LEVELROCK® CSD™ EARLY EXPOSURE™ Floor Underlayment
Enables underlayment to be poured up to 60 days before permanent windows and doors are installed.

Designed for interior use in buildings with light-gauge steel framing and a corrugated steel deck, it may be applied at a much lower thickness than poured-in-place concrete, reducing dead load and allowing a greater number of floors for increased rentable/sellable square footage.
