I have recently begun renovating a 1972? MH. It is 12x72 flat roofed. I have a few questions which hopefully you all can help with: 1) What type, thickness, r-value insulation is typically used in the ceilings? It is unfaced fiberglass, but i don't know what i need to replace it with) 2) I have read about insulation beneath the MH and i understand that many people use tarps to hold the insulation up. Would using housewrap be a better option? (i have some left over from when i resided my home) 3) The home is really a summer gettaway/ hunting site. So most of the time the windows are closed, electric shut down, no constant temp inside. I would like to replace the carpets. Would laminate flooring work under these conditions or would they warp/bow? 4) Lastly...for now..is the plumbing in MH standard sizes ...1/2 in 3/4, etc that can be found in any home inprovement store? I appreciate any help. I know that many of these questions belong in other forums, but it was easier that posting 5 diff posts. If needed, i will do that later. Also, because the MH is 45 mins from closest supply store, i am trying to self educate to eliminate too many trips. Cheers! birch

I’m trying to complete a few projects on one side of my house in the coming weeks. I’m hiring a contractor to convert the rough openings for a door and window into a rough opening for a French door and to install the French door. I’m residing the wall and installing a few new windows in the process. The week before I install the siding, I’m having new hardwood floors put down. So that’s the background. Behind my current siding I have ½” rigid foam board with a foil face. My walls are 2x4 and have fiberglass mat insulation. I’d like to improve my energy efficiency and certainly don’t want to decrease it. That means that I’ll either have to improve the insulation in my walls or keep/replace my current rigid foam board. I guess my first question is, is blowing in cellulose and discarding the foam board a viable option? I’m not sure if blowing around fiberglass is feasible or if it will even make much of a difference. Due to timing constraints, my plan is to have the doors installed ahead of tearing off the old siding. If I go the foam board route, am I pretty much stuck using my existing foam? My understanding is that doors and windows have to be installed on top of foam.
