I have a tri-level house and want to insulate over the uninsulated
slab. What I planned is outlined below. Please critique and give
1. glue over current vinyl tiles 2 sheets 4 mill plastic.
2. make grid with 2x4's with 16" centers.
3. fill with fiberglass batting.
4. cover with 5/8" plywood
5. install composite flooring such as Pergo

FWIW, I'd do it a bit differently:
1. 4 mil plastic with adhesive below and above.
2. Put down 2" compressible styrofoam (same as used under concrete).
3. Apply 3/4" UL over foam with adhesive.
4. Your choice of flooring.
1. Less loss of height
2. Much higher R value.
I included the 4 mil plastic, but I'm not sure it's needed. The vinyl
tile and it's adhesive may effectively seal the existing floor. I
would guess if you put some plastic over the existing floor and don't
see any condensation inside of it, you may not need it.
