Steel garage doors are usually more economical than wood doors and are the most common type of garage door. Most manufacturers offer several colors out of the box. You can also paint the door to match your home. There are three distinct types of steel doors to choose from:

 

  • Single-layer doors are stamped from a single sheet of galvanized steel. These are usually the most economical of all steel doors.

  •  

  • Double-layer steel doors have a galvanized steel skin on the outside with a thick layer of either polystyrene or polyurethane as a backer. The backer provides soundproofing and additional insulating value to the door.

  •  

  • Triple-layer doors are constructed of the same materials as double-layer doors with the addition of a galvanized skin on the inside to protect the polystyrene / polyurethane from damage. The additional layer of steel makes triple-layer doors the strongest, most secure and most soundproof of all garage doors.
