Extreme Structures LLC provides Insulspan Structural Insulated Panel Systems, (SIPs) for use in both residential and commercial building projects since 1995. These Panels provide builders and homeowners with energy efficiency, superior structural integrity, and an easy to install building system. Replacing traditional stick built construction, SIPs are easy to work with and versatile for exterior walls, roofs, floors and additions.

Extreme Structures LLC also specializes in foundations using ICFs (Insulated Concrete Forms.) ICFs create a warm, dry, solid foundation on which to build. Attainable r-values from R-30 up to R-50 will help keep your house warm in the winter, cool in the summer. ICFs also have shown to be extremely resistant to destructive forces such as, tornados, earthquakes, fire, and hurricanes. Since you will have a strong super insulated, airtight house, why not put it on a strong, super insulated foundation?

Whether you build or we build, you can choose from our stock plans, your own plans, or we can help you design the home of your dreams. We are licensed and fully insured.

Why Go Green?

The simple answer is money. Building with green methods means you will keep more money in your pocket in the long run. Along with money, sustainability is a huge advantage of Green building. Imagine having a home that that takes little or no money to operate-having smaller heating and cooling bills.

Other benefits include:

With SIPs and other products that we provide, the possibilities for energy efficiency are virtually unlimited.

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.
