This is what I am doing to go through the wall with my flue. I will probably use black single wall inside and insulated pipe outside. This setup will be for a wood stove temporarily to heat a large sun room until I can build an aircrete sub-floor with a hard finish on top. Then I can build a rocket mass heater. I will run the wood stove full throttle and stack concrete blocks and sand to hold heat to help prevent creosote.
Any ideas or comments are welcome.
Thanks
