"The other benefit of the fiber composite rods is they allow the individual wythes to act independently of each other," he explains. "For example, if you have a 90 degree day on the outside and you want to keep the inside at 60 degrees, the concrete on the outside is going to expand from the heat. This system allows that to expand on the exterior and have independent movement from the interior wythe."

Insulated tilt-up wall panels have opened up new markets for C.E. Doyle, having success on several types of buildings including commercial, industrial, warehousing and manufacturing spaces, even a dog kennel. Doyle says his company constructs a lot of freezer and cooler space because of the energy efficiency performance of the insulated tilt-up panels.

"Initially we had to market the insulated tilt-up heavily because there wasn't any tilt-up being done in this state," he explains. "Since tilt-up has become accepted in the state of Wisconsin, now we have a customer base that looks for it. We have builders, architects and designers calling us every month to find out if it's a viable option for their project."

Doyle says business has been solid this year for the company's insulated tilt-up market. They've completed four projects so far this year, have four more to finish by the end of the year, and have leads into next year.
