Garage doors can be made out of many materials, but steel, aluminum, wood, and vinyl (polyethylene)
are the most popular materials.
A few manufactures like Trotter Doors are making energy efficient garage doors by putting
foamed-in-place polyurethane insulation in the steel door.

A common material for a new garage door is roll formed steel sheet to look like a raised panel wooden door.
Steel doors are available in uninsulated, insulated, and double skin steel.
 A design mimicking carriage house doors has become quite popular since about 2002,
 and many manufacturers clad the exterior of a steel door with composite, vinyl boards,
or DecamTrim to give it the appearance of wood. Steel carriage doors are becoming
the most popular carriage door due to weight of the door, no rotting, and a large
amount of designs. A more economical alternative for garage doors is steel stamped construction.
