The 140x18mm Bullnose MDF isn’t meant to disappear into the background. With 140mm of height to work with, it’s a natural size to consider when taller skirting suits the room better than a small board. The bullnose detail rounds off the edge, keeping the profile fairly simple despite its size. At 18mm thick, there’s also enough depth for the board to feel in proportion with its wider face. This can work particularly well in larger living areas, hallways or renovation projects where broader mouldings already exist. Before ordering, run a tape around the room and check doors, cabinetry and any other spots where the taller board needs to finish.
