Yes. The 88 MD is certified by the Passive House Institute. With 88mm, 6 chambers and triple gasket, it achieves Uw of 0.8 W/m²K. It's Kömmerling's top-performance system.
The guide price starts at €400 for a 1-sash casement. It's a premium system, but the investment pays for itself in long-term energy savings.
Both are top-level PassivHaus systems. The Veka 82 achieves slightly better Uw (0.7 vs 0.8). Where the 88 MD wins is in Full Cover finish and frame depth (88 vs 82mm).
The Cortizo A 84 achieves Uw 0.66 vs 0.8 for the 88 MD — better insulation. Cortizo offers the Hidden Sash and is more affordable. The 88 MD has Full Cover and 125 years of tradition.
For passive houses, nZEB buildings, bioclimatic homes and high-end renovations where maximum energy efficiency is a priority. Ideal for cold zones and large glazed surfaces.
