Properly insulating a tiny house floor

Now that the frame is on and bolts are ready, I'll show how to properly insulate a tiny house floor with 3 1/2 of rigid foam board insulation. The 1 1/2" was installed first followed by the 2" on top, this will fill in the space of the 2 x 4 exactly. You can save money by finding damaged pieces at the big box stores, I got mine for 70% off because the corners were damaged. I knew I was going to be cutting mine anyway so I saved a Ton! Happy feet are warm feet.

Now that the insulation is fitted between the framing, I can start to think about sheeting the deck. I'm going to go with 3/4 plywood instead of the OSB, I think the plywood will be a little stronger with less flexing and weather a little better.. Hopefully I won't need to worry about the elements with the steel, exterior coatings and the interior but I base myself on Murphy's law.

Tiny house floor insulation even with the framing

With this tiny house, I'm going between the wheel wells as I'm not worried about the space since this is only a 14 foot long trailer to begin with, and this will be for summer/fall camping, not a live in year round type of structure.
