Acoustical Metal Deck

How acoustical steel deck works.

Acoustical metal deck.

Acoustical metal decking can provide sound attenuation in buildings where the deck is exposed to the interior. Available in a galvanized finish. The flutes of the deck are then filled with a sound absorbing material. They are capable of absorbing up to 80 of the sound that strikes the ceiling.

Verco s fluted acoustical n3 deck is made by perforating the webs of a standard verco deck profile. It comes with the option of two different gauges the metal deck panel is made in either 20 18 or 16 gauge. When sound in the room travels to the decking the insulation reduces the sound in a room by dampening the reverberation off of the decking. Available as an acoustic deck with nrc ratings as follows.

Type 2 0 s es acoustical from 90 to 1 15 type 2 0 ls es acoustical from 95 to 1 15 type 3 5 ls acoustical value of 95. The use of all acoustical deck is limited to non fire resistive assemblies. Type 3 5 ls acoustical can be used as a structural deck unit supporting lightweight insulating concrete lwic fm and icc approved unless otherwise noted. Cellular acoustical deck is also available in the same profiles.

Cellular acoustical metal decking is available in 1 deep and 3 deep fluted roof decks. Use them for interior ceilings soffits and exterior metal ceilings.
