Triple layer garage doors are comprised of a steel front, thermal middle and steel back. Sometimes referred to as the “sandwich garage door,” the steel triple layer is the strongest and most durable of garage door options on the market. With heavy–duty material on the outside and inside, this low–maintenance door contains eco–friendly polystyrene thermal insides that can help boost a home’s energy efficiency. Furthermore, this conveniently soundproof door is quiet to open and shut.
