I'm getting ready to assemble some ductwork. Advice from an HVAC relative is to use silicone caulk to seal takeoff collars, duct joints, etc. Everything I read here references mastic/mesh and/or UL181 tape.
What would best practice be? If mastic, is the stuff available at home centers good, or do I need to go to an hvac supply house?
thanks!
