The wall duct panelling system with demountable panels is a solution to gaining access to vital plumbing items in bathrooms, such as piping and toilet/urinal cisterns, that are typically hidden behind a wall facade. As well as looking modern, these ducting panels provide a clean, professional design solution for both toilet and urinal situations. The demountable panels can be made in either full height or low level duct designs and are compatible with all types of sanitary ware. This system is available in an extensive range of 13mm and 18mm board products.
