My first post here, so thank you for helping!
I've purchased a wood stove and I need to pass the pipe through a 15cm external, insulated wooden wall of a cabin.
I've found this method which seems affordable and safe. I don't have a big budget for pre-made solutions, but I am very handy so I don't mind building a DIY solution.

Essentially, it involves building a fireproof box of non-combustible insulation board to provide clearance around the insulated pipe as it passed through.
Is this generally a good idea?
Should it be filled with rockwool
