Frameless sliding windows from swissFineLine for optimal noise protection

Excellent noise protection

The sliding windows for acoustic comfort. Offering sound insulation of 46 dB, the swissFineLine Silence is specifically designed for use in noisy environments.

The ability to find peace and quiet within your own four walls is a key factor in your quality of life. Whether you need a relaxing night’s sleep or a few hours of focused work, swissFineLine Silence prevents outside noise from disturbing you. These sound-insulating sliding windows preserve a restorative, uncompromising tranquillity. This makes swissFineLine Silence the perfect choice in urban settings, on busy streets, and even on flight paths and beside railway lines. 

The window elements provide outstanding sound insulation (Rw = 46 dB) across the whole frequency range. That corresponds to noise protection class SK5. As a result, these sliding windows deliver noticeably better noise reduction than those of other manufacturers. The use of state-of-the-art glass technology and the elements’ flush installation to reduce the sound absorption surface area combine to deliver outstanding acoustic results.

swissFineLine Silence offers acoustic comfort even in noisy environments.

Excellent acoustic protection:

  • swissFineLine Silence offers effective 46 dB sound insulation across the whole frequency range
  • These sliding windows reduce the noise level of a freight train to that of a radio at a very low volume
  • A difference of just 3 dB means double the sound intensity for the human ear
  • Noise protection independently certified by testing institute ift Rosenheim GmbH (according to EN ISO 10140, EN ISO 717)
