How about a Stove Pipe Heavy 24 Gauge Collar Trim Ring. Check Ebay.

Unless it's a vent from a convection style oven or pizza oven, the pipe will never get much more than warm to the touch.

Foam will do the trick. Cover the outside with a flange.
We bought a rather expensive restaurant quality exhaust hood.
The duct is plastic so obviously heat is not an issue.

Keeping the pipes clean is the issue, not the heat.
Similar to dryer vent fires. It is the lint that is the issue, not the heat from the dryer (which is probably hotter than the heat from the exhaust vent which is "diluted" with room temperature air.

It shouldn't get hot. In a missionary wall? I'd use a neutral colored mortar for a clean finished look.
