family. Headquartered in North Carolina, Ply Gem is an

Simonton was founded in Pennsboro, West Virginia in 1946, when Fred and Sybil Simonton recognized the need for high-quality exterior aluminum products and founded Pen Vent Awning. Their son would later help take Simonton to the next level. In 1981, he convinced the rest of the family that in order to differentiate the company from its competitors, they would need to begin producing energy-efficient vinyl windows. As a result, Simonton Windows was born.
