And the winner of the Golden Bag 2012 is... the PREFA FX.12 roof and façade panel

Aluminum roof and facade panels Prefa FX.12 are unique due to their irregular surfacebreaks, which allow for the creation of a futuristic design for modern roofs or facades. FX.12 thus provides a different perspective from every angle thanks to an endless play of light and shadows. To maintain the irregularity of the surface, each FX.12 panel is unique right from production. Light breaks in the surface do not repeat, resulting in irregularities even on large areas. In addition to its individual optical appearance, it offers a range of practical advantages in processing - meeting all the demands of both modern and traditional metalworking trades.
