I hope you can advice me on the best/safe way. I need to pass a single
walled pellet stove pipe though a mez floor made of plasterboard and wood
then on though a slopping roof made of plasterboard insulation then roof tile.
Would it be ok just to pass the pipe though with clearance and then use
trim/rose ring to cover the gap? or is there a better way to do this
with single skin pipe?
