I was debating on putting this in the Acoustics Circle but figured this might be a better place...
I am looking for a good and solid adhesive, spray or paste or other, that can adhere some Auralex acoustic foam to the inside of a rectangle metal air return duct...
What I am needing to do is quiet a large air return vent to the HVAC, that is on the hallway wall, up at the ceiling,outside my office door at home. I had a knowledgeable HVAC guy come and check out the system, for various things, I pointed this out to him, he checked the system for proper air-flow first and said I could adhere a section of foam to the end/top and backside of the metal vent path to quiet down the velocity noise I hear at my desk. He said this will not hamper airflow if I keep the foam piece to a certain size and dimension we discussed.
So I need a good solid hold adhesive that will not break down and cause the foam to fall down the return vent... Any product suggestions?
Thanks
Jason
