What Our Customers Have To Say

Living in an Insulspan SIP home on Lake Winnebago has exceeded our greatest expectations. Extreme Structures LLC, the Insulspan contractor used Insulspan Structural Insulated Panels (SIPs) to design and create the home of our dreams. Value and quality were obtained with no costly architect required. The precut panels were erected in minimal time to our great satisfaction. Timber frame construction along with the panels allowed for an open floor plan. The vaulted ceilings accommodate a 21 foot stone fireplace to create a dramatic living area. Insulspan offered unique architectural features at reasonable construction costs. The energy efficient SIPs and ICFs along with an effective heating and cooling system maintained even heat and cooling throughout the entire home. This allowed the use of more square footage for living space. The 6,000 square foot home includes a lower level, with another large stone fireplace and the area above the 2,000 square foot heated garage which includes three overized bedrooms and a generous bathroom. The coziness and beauty of our home represents an architecturally unique home. People dream of exotic vacations, we dream of staying home and enjoying our SIP lake home.
