If you replace the insulation with same type stuff I don't think there would be any problem with that. Almost any type of tape or plastic would seal it back up.

If the supply duct to the old wall register runs in/under the floor it shouldn't be hard turning it into a floor register. You might get by as simply as buying and mounting a floor register; that's...

When you say you're going to run 8" round duct, I hope it's 8" round "metal" duct. As it is going to be run 20 feet and as you say the airflow in that area is just acceptable (I read that as just...

It seems I've read that in duct selection that the cooling needs usually require larger ducts than heating needs. Since your home was originally designed only for a heating system, your duct system...

The part that bothers me is that you say when the bedroom door is open that you still don't get that much airflow. Your open door is acting as a return (and a big one at that).
