Total performance for 10 cm rafters
Isoflect System 10 — Compact solutions with proven efficiency
When the space between rafters is limited to just 10 cm, most conventional insulation can no longer deliver the performance an energy-efficient home needs.
The Isoflect System 10systems, however, achieve impressive thermal resistance values thanks to a smart combination of Isoflect Wolle technical wool and specialized thermo-reflective membrane layers.
🔬 Thermal performance — for all 6 available recipes
| Configuration | R (m²·K/W) | U (W/m²·K) | λeq (W/m·K) |
|---|---|---|---|
| System 10 Premium+ — with Wolle P2100 | 6.211 | 0.161 | 0.025 |
| System 10 Premium — with Wolle P2100 | 5.986 | 0.167 | 0.026 |
| System 10 Medium — with Wolle P1500 | 5.911 | 0.169 | 0.026 |
| System 10 Medium+ — with Wolle P1500 | 5.911 | 0.169 | 0.026 |
| System 10 Base+ — with Wolle P800 & P2100 | 5.527 | 0.181 | 0.027 |
| System 10 Base — with Wolle P800 & P1500 | 5.082 | 0.197 | 0.028 |
🔎 All values are calculated for real configurations, with Isoflect Wolle insulation installed between 10 cm rafters and completed with the Isoflect thermo-reflective membrane package, according to each recipe.

📊 Comparison with other materials
To achieve the same R ≈ 6.211 m²·K/W value, other solutions would require:
-
Mineral wool: ≈ 22.6 cm
-
Cellulose: ≈ 23.4 cm
-
Wood fiber: ≈ 23.6 cm
-
Open-cell polyurethane foam: ≈ 23.6 cm
Isoflect System 10 Premium+ achieves this performance in just 10 cm — with no loss of usable space and no compromises.
