Skylux iWindow series: a top choice for sound insulation

The Skylux iWindow series is known for its excellent sound insulation. With an Rw value of 39% for the Skylux iWindow2 and even 41% for the Skylux iWindow3, these flat roof windows are the best choice for those looking for sound reduction. The combination of a glass window with HR++ insulating glass delivers the best results.

Other options and considerations

Although the Skylux iWindow series represents the top of the market, the iDome and multi-walled skylights such as the five-walled skylight also offer good sound insulation. Keep in mind that single-walled skylights are not suitable for sound reduction and that the material of the skylight plays an important role.

Conclusion: the best choice for sound insulation

For those who hate the annoying tapping during a rain shower or noise pollution from outside, sound insulation is an essential aspect to consider when choosing a skylight. The Skylux iWindow series, especially the Skylux iWindow3, is at the top when it comes to sound reduction. The right combination of glazing, size, and thickness of the curb can further contribute to a quiet and comfortable living environment.
