The reliability of Sigma cabins does not constitute a waiver of the necessity for regulatory inspections and regular maintenance operations. Sigma can perform renovating operations that both embellish your cabins and improve passenger comfort: this is very highly visible added value. New seats, new colours, video screens and sound-systems can transform inner comfort completely.
Besides improved comfort and aesthetics, renovating the cabins can facilitate future maintenance operations and this will reduce their costs! This is also the ideal opportunity to make functional improvements: such as better ventilation, ski-holders, etc.
