How to insulate a 3 season porch

Our house we just bought has a room that was built on an existing deck. It has insulation in ceiling and walls. The floor is just the old deck with stained plywood on top. No insulation. It is basically a deck converted to sun porch converted to 3 season room. No HVAC to this room. The outside clearance to try and crawl under is only 12". There is no way to insulate from outside under the exposed deck. How do I go about insulating the floor from the inside?
