What you’re looking at so avidly is part of the ceiling of the Cabin at the End of the Road at Roundrock. It’s actually directly above the new mouse-proof cabinet, but that’s not essential to know.
When the cabin was built, the walls and ceiling were wrapped with the foil sheathing as an insulator. It’s not very thick, but I’m told it makes a difference. Anyway, the bolts of this sheathing were shorter in dimension than the height of the wall, so there are seams where the wrapping had to overlap. Some time ago I had taped these seams (with duct tape originally but later I finished the job with specially designed foil tape, which works much better). I had even brought a ladder to the cabin so I could tape the seams in the ceiling.
I had done this for two reasons, reasons that made sense in my head even if they don’t in actual performance. One reason was to complete the seal so that the insulating sheathing would work better. The second reason was to prevent incursion by insects, which could easily get behind the exterior siding and then find their way to the seams and come on in the cabin. The ultimate goal is to properly insulate the walls, lay a vapor barrier, then cover them with wall board. Once I’ve done that, I won’t have access to the interior of the walls, and if insects did manage to get in and cause mischief, I would likely not know about it — or be able to do anything about it — until it was a big problem. Thus the proactive attempt.
But I missed a spot. I guess the builders had run out of continuous sheets of the sheathing and had to complete this little corner of the ceiling with leftover pieces. (Notice how my taping job did not have to continue up the ceiling.) I had overlooked this patch job because I wasn’t expecting to find any seam other than the regular ones.
Knowing that I was going to muscle the the mouse-proof cabinet into the corner — and that I would not want to be moving it again if I could help it — I decided it was time to tape these last seams. Fortunately they were low enuf that I could reach them standing on a chair, so I didn’t have to schlepp a ladder to the cabin to do it.
And in short order, the job was done, as you can see.
Regarding the insect incursions, there is a bit of taped seam at eye level near the door that had peeled away and fell a bit. Stuck to the tape I found several insects, desiccated and liberated from their earthly toil. Had they found their way in behind the siding and found the seam, only to be stopped by the tape? Or had the tape fallen away and the unfortunate insects merely stumbled onto it and found themselves stuck? Regardless, I’m glad I’ve done all of the taping, even if I won’t finish the insulating and boarding for a while.
