One of my homes is vacant and am rehabbing. In the process or taking down a lot of rotten skirting I found most of the insulation hanging down - the underbelly fabric is effectively gone - which I suppose is common for an early 80’s singlewide. This is in TX and fortunately doesn’t really get below freezing except once or twice a year at this location.
Speaking with several mobile home repairmen the consensus is to replace the pink insulation and staple chicken wire to hold it up, or alternatively nail up a thin plywood square to the joists to allow continued breathing.
Anyone else have an approach that works better for them when doing an entire underbelly or major patchwork? Doing nothing is not an option I’m considering yet, but maybe after this I will.
