Residential garage doors are vertical sliding doors, typically automated with a remote, that enhance home security and curb appeal while providing convenient access to your garage. They are available in various materials like steel, wood, vinyl, fiberglass, and aluminum, with styles ranging from classic raised panels to modern glass or sleek flush designs. Key considerations include their operation (manual or automatic), insulation for energy efficiency, material choice for durability and aesthetics, and installation for seamless performance.
