| Material | 100% expanded cork (ICB) and granules — agglomerated with natural resin |
| Density | ICB ≈ 100–120 kg/m³ (REV ≈ 140–160 kg/m³); Granules ≈ 65–80 kg/m³ |
| Thermal conductivity λ | ICB ≈ 0.037–0.040 W/m·K; Granules ≈ 0.045–0.050 W/m·K |
| Vapor diffusion μ | ICB ≈ 7–14 (vapor permeable) |
| Compressive stress at 10% | ICB ≥ 100 kPa (depending on product type) |
| Reaction to fire | Euroclass E (system build-ups can achieve different classes) |
| Service temperature | ~ −180 °C … +120 °C (depending on detail) |
| Notes | Dimensions/thickness and standards vary by project and product family. |
14 cm concrete + 7 cm granule lightweight concrete + 4 cm screed → Ln,r,w ≈ 62 dB (sample system).
* Values are typical; final performance depends on project, granule size, placement/mix density and details. Approved system sections are available on request.
