Types NW32 and N are 3-inch roof deck profiles that make large open spaces possible in structures such as gymnasiums, limiting the number of structural supporting members required. Choose from 32-inch coverage, standard 24-inch coverage, cellular and inverted configurations. NW32 is available with nested or interlocking side laps. N deck is available with nested side laps only. All NW32 and N deck variations are available with acoustical options.
Available in lengths from 6’-0” to 40’-0”. Check with your local New Millennium facility for lengths outside these parameters. Conforms to ASTM A1008/A1008M for uncoated and painted deck, and A653/A653M for galvanized deck. Approved by UL, ULC and listed in the UL and ULC Fire Resistance Directories.
Yield strength up to 80ksi. Refer to published tables for the minimum yield strength used for each deck type. Contact New Millennium for availability of higher yield strengths when required or use our deck specification tool to view load tables with commonly available non-standard yield strengths and/or gages.
More than just a wider version of N deck, NW32 introduces several benefits. At 32 inches wide, NW32 is 33 percent wider than Standard N deck. Coverage is achieved with fewer panels, which means less labor, lower costs and faster installation.
N-Dek Cellular is a 3-inch-deep, cellular structural roof deck unit that provides a support surface for various types of roofing materials. The liner panel with the Dek-Knek® Side Lap Attachment System provides a finished underside ceiling with self-aligning side laps and concealed fasteners. N-Dek Cellular Acoustical features a perforated liner panel that provides an NRC value of 0.95 with rigid insulation. Fiberglass insulation batts are installed in the deck cells at the factory under controlled conditions.
Inverted N-Dek is the 3-inch N-Dek profile placed in the inverted position for a unique ceiling aesthetic that provides a smooth ceiling appearance with heavy shadow lines. Inverted N-Dek Acoustical is a 3-inch deep, wide-rib, inverted, acoustical structural roof deck unit that provides a support surface for various types of roofing materials with an NRC of 0.80 when used with rigid roofing insulation.
