One of the first questions we are ask is, "what is the cost of the system?" This system is more economical than conventional construction because of the fantastic benefits, continued savings in energy cost (this alone could pay for a good portion of college expense), downsizing heating and cooling equipment and associated ducting, rebates from local energy companies, lower insurance cost, lower maintenance cost, quicker sale and higher resale values. The initial investment is a little more than a conventional construction, somewhere in the order of 2 to 3% increase in the overall cost of a new home. The accompanying charts is an attempt to do an apples to apples comparison of our wall system to different modes of construction. However, you must keep in mind that a conventional construction can not compare to the benefits of our wall system. It would be the same as trying to compare a used Ford Escort to a new Lincoln.
