From the postings I've seen already it looks like this will be an easy one for some of you out there. I'm finishing my basement in my one year old home and was wondering if I needed to use insulated flex duct. The ductwork that exists in the basement already, feeding the first floor, is insulated. I'm assuming that's only because the basement was unfinished. Is this correct? Can I get away with using uninsulated flex to feed the basement from a dedicated unit in the basement.
Hi Eric, I'll try to answer, flex ducts biggest problem is installer error. If you use flexduct make sure there are no kinks twists, smashed areas or it is useless. Dont know were you are but we use uninsulated metal duct here[wi.] Some use flex if the runs are nice open, straight and clear. Flex is fine because it is insulted, but must be installed properly, good luck Victor
