Hunter Douglas offers roll formed or extruded aluminium panels for open façades. Roll formed panels are coil coated with a superior UV and scratch resistant Luxacote® paint system that is available in a wide range of colours. Luxacote(R) is a powerful 3-layered system consisting of an Anorcoat pretreatment, a PU-based colour coating and a transparent topcoat for added durability. The inside of the panels can be white for improved light reflection or be the same colour as the outside. Extruded panels can be anodised in a natural silver colour or a range of alternative colours and shades. Anodisation is an electrolytic process that turns the top layer of the aluminium itself into a strong protective surface that is resistant to all conditions. For an even wider choice of colours, extruded panels can be powder coated in the full range of RAL colours or specified to a designers specific colourway.
