Radiant Engineering offers a unique combination of textbook mechanical engineering and modern design practice with practical real world professional hands-on practice. We build what we design and we service what we build. We offer professional design and engineering in addition to custom equipment fabrication. Established in 1979 as Suncraft Inc., the company initially specialized in solar energy. Within a few years, Suncraft Appropriate Energy Alternatives, Inc. was pioneering radiant floor heating systems across Montana, and this focus for the business was reflected in the name change to Radiant Engineering, Inc. in 1996.
