Classic Steel Model 8300 is one of Wayne Dalton’s best-insulated residential garage doors and is durably made with two layers of steel surrounding a thick layer of foamed-in-place polyurethane insulation. These doors are offered in five classic and contemporary designs and a wide selection of painted and bi-directional wood grain finishes.
Model 8300 comes with an impressive R-value* of 12.12, using polyurethane foamed-in-place insulation, which can improve your home’s thermal efficiency, block street noise and make the door operate more quietly. Heavy-gauge steel wrap around end caps trim-out door edges for better appearance, improved strength and damage-protection of the insulation.
