For most homeowners, Clopay is the better choice if you want the widest design selection and the most advanced insulation, while Amarr is better if you want stronger structural steel at a lower price. Clopay leads on Intellicore polyurethane insulation up to R-20, the largest catalog of styles, and premium lines like Canyon Ridge faux-wood and Coachman carriage house. Amarr leads on thicker steel gauges, the SafeGuard pinch-resistant panel system, and excellent value through Costco. Clopay tends to cost 10 to 25 percent more for a similarly equipped door. Pick Clopay for design flexibility and energy efficiency. Pick Amarr for durability, the Classica carriage look, or if you want a quality door at a lower price.
