The façade build-up, and the detail the rest of the system is judged by. Eight layers run from the Pladur lining to the monocapa render across a total of 228 mm. What makes it different from conventional light steel framing is layer 7: 50 mm of INSULTERM 600 sprayed on the outside face of the Placner sheet, continuous across the whole façade. In conventional framing the studs bridge the full wall thickness and a cold line runs through the envelope. Here the studs stop at the Placner sheet and never reach the outside face.

Tabla de capas
| Capa | Material | Espesor | λ | Función |
|---|---|---|---|---|
| 1 Pladur | Gypsum board | 13 mm | — | Internal finish Thickness from the D.02 section sheet supplied by the client on 2026-09-09 ("Pladur (13 mm)"), which was not in the original transcription. See docs/OPEN-ITEMS.md item 3. |
| 2 Perfil Ω | Cold-formed galvanised steel | 15 mm | — | Fixing profile for the internal lining Layer added from the D.02 section sheet supplied by the client on 2026-09-09 ("Perfil Ω (15 mm)"), which the original transcription omitted. It is what closes the build-up to 228 mm. See docs/OPEN-ITEMS.md item 3. |
| 3 INSULTERM 600 en la cámara | Sprayed thermal-acoustic conglomerate | 90 mm | 0.138 W/m·K | Cavity insulation with mass, warm side |
| 4 Lana de roca en la cámara | Rock wool | 50 mm | 0.039 W/m·K | Cavity insulation, cold side — where the temperature gradient is steepest λD 0,039 W/m·K from the ISOVER Alphatoit datasheet (FT_Alphatoit_ES, 14/03/2024) supplied by the client on 2026-09-09, to EN 12667 / EN 12939. The same sheet declares RD 1,25 m²·K/W at 50 mm. The published U-values for this detail are unchanged — they come from the source document's own calculation and were not recomputed. See docs/OPEN-ITEMS.md item 29. |
| 5 Perfil de acero C 140 | Cold-formed galvanised steel | 140 mm | — | Structure — the cavity contains layers 3 and 4 |
| 6 Placner | Cold-rolled galvanised steel, Z200, 0.3 mm base sheet | 5 mm | — | In-plane racking bracing · mechanical key for the sprayed layer 5 mm is the overall profiled depth including rib height, not the sheet gauge. |
| 7 INSULTERM 600 | Sprayed thermal-acoustic conglomerate | 50 mm | 0.138 W/m·K | Continuous external thermal break — the studs never reach the outside face |
| 8 Monocapa | Single-coat mineral render | 5 mm | — | External finish Thickness from the D.02 section sheet supplied by the client on 2026-09-09 ("Monocapa (5 mm)"), which was not in the original transcription. See docs/OPEN-ITEMS.md item 3. |
| Total | 228 mm |
Una raya indica que el documento de origen no declara ese valor; no es un cero. Las capas contenidas en la cámara van sangradas: van dentro del canto del montante, por lo que la columna no suma el total.

Las transmitancias son cálculos unidimensionales en régimen estacionario según EN ISO 6946. La corrección por puentes térmicos se aplica como estimación de ingeniería: +20% en muros y +15% en elementos horizontales. El análisis numérico 2D según EN ISO 10211 está en curso; los valores se actualizarán al completarlo.

Dónde se usa
- External envelope walls to residential, hotel and healthcare buildings
- Load-bearing façade panels on C140 studs
- Coastal and marine-exposed sites, specified with Z275 Placner
Notas de diseño
- The external INSULTERM 600 must be continuous across floor and roof junctions. Any discontinuity forfeits most of the advantage the detail is built to deliver.
- Z275 Placner is specified as standard for coastal and marine-exposed sites. It is available in the same profile.
- In subtropical and Mediterranean climates the vapour behaviour of the Placner sheet is not a concern. For continental heating climates, hygrothermal analysis to EN ISO 13788 / EN 15026 is required before specification — Solid System will supply it on request.
- INSULTERM 600 and mineral wool sit inside the 140 mm stud cavity, not in addition to it. Read sequentially the layer labels over-total the wall; the dimension line is correct.
