Created to deliver beauty and performance, the classic steel Model 8300 is one of Wayne Dalton’s best-insulated residential garage doors. It’s made with two layers of steel surrounding a thick layer of foamed-in-place polyurethane insulation which contribute to its impressive R-value of 12.12, which can improve your home’s thermal efficiency, cancel street noise and help the door operate quietly. Equally impressive is its thoughtful design that boasts simple lines, clean paneling with a smooth finish. Price includes: door sections, tracks, extension springs, and hardware kit.
