Extreme Structures LLC provides Insulspan Strucural 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.

Why Go Green?

The simple answer is money. Building with green methods means you will keep more money in their 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

We are proud to say that we are the only green built home in our town. Our new house was completed in March of 2008 by Jon Morehouse and Darren Harrington of Extreme Structures LLC of Denmark, WI. Our family was seeking to build a new home with many sustainable features, which is what drew us to the energy efficient qualities of Insulated Concrete Forms (ICFs) and Structural Insulated Panels (SIPs) during the summer of 2007. After completing the custom design and discussing our options with Extreme Structures, we decided that ICFs and SIPs technology was a great option for this project. The inherent energy efficient qualities of the construction and design has proven successful through our first winter in the new house as our monthly energy costs are approximately 2/3 of what they use to be, in a house that is almost twice as large and on two levels. In addition, our summer cooling bills have reduced significantly as well. Our experience in working with Extreme Structures and their partners was productive throughout, the project schedule and execution of design ran smoothly and was completed within budget requirements.
