Woodstove Pipe thru cathedral ceiling

I need to run a woodstove pipe through a cathedral ceiling to the outside and have never done this before. So, I’m looking for some advice on particular methods/products.
The stove is in a small cabin with a cathedral ceiling and exposed timber rafters. The pipe will pass through the living space, between the rafters and through the interior sheathing (shiplapped pine), through a 12″ cavity of dense-packed cellulose, then through the exterior sheathing (1/2″ plywood), and out the metal roof.
Does the pipe need some sort of structural support as it passed through the ceiling (MetalBest has a product thats a double-walled pipe with metal “wings” that screw into joists or blocking)? If so, what products to people recommend (particularly, whats cheap?)?
How can I isolate the pipe from the dense-pack cellulose around it (which hasnt been blown yet)? Some sort of shield?
Thank you,
Dan

cathedral ceiling box
The manufacturer will typically have a box that goes all the way through the ceiling and up to the sheathing. The part above the sheathing is cut down the corners and folded onto the roof deck, and nailed. The box will be rated for insulation, framing, etc. contact on the outside.
