Good in the mixing spot because you dont have as much bass (or any for the sound that hits the window) reflecting back out of phase. But that just means that its going some where else. In your case its going outside to where your neighbors can hear it. Thats a bad thing. In my studio its going directly into the tracking room. Althought two glass windows helps that its still not perfect.
So as long as you dont have your neighbors complaining its probably not a bad thing.
Im predicting that it only reflects as low as 1KHz. Coefficient charts say it reflects the same down to 125Hz. But that doesnt mean its being reflected back into the room. Its not thick enough for that. Its just passing straight through and reflecting it on the other side.
