How do I know if my deck is Acoustical, Cellular, or Cellular & Acoustical?

ACOUSTICAL DECK

  • Standard roof deck profile with perforations in the webs (vertical portions of the roof deck flutes).
  • The fiberglass acoustical deck insulation that will absorb the sound is field installed into the roof deck flutes from the top side of the deck.
  • No flat plate attached to the bottom of the deck.
  • Suited for use in gymnasiums, auditoriums, and theaters where noise reduction is required.
  • The impact to the strength of the panel is negligible, so standard load tables are used when designing acoustical deck.
  • Recommended finish is galvanized or galvanized and painted since rust stains may occur at perforations in non-galvanized deck.

CELLULAR DECK

  • Standard deck profile with a solid flat plate attached to bottom via spot welding or riveting.
  • No perforations on deck top or bottom flat plate.
  • From underneath, the bottom flat plate will give the deck a flat, aesthetically pleasing appearance.
  • Specified often for flat ceilings, canopies, long span conditions, and electrified raceways where wires run through the cells.
  • Can be ordered with different gauges for top deck and bottom plate depending on loading requirements.
  • Produced with galvanized deck and either a galvanized or galvanized and painted bottom plate.

CELLULAR & ACOUSTICAL DECK

  • Identical to cellular steel deck, except that the bottom flat plate is perforated with staggered holes below the open cells and solid at the bottom flanges.
  • From underneath, the bottom flat plate will give the deck a flat, aesthetically pleasing appearance, but this time with holes.
  • Fiberglass cellular and acoustical deck insulation is either factory installed or field inserted into the cell between the deck panel and the perforated roof deck plate to absorb sound.
  • Suited for use in gymnasiums, auditoriums, and theaters where noise   reduction is required.
  • Can be ordered with different gauges for top deck and bottom perforated plate depending on loading requirements.
  • Produced with galvanized deck and either a galvanized or galvanized and painted bottom plate.
