I am working on finishing my basement. I am building a 4'X8' room to enlcose my furnace and water heater. The return ductwork (taken passively from exterior) for the furnace is currently snug against the concrete wall. Should this be re-worked so I can get framing and insulation and drywall behind the ductwork? This will be an expensive thing to do, but can be done. I want to build properly up to code. Basement walls are required to be insulated (R13) so my guess is that we will have to move the duct work in order to do so but I just want to make sure since if will cost extra. Any insight would be helpful. Just wondering if we can keep the furnace/water heater room unfinished.
Thanks,
