Jerry The product that 3-10 makes is called- Reward - it is an insulating concrete form. There are a number of ICF's on the market. Building with these ICF's give the homeowner many COST saving advantages as compared to conventional stick building. You can build for comparible costs, but, you will have energy savings of up to 75-80%. Which breaks down to money in your pocket. There are energy efficient loans avaible through many national financial institutions which these houses qualify for without any modifications as a stick frame would need. Check out www.Therm-O-Wall.com this is a similar product to the Reward system. There is a slide show on this site that shows you how these buildings go together. There are other good sites to go to also. let me know if you interested. Rob Dykeman
