Mesa's Carriage Overlay Series garage doors offer a luxurious appearance and are a hybrid garage door. Using our insulated sandwich construction, Platinum Series flush steel door sections; we apply precision cut Extira® composite wood overlay designs to create the largest selection of carriage style designs in the industry. These doors have an insulation value of 10.4 R, a Thermal Barrier Joint and are factory painted after assembly. Unlike other overlay doors the Carriage Overlay Series maintains uniform dimensions of the overlay components regardless of the door size. Over height and odd width doors are just as attractive as standard sizes.
