    SIPs Deliver Winter Surprise for Unsuspecting Owner
    DENVER (ACH Foam Technologies) — When Terry Schroth decided to have his new HVAC, plumbing maintenance and repair building constructed with Structural Insulated Panels (SIPs), he had no idea what would happen on the night of Thursday, January 13th2011. Schroth had been interested in the long-term benefits of SIPs, but as fate would have it, he reaped substantial rewards on a very cold night in January before the building was finished.

    That particular night the temperature dropped to 0° Fahrenheit. The hydronic heating system had not yet been installed. Schroth was understandably worried that his paint and drywall interior finish work would be damaged by the extreme cold. All he could do was plug in two small 1500w space heaters— one in the 50x40 shop with 12 ft ceilings and the other in a smaller office— and hope for the best.

    On Monday morning Schroth visited the structure to assess the damage. To his surprise, the thermometer inside the 2000 sq ft shop area read 60°. No damage had been done to any of the finish work or equipment. “This is amazing—if you can understand the size of this space and these were “milk house” heaters—just little things. Our electrician was blown away that such a small amount of heat was needed to keep this space at 60° through the winter,” said Schroth. “The SIPs walls are phenomenal!”

    According to Gary Sutton of Sutton Construction, the walls are R-Control SIPs, and the only opening in the building was a CHI 3216 10’ x 12’garage door. “This was our first R-Control SIP project yet we were able to erect all of the panels in 36 man-hours. I can’t wait until my next R-Control SIP project so I can apply the time saving methods I learned on this one! My electrician was amazed at how easy it was to snake the flexible conduit through the precut electrical chases in the SIPs,” said Sutton.

    Frank Kiesecker, of ACH Foam Technologies, manufacturer of R-Control SIPs, suggests builders pre-plan for electrical and equipment needs when building with sips.  “During the design phase it’s extremely beneficial to pre-plan for electrical chases,” explains Kiesecker. “Since SIP panels are manufactured to meet the project’s specifications, it’s important to plan for electrical chases in advance to prevent time-consuming and costly changes for modifications during installation. For example, SIP facings should never be cut horizontally for the installation of electrical wiring. Cutting the SIPs will result in compromising the structural performance. Also, during the design phase, it’s important to determine whether there are any equipment needs for the installation of the panels. If the project specifies roof panels or wall and floor panels larger than 8’ x 8’ in size, equipment such as a forklift or crane may be needed to install the SIPs.”

    Schroth added that Gary Sutton did a lot of research on green building materials at the outset. Sutton suggested they use R-Control SIPs because of SIPs’ superior insulative qualities, as well as savings in material waste and labor costs. “I agreed with him. Nothing like a cold night in January to show me I had made a good decision,” remarked Schroth. “When we get the solar installed and hydronic heating system operating, this will be a truly green building. That makes me feel good—and it will cut down my energy costs over the long-run. I can also let people know that TJ’s Maintenance and Repair, Inc. of Morrison, Illinois is a green business.
