Acoustic absorption property:    
absorcion acustica
Absorption with a Solid Panel of Mineral Glass Wool: Possibility of increasing the level of a false ceiling’s acoustic absorption with a solid panel of mineral glass wool, or mineral stone wool, with a film or acoustic cover on one of the panel’s faces.

Lacquered Coil-Coating: Process of continual painting, meeting all ECCA (European Coil Coating Association) rules and regulations. The paint used is polyester-polyamide with thickness of 15-22 microns applied continuously and oven-dried. It is a pre-lacquering system (the process is carried out prior to formatting the tray).
