Default Why use a chimney liner?

What is the benefit of using an insulated or refractory chimney liner?

It's just that I see a lot of builds where people have gone to a lot of trouble to build a nice sturdy brick vent and then put a steel chimney on?

Is there any reason not to just lay 5-8 courses of bricks on top of the vent to make your chimney?

cheers,
Mitch.

Mitch
Your suggestion would work just fine...insulated chimneys would tend to draw better but, on what is such a short run it probably does not make much difference...most likely it just depends on how you are going to finish your oven and where it is located I suppose...

A liner is typically refractory material made to take the exhaust heat.

Might? also be recommended or required for any indoor type installation.

Insulated pipe tends to get hotter and you will have less creosote build up too. It's usually required when passing though a wall or ceiling.

Not sure that either is needed in an outdoor oven installation.
