I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.
I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.- Mike
