Default What is best material to make a vent hood?

I have read the threads on ventilation, but I haven't seen a discussion on what is the best material to use to construct a ventilation hood. I assume a vent hood needs to be made of a noncombustible material, but beyond that, what are the pros and cons.

Cement board: easy to find, can cut with a saw, but will be very heavey to hang.

Sheet metal: difficult to do yourself, I can't find anything on how to build yourself. If I go to a metal fabrication place with a design, what material and what thickness (gauge) should I ask for? (with cost in mind).

what other materials have people used? Aluminum siding? Foil backed insulation board?

Thank-you in advance for any comments.

Darrell
