Extreme Panel Technologies
Manufacturing
Extreme Panel Technologies began manufacturing structural insulated panels in a 500 square foot shop in 1992. Because of a growing demand for SIPs, a 10,000 sq/ft manufacturing plant and office was built in 1994. Then Extreme Panel added another 51,000 sq. ft. facility to incorporate a fully automated laminating press to accommodate manufacturing 8' x 24' jumbo panels.
To obtain the highest quality of finished products, a computer-operated CNC machine was installed in 2008. Co-owner and CEO Terry Dieken, focuses his efforts on research to develop new products, increase awareness of SIPs and continue to automate the plant as the market dictates. Dedicated to advancing SIP technology, Terry is also an active member and a past Board President of the Structural Insulated Panel Association (SIPA). Terry's son, Jeremy, runs the day to day operations and currently sits on the SIPA Board of Directors and also serves as the Chair of the Manufacturer's Committee.
