Verco PLN3-32 AC

PLN3-32 AC Acoustical Decking - 3" Deep

Acoustical metal decking can provide sound attenuation in buildings where the deck is exposed to the interior. The use of all acoustical deck is limited to non-fire-resistive assemblies. Verco’s fluted acoustical Punchlok N deck is made by perforating the webs of a standard Verco deck profile. PLN3-32-AC metal deck types has perforations in 10 of the 12 webs. The webs adjacent to the sidelaps of PLN3-32-AC are not perforated. The roofing contractor installs the acoustical insulation batts(supplied with the deck) prior to the placement of roofing insulation.

PLN3-32 and HSN3 AC panels are identical in both geometry and material properties. The prefix "PL" designates a PunchLok II version of the N profile. When the job is specified as Punchlok II, then a Punchlok II tool must be used for the sidelap attachment. This method of attachment allows for higher shear values and must be done correctly or the building design could fail. 

PLN3-32 AC is NOT in stock. Custom ordered jobs only. Minimum quantities apply.
