TOP-90 SOUND dome rooflight double-skinned + LSG 8mm

Sound insulation which protects and provides daylight

It can very quickly get loud inside production facilities. This is why VELUX Commercial has developed the TOP-90 SOUND so that no problems arise when using dome rooflights.

This enables you to comply with the officially prescribed limitation values for sound imissions and, at the same time, reduce sound emissions. This is thanks to the special design and construction with an 8-mm LSG disc inside. In this way, the dome rooflight also fulfils the requirements of the EnEV (Energy Saving Ordinance).

The TOP-90 SOUND is not only suited for use in new buildings but also in refurbishments. Youalso have the selection of a wide range of accessories, such as sun protection or insect protection.

An upgrade to SHEV (LBO) and for a ventilation system can also be implemented with the corresponding accessories. As such, the dome rooflights can be individually adapted to all your respective project requirements.
