Bathroom Fan Vent Pipe

2 I'm planning on installing a Bathroom exhaust fan (Just a note, the port is 4") and am curious as to what kind of duct should be used. I've heard that the duct should be insulated to prevent water backflow from condensation during the colder months as my attic is not environmentally controlled. While both insulated and uninsulated exhaust pipes will get the air out of your bathroom, the insulated duct does this better.

The better insulated your exhaust pipe is, the more efficiently it can expel air from your bathroom. Humidity, moisture, foul odors, and dust particles get expelled by a properly insulated bathroom fan exhaust pipe. If you are venting a bathroom with a tub/shower the best way is to vent straight up through the roof using 4 inch or bigger aluminum pipe (not flexible) wrapped in pipe insulation up through a roof vent that has a back draft damper.

Regarding the tee, I want the fan to exhaust from 2 rooms (one's the main area of the bath with shower, the other has the toilet behind a separate door). So, there's one timer to activate the fan, but it has 2 openings, one in each area of the bathroom.

Maybe "splitter" is the right word to use rather than tee. The vent kit should consist of the vent cover itself and a three or 4-inch pipe to connect to your flexible duct. PVC piping is an excellent material to use for venting your bathroom fan as long as the correct type of pipe is used.
