Hi, all:
What might be causing chimney (metal flue) banging sounds during wind gusts? July 2020 professional install of a pre-fab wood burning fireplace (flue construction pictures are below). We had a very windy day here, and with every strong gust the chimney would make a banging sound like this (fireplace was not in use at the time - damper was closed):
In retrospect, this was going on for some time, but I was never really able to pin-point the source until now and banging was much more muffled before. Appreciate any info. TIA!!
