About Us

Steve Rennekamp has over 40 years of experience in the window industry, but the foundation of his company can be traced back to his childhood. As a kid Steve loved to tinker and experiment, building contraptions and developing his passion for engineering. And because of his height (he’s 6′ 8”!), Steve also played basketball, where he learned about the value of teamwork and working hard. Steve received a degree in Engineering from NYU and went on to work for Alcoa, an aluminum window manufacturer, after college. He was on the team that designed and tested the first thermally improved window.  Steve’s experience helped spark an idea for a new window; now known as the Energy Swing Window, this product revolutionized the window industry because of its easy to use, easy to clean, and energy efficient nature. This window was patented in 1995 and went into full scale production in 1999, and Energy Swing Windows has been a major competitor ever since! The lessons Steve learned throughout his life have helped contribute to the success not only of his product, but also of his company as a whole – the entire team at Energy Swing Windows works hard every day to communicate and deliver quality products to our customers, all under Steve’s leadership.
