Filigree design for healthy living

The Soundline M box window from Solarlux is an innovative solution for increased sound insulation in urban living situations. It was specifically developed to meet the requirements of healthy living and designed for use on windows in new builds and renovations. The Soundline M system was designed and tested by SG-Bauakustik in collaboration with the engineering firm IfB Sorge, a specialist in building physics. With the attached module, increased sound insulation of up to 20 dB compared to the simple standard window can be achieved. In addition, the box window impresses with its raised thermal insulation and elegant , delicate appearance.
Solarlux holds a patent for the Soundline M: Patent pending No. 10 2025 132 544.
