Chimney Liner Insulation

Hi All,

I am having some condensation at my gas furnace flue exhaust pipe. The existing flexible liner is not insulated and when the hot exhaust air hits the cold air within the liner, condensation drips at the adapter where the furnace flue meets the liner.

I am planning to do this project myself. I am wondering if I am able to remove the existing flexible liner (no holes, cracks, or damage,) insulated it, and reinstall it, or if I will need to install an entire new liner itself. Another option would be packing the chimney with vermiculite, but a liner blanket seems like the better option.

Any ideas & advice are welcome!

The existing flexible liner
Hopefully this is not dryer duct it's not approved for flu pipe and as always should be minimal, solid pipe is best.!

They sell kits!
