Indow Acoustic Ratings
The Acoustic model differs from the standard model in that its intent is to block more of the exterior sound from entering the home. These are often referred to as sound proofing windows, although in this case they are inserts that go on the interior of your existing window. While the standard Indow insert blocks some 50% more noise than with just a single pane window, the acoustic series is said to block some 70% of all external noises. Therefore, Indow windows STC should be close to 35 to 37 in the Acoustic option.
This model is ideal for individuals or families who live in a more urban neighborhood or on a busy street where noise and exterior sound is a noticeable issue. The Acoustic window does not look or function any different from the standard endow insert. There are no additional steps that the consumer or the installation company has to take in order to place the acoustic model in the home.
