Models 8300 and 8500 Classic Steel Garage Doors
Classic Steel Models 8300 and 8500 are Wayne Dalton’s best-insulated residential garage doors and are 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.
While Model 8300 comes with an impressive R-value* of 12.12, Model 8500 is our highest insulated residential garage door with an R-value of 16.22 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.
