Customization guide

Adjustable parameters:

  • Density: Opt for 30 kg/m³ for lightweight installations or 50 kg/m³ for high-frequency absorption.
  • Size: Choose from 300×300×100mm to 600×600×200mm panels to match room dimensions.
  • Arrangement: Cluster panels in grids or staggered patterns to target specific interference zones.

Get inspired

With pyramid-shaped foam panels, you can create tailored acoustic solutions for demanding environments. For example, high-density panels in anechoic chambers absorb 99% of microwave reflections, while medium-density versions reduce echo in recording studios. Their EPR certification ensures safe deployment in regulated facilities.
