The low profile height of the sashes and frames, which is only 118 mm, allows maximum illumination of the rooms thanks to the larger glass area. Softline profiles allow the installation of insulating glass units with a thickness of 6 to 42 mm, and with the use of an additional element even up to 49 mm. With the right glazing package and proper installation, windows with Softline profiles meet Class 6 sound insulation requirements, attenuating noise up to 50 dB, making them ideal for buildings near busy roads. In addition, the glazing package’s installation depth of 21 mm makes the windows less prone to dewing, which also increases their resistance to forced entry.
