We provide and install Structural Insulated Panels (SIPs). Whether you are looking into construction of a new home, a commercial building or a vacation home, or simply looking to add on, our Insulspan Structural Insulated Panels (SIPs) is the ultimate in construction methods. Replacing traditional stick built construction, SIPs are easy to work with and versatile for exterior walls, roofs, floors and additions. The SIP’s are composed of a continuous core of rigid foam insulation, which is laminated between two layers of structural board bonded together to form a single solid panel. They are then prefabricated inside a controlled environment following specific blueprints and architectural plans. The advantages of such a system are extensive:

Extreme Structures LLC also specializes in foundations using Insulated Concrete Forms (ICFs). Using ICF’s create a warm, dry and solid foundation to build on. They offer several of the benefits listed above for the SIPs. In addition, ICF’s have been shown to be effective in resisting natural disasters, such as tornadoes, fire, hurricanes and earthquakes.

Together, Structural Insulated Panels and Insulated Concrete Forms provide an unbeatable combination in construction methods. Whatever your needs might be, let Extreme Structures LLC help provide you with a safe, energy efficient and value-driven building. At home, at work, at play, since 1995 Extreme Structures LLC has been there to lead the way.

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.
