WE are remodeling one of our mobile homes, it is a 1980 12x65. We removed the dividers and kitchen cabinets so we could replace the floor in the kitchen and living room. What we have now is a 12x27' open room with the presswood floor completely removed. The underbelly only had a 5 places that had been cut by the PO when plumbing repairs were done and we repaired them as well as ran new plumbing lines while the floor was open. For the most part over half of the insulation is in tact. We have several rolls of R19 paper backed insulation in our storage unit. Would that be ok to use? If so, which side would you face the paper to? When moving around some of the old insulation, it appears that there was a paper backing facing the underbelly material that is now stuck to the underbelly material. Would it be better to buy unfaced insulation and just fill in the missing and low areas or can we use what we have on hand? The underbelly is the material is not the board like material, it is the tarp like material that drapes under the entire home.
As the unit had a roach problem after the last tenants lived in it for a year, we are also planning on spraying before putting down the new plywood. Any advice on that would be appreciated too.
