Insulating floor and ceiling
I have a great room with hardwood floors and a cathedral ceiling. It's always cold,especially the floor. There is no basement under that part of the house but a air space that t think I can get in. How can I insulate this floor? Can I insulate the ceiling also? Would I install "vats" to allow air to circulate and then fiberglass?

Hi dam
It sounds like just an open space underneath. In that case you would add insulation to the floor and cover the entire area to keep out the critters and eliminate as much air flow as possible. We can go into more detail as needed. Is there anything else down there, plumbing, heat ducts, or just support posts?
If you have an uninsulated cathedral ceiling, then you probably do not have vents in place. Typically you would need soffit vents and gable or ridge vents before you add insulation. BUT, rafters are often not deep enough to accommodate the desired amount of insulation.
Can you tell us how this room came to exist in PA without insulation. I'm not getting a good picture.

The floor is totally enclosed by stone foundation . There's just no basement under that part of the house. I would have to cut access in floor to get under it. There is wiring. The outlets are in the floor but I plan on changing that when I gut the room. The roof has vents but no vents in soffit. Not my doing. My house was a hunting cabin for a police department a long time ago and was upgraded to a house via add ons etc.

The foundation is fairly air tight.
The outlets and wiring are old. There's no ground on them or in the wiring. Or I'll rewire if I insulate the floor.
There's 6" between the ceiling and roof. They are true 2 x 6 's. There are only rafters like a cathedral ceiling. There are 4 square alum. vents near the peak.

Either way, the 4 existing roof vents need to be replaced with a ridge vent and soffit vents, so that every rafter bay is ventilated.
