Up to now classical air diffusers were always associated with the colour white. Trox has broken with this tradition. More decorative paintwork now provides architects with additional design freedom. Colours and textures beyond the RAL scale can now be burned into the surface of the air flow passages. For example marble and wood textures can be simulated in all colours. This allows an almost unnoticeable integration of ventilation systems in wall, ceiling and floor constructions. Decorative paintwork is also characterised by its high mechanical stability and by its resistance against solvents and chemicals.
