Windsor Windows and Doors has invested in a new technology that enables it to paint its products in-house with a wider variety of colors. The fully automated state-of-the-art powder coat paint line will increase the West Des Moines-based manufacturer's standard color palette from seven colors to 22 for its Pinnacle and Legend HBR brand windows and patio doors. The company has hired approximately 10 additional workers for the new line. The investment speaks to the company's optimism, Windsor President Mark Rieser said in a release. "We've survived a very difficult recession, and we've come out on the other side even more committed to growth and innovation."
