OVERVIEW
The O2 arena's roof needed state-of-the-art acoustic engineering to eliminate virtually all nuisance ambient noise (bass thumping) outside the arena contributing to fantastic acoustics inside the structure.
The complex roof design featured several layers of different density barrier materials to deaden even the lowest bass frequencies, all carried on special acoustic deck structures.
The structural deck troughs were filled with ROCKWOOL RW4 insulation, with ROCKWOOL Acoustic membrane over and a 50mm Rigidal intermediate deck.
