quality of finish materials determine the majority of the cost. With all these things in mind, it is safe to say that if conventional methods are used to build a home that is insulated to the same degree as a SIP home there will be little cost difference. We would add that while there is a little cost difference, there is a significant difference in value.
