History

Eastern Architectural Systems (EAS) became part of the Cornerstone Building Brands family in December 2023.

Prior to the acquisition, EAS was a wholly owned subsidiary of Eastern Metal Supply (EMS). EMS purchased
Flesher Windows in 2011 and rebranded the company as Eastern Architectural Systems.

EAS still offers a host of premium aluminum and vinyl impact windows and doors. The Cornerstone Building Brands/EAS leadership team takes pride in its employees and the service they provide to the customers. As always, service and quality remain EAS’ main priorities.
