Surface mounted doors, also known as surface sliding doors or barn doors, are a versatile door solution that slide along a wall-mounted track, rather than disappearing into a pocket or swinging on hinges. The door hangs from rollers attached to a track mounted above the doorway, allowing it to slide parallel to the wall. This system provides a space-saving, functional, and aesthetically pleasing alternative to traditional hinged doors.

Surface mounted doors are commonly used in residential and commercial spaces, including living rooms, bedrooms, offices, and restaurants. They serve as room dividers, closet doors, or entrances to en-suite bathrooms, adding a rustic, industrial, or modern touch to the design depending on the chosen style and material.

The history of surface sliding doors, often associated with barn doors, dates back to agricultural settings where their simplicity and durability were essential. In the 19th and early 20th centuries, these doors provided easy access to large, weatherproof storage spaces in rural buildings. Over time, surface sliding doors have been adapted and repurposed for residential and commercial interiors, embracing various design aesthetics.
