About Lindsay Windows
Lindsay Windows is a family-owned window and door manufacturer headquartered in North Mankato, Minnesota. Founded in 1947, the company has operated independently for over 75 years - no private equity, no corporate parent. Lindsay manufactures vinyl replacement windows, fiberglass and steel entry doors, sliding patio doors, and French patio doors across multiple product lines including the premium Pinnacle series and budget-friendly CrownView line.
The product range covers single-hung, double-hung, casement, awning, slider, picture, bay, bow, garden, and basement windows. Lindsay partners with Cardinal Glass for insulated glass units featuring SolarBan60 Low-E coating and argon gas fill. The Pinnacle series targets high-performance applications with superior air infiltration and security ratings, while CrownView delivers ENERGY STAR qualification at entry-level pricing. All manufacturing happens in the USA with regional offices across six states.
For homeowners replacing windows, qualifying ENERGY STAR certified Lindsay products can earn federal 25C tax credits of up to $600 per year for windows. Lindsay's product lines are designed to meet or exceed ENERGY STAR requirements across all U.S. climate zones. Use QMID R3L7 on Form 5695 when filing.
