We have grown substantially since our beginning in 1967. In addition to our main location in Northglenn, Colorado we added a manufacturing site in Pana, Illinois. Why is that important? Because we are strategically located to better serve our customers.

Our headquarters in Northglenn is home to engineering, customer service, sales and operations (all with market specific responsibilities) as well as manufacturing.

The Pana, Illinois location is the home of National Greenhouse Company, a division of Nexus Corporation which has been the leader in the design and manufacturing of conservatories, research and educational facilities since 1919. In 2012 the Pana plant was doubled in size for additional capacity and automated fabrication lines.

Our manufacturing locations are state-of-the-art facilities incorporating robotic and high-tech equipment to ensure the production of quality products for our customers.
