Along with sound absorption, the impact resistance of construction materials is an important issue in schools and gyms. Ceilings in these kinds of areas need to be able to withstand tougher-than-average wear and tear as well as frequent demounting.
The impact resistance of suspended ceilings is tested according to EN 13964:2014 annex D and evaluates the total ceiling system (tiles and all grid components). It defines three impact resistance classes:
- Class 1A ceilings should be installed in any sports hall where heavy-impact ball sports are played.
- Class 2A ceilings can be installed in sports centres where low-impact ball sports are played and in heavy-duty school areas.
- Class 3A ceilings can be installed in rooms where the ceiling must fulfil basic requirements on impact resistance e.g. classrooms, school corridors.
The test procedure for impact resistance indicates the ability of a ceiling to resist the incidental impact of balls under normal conditions in sports halls.
Rockfon Boxer ceilings feature a reinforced surface giving them superior mechanical resistance. The Rockfon System OlympiaPlus A Impact 1A provides best in class impact resistance.
