I bought this home almost two years ago. And this year I suddenly had an influx of heat in my 2nd story bathroom. Lots of warm air was being dumped into the room from behind one of my bathroom cabinets.
-------------------------------
The wall behind the cabinet has plumbing of course, but apparently at some point the loose insulation on this wall fell. I put a camera and light inside, and this revealed that the enclosed attic above the dining room has no insulation.
-------------------------------
I had done a thermal survey of the house when it was cold, but not yet when it was hot.
The dining room was one area which was hot in the summer, but I had chocked that up to the three western facing windows here. And last year I had put in 60% sun shades on the outside.
Now that I discovered the issue upstairs, I can see that the dining ceiling isn't doing any good.
-------------------------------
The dining room is an outcropping on the house. It effectively has its own roof. The construction is typical of the area, with composite shingles over plywood. The outside walls in the attic also appear to have no insulation, but the external construction is 4" thick limestone masonry.
-------------------------------
The upstairs bathroom was redone at some point in the past. And they moved at least one of the sinks.
In doing that remodel, they tore a sizable hole in the drywall, and covered it up with the cabinet (which had a slightly smaller hole).
The hole is big enough to put a GoPro on a selfie stick to get these shots.
-------------------------------
The insulation behind this wall is loose, and has nothing to prevent it from falling. So it was inevitable that this would have occured.
-------------------------------
What I need help with is advise on the best way to insulate this near inaccessible attic.
Last year I has blown in insulation added to the entire accessible attic spaces of the home. It seems possible that they could remove the loose bathroom cabinet, and gain enough access on the 2nd story to blow in insulation into this space. But coverage without better access seems like it might be spotty, or clog the vents.
Any other ideas?
