📊 Compare with other solutions
To achieve R = 7.527 m²·K/W, other materials would require:
-
Mineral wool: ≈ 27.3 cm
-
Cellulose: ≈ 28.6 cm
-
Wood fiber: ≈ 28.6 cm
-
Open-cell polyurethane foam: ≈ 28.6 cm
System 10 Premium+ achieves the same performance in just 15 cm — that is, half the space needed by conventional insulation.
