An internal wall that carries load. The build-up is a mass–spring–mass arrangement with two decoupled Omega channels, which is the arrangement used where airborne sound transmission between dwellings matters. The intended applications below follow from that geometry — they are not a performance claim, and no acoustic figure is stated for this detail until a laboratory test report exists.

| U-value, bridging corrected | 0.45 W/m²K | EN ISO 6946, one-dimensional steady state, with a +20% bridging correction applied as an engineering estimate. |
| Self-weight | 91 kg/m² | Mass estimate from the layers and dimensions in the source document. |
| Traditional equivalent | 239 kg/m² | Derived from the published self-weight and reduction percentage. |
| Weight reduction | 62 % | Self-weight against the traditional equivalent build-up. |

U-values are one-dimensional steady-state calculations to EN ISO 6946. Bridging correction is applied as an engineering estimate: +20% for walls, +15% for horizontal elements. 2D numerical analysis to EN ISO 10211 is in progress; values will be updated on completion.
