Fire barrier around flu?

In the process of remodeling I noticed that the "fire stop insulation" between the two floors around the flu was almost non-existent, what can I use to replace it?

Hi Scott. In my work we try to block the air flow using sheet metal and high temp silicone sealant. There are fire rated insulation, but I'm not sure what the codes will allow.
