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.


































































































In addition to insulation, our doors have a bottom weather seal. The bottom weather seal blocks drafts and reduces air infiltration. It remains flexible even in extreme cold to keep the bad weather outside. All of our residential garage doors feature a bottom weather seal.
