I've got a 12x16 elevated sunroom with a very thin berber carpet directly on what appears to be planks of tongue and groove wood flooring. The bottom of these planks can be seen from below the sunroom outside, and are supported by 2x8 joists that run the 12', (roughly 16" O.C.)
We've placed a thick wool rug on top, but it's only 9x12ish, and the room is only nice in Spring and Fall. Space heater helps in the winter and window AC in the summer but both seem incredible wasteful given the absence of insulation. I suppose the walls have something, but with 10 windows (double pane, but older) on 3 walls it's just not great.
How best to insulate the floor? There is a slight step down from the house into the sunroom, so I could imagine maybe 1" of insulation that might sit directly on top of the wood, but it would have to be fully weight bearing such that we could place furniture and walk on it without any permanent compression.
Of course I can also do something on the underside as well, I am thinking cut sections of rigid foam for that, but I will have an opportunity to work on the inside soon and want a game plan.
