Classic Steel Garage Doors with Exceptional Thermal Efficiency

Designer style and enviable thermal efficiency go hand in hand with Wayne Dalton’s Classic Steel garage doors. It doesn’t matter what part of the country you live in, whether you experience extreme cold or extreme heat in your region, better thermal efficiency is on everybody’s mind. That’s why we’ve created two Classic Steel garage doors designed to improve your home’s thermal efficiency—Models 8300 and 8500.

Our best-insulated residential garage doors feature two layers of steel surrounding a thick layer of foamed-in-place polyurethane insulation. But along with delivering great thermal efficiency, our Classic Steel garage doors boast great looks, too.

Features

These Classic Steel Garage Doors Have It All

Our Classic Steel garage doors are engineered for superior performance and gorgeous, easy-care living. High-end features make them:

  • Resilient
    Heavy-gauge steel wraps around end caps and door edges for a better appearance, greater strength and to protect polyurethane foamed-in-place insulation. Silent glide nylon rollers with solid steel shafts ensure your classic steel garage doors will provide years of smooth, quiet, dependable operation. Wind load options with structural reinforcements are available for coastal areas and high-wind areas.

  • Thermally Efficient
    While Model 8300 features an impressive U-factor of .15  (R-value of 12.12), Model 8500 is our highest insulated residential garage door with a U-factor of .12  (R-value of 16.22) thanks to polyurethane foamed-in-place insulation. Our quiet Classic Steel garage doors can help improve your home’s thermal efficiency and block street noise. Snug tongue-and-groove section joints reduce wind and keep weather from entering the garage.

  • Durable
    An upgrade to the optional 25,000-cycle spring delivers more than twice the life of a standard torsion spring.

  • Guaranteed
    Our classic steel garage doors come with a Limited Lifetime Warranty.

Available with WindSafe® wind load reinforcement built to withstand specific high-wind pressures to meet local building codes.

*Proper door selection is the responsibility of the homeowner. Please consult your local building code official, certified engineer or architect for wind load requirements in your specific location.
