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