Dimond NPM 900 - Metal Tray
Dimond NPM 900 - Metal Tray
Dimond has worked with Nuralite to develop NPM 900, a metal tray that is perfect for under Enertherm PIR insulation boards. NPM 900 has been designed with strong ribs that resist buckling under concentrated loads reducing the chance of damage on roofs or deflection.

The system is installed with a wide surface for the boards to be laid onto and for the screws to fasten into. Conservative spans are 3m internal and 2m external. The minimum thickness is 0.55 though other options are available to accommodate wider spans.

By significantly increasing the spans over plywood structures, significant savings are made in building time and material costs.
Product Benefits:
  • Lightweight building structure.
  • Quicker build times.
  • Cheaper than using plywood as a substrate.
