Pyramid-relief PET tiles bring directional shadow play to walls and ceilings. Made from the same 100% polyester fibre body as the flat panel family, they keep the published 9 / 12 mm acoustic data while adding sculptural depth.

Can I combine pyramid and hexagon?
Yes — mixing reliefs on one wall is a popular treatment.
Is it tackable like flat PET?
Yes — the felt body accepts push pins.
Does routing reduce absorption?
Marginally at most; the relief adds useful scattering.
Clear sound, clear mind.
