The decorative louvers are manufactured by cutting and shaping a stove enameled pre-paint aluminium sheet. Consisting of a U-profile, with T-bar = 15 mm and height = 38 mm, they are assembled as edged panels on the module and are integrated into the visible substructure (15 mm T-bar), whereby they hide the non-enameled sides and compensate the thickness.

Removable by simply pushing up manually, they allow access at any time to the plenum space; once in place, the ceiling has the uniform aspect of a louvered ceiling with integrated main runners.
