A new study has been released by the U.S. Department of Housing and Urban Development that shows builders how to improve the durability and energy efficiency of their homes by combining structural insulated panel roof systems and concrete wall systems. The connection details and engineering provided in the study give builders a reliable and consistent method for connecting the two systems in one- and two-family dwellings.

The Prescriptive Method for Connecting Structural Insulated Panel Roofs to Concrete Wall Systems covers all types of concrete wall systems, including insulating concrete forms, concrete masonry, removable form systems, precast wall panels, and autoclaved aerated concrete products. Homes built in high wind or seismic zones, however, are not covered.

Funding for the study was provided by HUD’s Partnership for Advancing Technology in Housing program that aims to break down the barriers for innovative housing technologies. Support for the development of the study was provided by the Structural Insulated Panel Association and the Portland Cement Association. For more information, visit www.cement.org.
