Hello,
I am in the midst of a complete bathroom gut on the top floor and have everything down to the studs. I'm actually at the point where I'm about to close up the walls.....
So the problem is the insulation (and the overall workmanship in this house) is terrible. Most of the walls have a super thin 2" foil backed insulation that literally does nothing. Anyways, I popped my head up into the attic area (between the bedroom ceilings and the roof) and there is minimal insuation that doesn't even cover the 2x4 rafters. Some of the rafters are 2x6 but I'd say 2/3 of them are 2x4 (workmanship, cough, cough).
There are no soffit vents. I only have a vent on the side of the roof that's about 12" square on both sides of the house.
Here's a quick video I did scanning the entire area.
This is what I'm thinking as a plan. Please feel free to correct/suggest/criticize/whatever you see fit.
1. Since I have the ceiling exposed, I can climb up above the ceiling of the top floor and get a whole bunch of unfaced R-30 and lay it perpendicular on top of the existing rafters. Maybe something like this that I can get at the box store. I could use a 3/4 24" piece of plywood as a temporary mobile floor. I'm almost 300lbs so it might get a little sketchy up there.

2. Install faced R-13 in the ceiling of the bathroom on the all the rafters then lay R-30 unfaced on top of that perpendicular as well.

3. I'll have to cut an access hole and frame up a hatch so that I access it from the hallway.
4. I also have knee walls that had insulation installed incorrectly by a contractor friend. He installed batt insulation with the face exposed. I believe the face should be closer to the conditioned space not the crawl space. I can remove those and install some 2" foam boards and seal with fire retardant foam. Maybe I should double up the boards? If so they would protrude from the 2x4 slightly......

I have 5 interior mini-split units with 2 exterior units. 1 for each bedroom and 1 larger unit for the living room. The bathroom will have a surface mounted electric heater.
Thanks in advance and here's a link to my bathroom remodel.
