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

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.
