ALUMINUM DOORS
Aluminum doors, like steel units, use an insulation core covered by a metal skin. Unlike other door systems, however, aluminum versions are sold exclusively through dealers. Each is custom-built to your opening.
Manufacturers offer all types of options. The doors in the Armaclad line from Hess Manufacturing, for example, come in dozens of styles and colors, with smooth or wood-grain finishes.
Aluminum doors have a baked-on enamel finish, so they never need painting and won't rust — which explains the 20-year warranties that are common. You can also match the color and style of your door with an aluminum storm door. All these benefits don't come cheap, however. At prices that start at about $600, aluminum doors are the most expensive choice after solid wood.
