The evolution of Softline 70 with triple weatherseal. 76mm, 6 chambers and Uw from 0.9 W/m²K. Our recommended system for new builds and quality renovations.
The Softline 76 is currently our preferred system for new builds and quality renovations. The triple weatherseal makes a real difference: it improves both airtightness and acoustic insulation compared to the Softline 70.
In our installations with the 76, clients notice the difference in acoustic comfort from day one, especially in homes near traffic routes. The price difference vs the 70 has narrowed significantly in recent years.
It's a system that accepts triple glazing up to 46mm, which opens very interesting possibilities for high energy-efficiency projects without needing a PassivHaus system.

The Softline 76 is the evolution of the 70 with better performance: 76mm depth (vs 70mm), 6 chambers (vs 5) and triple EPDM gasket (vs double). This means better thermal and acoustic insulation. The price is approximately 10-15% higher.
The guide price starts at around €320 for a 1-sash casement (60–90cm wide), in white with double low-E glass. A 2-sash window of 120cm costs between €430 and €590.
Both have triple gasket, but the Softline 82 adds 7 chambers (vs 6 of the 76) and is PassivHaus certified. The 82 is designed for high energy-efficiency buildings. The 76 is already excellent for conventional new builds.
The Softline 76 does not have PassivHaus certification. For that you need the Softline 82. However, the Softline 76 with triple glazing can achieve very low Uw values (from 0.75 W/m²K).
The price difference between the 70 and 76 has narrowed significantly. Given that the 76 offers triple gasket, better insulation and accepts thicker glass (up to 46mm), we consider the extra investment fully justified.
