Tiles have a high impact resistant surface, especially suited for areas with a high activity level e.g. schools and sports halls.

The sound absorption level is exceptional; thereby contributing to a good acoustic environment in what typically can be noisy application areas.

For maximum impact resistance use with Rockfon System Samson . In areas where the requirement for impact resistance is lower, Samson can also be installed in RockLink 24 with clips or retaining channels.
