Some of the things I wanted in a manufactured home are ILLEGAL. I thought it was extremely strange that I would have to get a ducted HVAC system. Under floor heating is for some reason literally illegal (unless you retrofit it) and I am still scratching my head as to why.

Mobile homes generally have little no insulation of any kind underneath, and their subfloors are exposed to exterior air, so the heat would be quickly lost to the outside environment. You could in theory make a highly insulated subfloor on a mobile home (i.e. 2" of polyiso foam board) on which you could install electric or hydronic heating, but you would then lose a significant amount of already limited ceiling height.

Almost every one I've worked on has a 3/4" sub floor (probably cheap press board), loose fill insulation in between the 2x6 joists, then plastic (5 mil maybe?) attached to the under side of the floor joists. That plastic tends to be very ripped up so much of the floor has exposed or no insulation under it.
- danans 4y agoSo little to no insulation. What you describe is "little" insulation. In climates like CA it tends toward "no insulation".
- rascul 4y agoI didn't mean to contradict you, just to expand on it a bit. The insulation is generally crap, in the places it exists. Edit: Sorry if my comment came out the wrong way.

- StillBored 4y agoHaving lived in a mobile home for a couple years, I can say that a large part of my hatred for OSB/particle board comes from that house. It seems pretty much every mobile home i've ever been in suffers from sponge floor, which is the OSB degrading to the point that the carpet is providing more structural support. Eventually the flooring gives way, and its becomes possible to stick ones floot through the floor. When I was living in that home (as a Highschool student) one of the things I spend many hours doing is ripping up the floors and replacing them with actual plywood, which seems to be significantly more robust when used as a flooring material.
- rascul 4y agoI've actually never seen OSB for a mobile home sub floor. A couple times it's been plywood but other than that it's always been press board.
