CARRIAGE HOUSE garage doorS
types of CARRIAGE HOUSE DOORS
non-insulated Garage Doors
Non-Insulated garage doors are stamped from a single sheet of 25/24 gauge steel. These are usually the most economical of all steel doors.
insulated garage doors
Insulated garage doors have a steel skin on the outside with a thick layer of polystyrene as a backer covered by a layer of vinyl. The backer provides soundproofing and additional insulating value to the door.
Steel-Back 3-layer garage doors
Steel-Back 3-layer garage 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. These are also available with thicker insulation for greater R-value (a measure of thermal resistance).
