I bought a home that has an addition which is built on concrete
pillars, much like a deck would be. The builder put fiberglass
insulation between the floor joists, and it just fell out onto the
ground (brilliant, eh?).
The room is cold in winter and hot in summer, and I need advice on how
to better insulate the floor.
I was planning on putting new fiberglass insulation between the joists,
then covering it with foam sheet insulation. I don't know if this will
make it any better or worse, but I am at a loss as to what to do here.
Any comments, advice appreciated.
