I would be grateful for any input on the best way to soundproof a noisy flue pipe that runs vertically through a corner of my bedroom. I know it's not an audio/visual issue but I was hoping to draw on the acoustics expertise in this forum. The pipe is the boiler exhaust flue pipe which runs through the house up to the roof and makes loud banging noises (loud enough to wake us up in the middle of the night) due to thermal expansion/contraction every time the heat turns on or off.
Currently, the pipe is enclosed in a drywall chase. Due to its location in the corner right next to a window, there is extremely limited space in which to add sound insulating thickness (hence my dilemma) -- see the attached photo and diagram. There is less than an inch of space between the pipe and the window moulding.
My current plan is to take down the drywall enclosure, stuff in as much mineral wool batting as I can fit into the cavity around the pipe, then rebuild the enclosure using 1/2" QuietRock drywall. If it can fit, I would add a second layer of QuietRock with Green Glue in between the layers, but I don't think there is sufficient room between the pipe and the window moulding for a double layer.
Would this work? Are there better ways to go about this? I'm willing to spend whatever it takes (given that our sleep is at stake) but the space limitations seem to be my biggest impediment to achieving meaningful noise reduction.
Thank you so much for any feedback.
