Expanded polystyrene acoustic diffuser PYRAMID®

PYRAMID is a model that combines diffusion and absorption qualities it was devised for the acoustic music industry to enable different acoustic characteristics with the same aspect. This design was based on a quadratic format with flat absorption surfaces made of acoustic foam and on curved diffusion surfaces made of EPS which give it a superior balance, aural and visual performance. The original PYRAMID(PYR060), made on EPS and Acoustic Foam combines hemispherical acoustical diffusion and absorption in the same panel, and therefore the most balanced element from ATP's catalogue. There is other option; the PYR060E that is a diffusor made of EPS. These 2 options were designed to be applied, glued on walls and ceilings, on the modular or continuous applications, it is allowed to set on T-Ceilings as well. Average diffusion: 0.45/m2 [>500Hz;250Hz;<10KHz] Fire resistance: Regular Foam - Euroclass B-s3,d1 (similar to old M1); EPS - Euroclass B-s3,d1 (similar to old M1) Finished with an ecological paint (only PYR060E model) Very easy to install
