Deep-Dek® 4.5 Cellular Acoustical (Roof)

Deep-Dek® 4.5 Cellular Acoustical is a double cell (hat) unit with a perforated Klean Line-R™ liner panel that provides a support surface for various component roof systems. It can be used as a secondary structural member to provide for lateral force distribution to the structure’s vertical force resisting systems. Fiberglass insulation batts are installed in the deck cells at the factory under controlled conditions. Deep-Dek® 4.5 Cellular Acoustical product produces a smooth underside surface with subtle shadow lines for a clean finished look and a noise reduction coefficient (NRC) value of 1.00.

All Deep-Dek® features offer exceptional performance:

  • Wind resistance, snow loads, seismic, etc.
  • Open, unobstructed building environments
  • Exceptional aesthetics
  • Quiet
  • Dek-Knek® Sidelap Attachment System

Deep-Dek® 4.5 Cellular Acoustical is available in a twenty-four inch (24”) cover width. It is available in nine (9) steel gage thicknesses (see load tables), with various deck/liner panel thicknesses, a variety of galvanized coating weights and an array of paint systems all suited to specific project performance specifications.
