Why use Dado Rails or Picture Rails?
Dado and Picture rails are usually associated with period properties, which normally feature the extensive use of mouldings. However, with colours being used in a lot more unique ways than back then, the new modern function of dado and picture rails is to provide a clear border between different colours on a wall. These products can be very effective in both modern and period interiors.
Create a border between colours or textures.
Dado and picture rails are a natural choice if your design scheme features two to three colours running in unison around a room. In these situations each rail acts a clearly defined boundary for each section of colour as the eye scans a wall.
Dado rails are also extensively used to mark where interior panelling ends and wall starts. The dado rail in this situation also adds a decorative element to the edge of the panelling instead of an abrupt finish.
