Galvanized sheet metal for fire barrier - InterNACHI®️ Forum

I’m trying to decide how I feel about this somebody installed galvanized corrugated metal around the fireplaces probably to act as the non-combustible material however it’s so thin I could probably cut it with a really good pair of scissors. The metal is not combustible however there’s nothing there to stop heat transfer through it. Thoughts? As a side note which I’m going to research later tonight this fireplace has the world’s tallest chimney.
