Insulating fishhouse floor?

[huntingfisher]

Got a 7x10 house on wheels.  Wondering what the best material and way to attach it to the floor.  Though about spray in foam but didn't know if it would be a bugger with the wiring and if ever had to get under to do any work "hope not".  Any ideas or thought would be great.

if you do spray on, keep it off the ice. warm ice equals water. that type of insulation will retain miosture. maybe there is some sort of sealantfor it?

alot of houses are built like this

frame, sheating, insulation, then flooring or sheating.
some are built with the insulation directly on top of the frame then the sheating.
if your floor was constructed without, you might want to think about laying sheet insulation on top of the floor and then re-sheeting the floor on top of that and re-opening your holes and raising your hole covers if you follow me.

i would have to disagree with jiggle on the spray in foam.  I have it on my house and have had zero problems with water under the house and wet foam, ect...
The spary foam seals on the outside and will not soak up water.  and also, the foam holds in heat, it will not heat up the under side of the house anymore then a regular non spray foam floor does.  I never once last year moved the house and had melted ice and snow underneath.  If you can swing it, for sure go with the spray.  And as far as wires, easy... if you need to add, just notch a V in and put your wires up in there and then get a can of spray foam and spray/fill in the V groove.  simple.
