The Solatube® Ventilation Add-On Kit features an in-line fan motor assembly that is remotely mounted in the attic or plenum rather than on the ceiling of the room to be vented. This significantly reduces the noise level in the room below.
At this time, there are no sones (sound) level test standards available for this product due to the number of variables involved with its installation, such as:
- Type of duct
- Length of duct
- In-line fan motor assembly distance from intake source
However, it is generally accepted that remote-mounted venting is usually quieter than in-room venting.
