Maintenance-free aluminum doors and windows offer a wide variety of colors and are virtually maintenance-free and resistant to external influences. This thermally isolated system is ideal for those who prefer a mid-range insulation.
As aluminum conducts heat and cold, Skyprof offers the thermally improved S65 aluminum window and door series. A heat barrier is used in this system to thermally separate the inner and outer surfaces.
