I'm in the midst of having my existing chimney (30y/o Sellkirk Metalbestos) replaced, and looking over my options for SS Class A piping. Right now I could get everything I need in the Supervent (Menards) lineup, but was curious if I should look at other piping manufacturers? (Simpson Duravent?) Is there a reason to go with one brand or another? I know they all test to the same standards, but there are higher priced options out there. Is there a reason why I should look at them? Right now, my only reason to go with the Supervent stuff is ease of purchasing. (menards is 15mins away)
