Bathroom exhaust vent need to be insulated?

I live in Los Angeles near the coast. It never gets all that cold here. In winter temps get into the 40's. I'm installing a Nutone heater/vent/light. Must the exhaust duct be insulated or can I just use a standard dryer vent with the foil? I am having to travel about 10 or 12 feet to the louver that vents outside.

Typically insulated ductwork is done to eliminate any condensation problems right from the start.
There is nothing that says you must use it. Try regular ducting. Run it pitched towards the outside.
Keep an eye out for condensation dripping from the fan.
