Greenfelt

what it does
It reduces impact sound at the source while lowering the reliance on virgin fossil materials. You don’t add it later. It is part of the flooring system.

• integrated into the structure
• made from recycled PET
• designed for intensive commercial use

Acoustic performance without adding extra layers or complexity.

acoustic performance
Greenfelt is built to control sound where it starts, at the floor.

• impact sound reduction: 19 or 22 dB (ISO 10140)
• sound absorption: Class E (Δw = 0.15)
• walking noise: ~71 dB

impact sound reduction : 19 or 22 dB
This is about noise travelling to adjacent spaces. Think: footsteps transmitted to the floor below. Greenfelt reduces structural vibration before it enters the slab.

• less noise between floors
• reduced disturbance in multi-level buildings
• better acoustic separation

sound absorption : class E (Δw = 0.15)
This is about noise inside the space. Hard surfaces reflect sound. That creates echo and increases overall noise levels. Greenfelt absorbs part of that energy at the surface.

• lower reverberation
  
• clearer speech
  
• more comfortable environments

walking noise : 67 or 71 dB
This is the direct sound you hear when someone walks on the floor. Not transmitted, not reflected. Immediate. Greenfelt softens that contact sound.

20 people walking on ntgrate flooring create the same noise as 1 person on hard flooring.

• less intrusive footsteps
  
• quieter circulation areas

recycled content
Greenfelt also represents a material shift. The material composition evolved. At the same time acoustic performance improved.

• 2020 → 50% recycled content
  
• 2022 → 90% recycled content
  
• 2024 → 93% recycled content
