This is a follow up on my first thread on rot (https://www.fiberglassrv.com/forums/...rot-91655.html
). I thinkI have a plan in place to replace the possibly rotten floor. After that, we need to close the wall back up. In the attached photo of the completed demo, you can see the extruded polystyrene that is glued in relatively large pieces to all the walls. This was covered with glued on lauan. There are large gaps in the corners that had been filled with fiberglass batt-style insulation. The ceiling has polystyrene board, and some thinner white foam. The ceiling was originally covered with a carpet like headliner. I want to more or less emulate the original wall covering method with lauan, but i want tighter corners. Originally there was a angled piece of wood in there, stapled to the lauan on the walls, then had a small piece of lauan glued to it. See second photo of close up of corner (not sure how to rotate - carpet goes up).
My first thought is to get some more foam board, cut to fit closer to the corners...I will still need a corner piece of some sort?
Second part - dust. In taking the walls off, it is shocking how much dust was collecting in behind the wall panels. Well, maybe not that shocking considering the number of vents/holes (fridge, HW tank, furnace
, lights). The fridge
especially is thick with dust. Is there a way to prevent this? I guess it wasn't really coming into the living space, so maybe not that big a deal?
