I've got an upstairs bathroom and 3 closets that need access doors built that will allow a person to crawl through to get into the attic. Since this is Texas (hot) and this is from conditioned space into unconditioned space, the doors also need to be insulated (probably using foamboard).

I'd like the doors to look decent. I'd kind of like them to "blend in" with the walls as much as possible. Having them insulated, I think, adds a bit of complexity.

2 of the doors will definitely open in. 2 of the doors may be able to open out which is nice/better in some ways but probably adds more complexity to have the face flush with the inside wall.

The openings are 36-44" tall and 18-22" wide.

I've been thinking:

1. frame the holes (already done, one or two may require a header, then finish with corner bead for a square, finished, flush look.
2. build a small hollow door with foam board insulation as "fill." Frame out of 2x2 (or maybe even 1x2) with 1/4" ply for the face (maybe use 3/8" lightrock for the face in the bathroom). Then at least 2-3 layers of 3/4" foam insulation in/behind the frame. I'd originally thought of having a plywood face on the back of the door too, but I'm not sure if that's necessary.
3. some sort of door stop with weatherstriping along the edge. Or maybe a tear drop shaped weather stripping to seal the gap around the door.
4. Possibly using one of those magnetic door catches (bump the door and it pops open) for the bathroom.
   
   Maybe the same for the others or something else (small hook and latch or something simple

Any other thoughts? I've seen some folks that build a frame and attach that to some drywall so the face is drywall. I could go that route in the bathroom where visual aesthetics is more important. I could probably still build the door similarly. I've been using 5/8 fire rated drywall in the house to help with sound, but for a door like that it seems like a "lightrock" 3/8" or 1/2" would be better, still with a frame and foam board. I think you can sometimes get half sheets, or small sheets at some HW stores.

In the closets, the doors will likely be all or mostly hidden behind clothes or boxes so smooth plywood should be "good enough"

Any thoughts, why that won't work, inadequacies, improvements?
