Acoustic insulation has more and more importance in European regulations regarding self-supporting dismountable interior partitioning, and also comfort, quality of life at work, concentration and confidentiality are partly tied to good insulation and soundproofing.

The Urmóbile systems have recently achieved (12/11/2004) a certified classification of 49dB (ISO 717-1 scale) in a measurement of acoustic insulation of construction elements to aerial noise according to the UNE-EN ISO 140-3 standard.

At present this classification of acoustic insulation is the highest known regarding self-supporting, dismountable steel partitions of standard commercial pattern.
