The Kömmerling 76MD profile system is designed for the production of modern windows and doors with unique functioning parameters. Outstanding energy efficiency values make it possible to use the Kömmerling 76MD profile system for the manufacture of windows that will be installed in private houses, cottages and apartments with high-quality thermal insulation. An additional centre seal contour minimizes the risk of drafts and reduces heat loss even in severe frosts. In addition to high thermal insulation performance, the advantages of Kömmerling 76MD include excellent sound insulation and resistance to break-in attempts. The rigid multi-chamber profile well restrains sound waves, and outstanding mechanical qualities make it much more difficult to attempt a force break. The enlarged light aperture is another argument in favor of the Kömmerling 76MD . Profile proportions increase the amount of natural light entering the room — while fully preserving the other advantages.
