I think it is SC50 Sound Control Underlayment

The builders ignored our original assembly specs and substituted this underlayment and omitted the resilient strapping; a headache to say the least. Anyway, I would appreciate any feedback on this assembly as it now stands.

Our floor assembly (top to bottom):

3/4" oak plank flooring nailed down

2 layers 1/2" OSB glued together and to the slab with Bostik's Best Poly adhesive

1 1/4" gypsum slab

SC50 underlayment

3/4" plywood subfloor

11 7/8" TJI floor joists - cavity filled with wet-spray cellulose insulation

3/4" wood strapping

2 layers 5/8" sheetrock

Wood transfer sound very well so try and use as little ass possible.
