What Our Customers Have To Say
Our Insulspan SIP home was delivered mid June of 2006. Within 2 days our 1560 sq ft home was set up on our concrete pad and was covered in house and roof wrap. I cannot say enough about the excellent workmanship provided by Jon Morehouse and his crew. The cost of heating our SIP home located in West-central Illinois near Moline, IL was $150 for the entire winter of 2006-2007, $180 for the winter of 2007-2008 and from 10-10-08 to 2-1-09, the cost was $112 with the average temperature during November, December and January averaging 8-10 degrees below normal. We are very happy with our Insulspan SIP home and would make very few, if any change if we were to build again.
