Structural and Non-Structural Wood Testing

OSB Board
NTA offers testing programs for a variety of structural and non-structural wood building products for markets both domestically and internationally.

NTA currently performs testing to determine the code compliance of:

  • Oriented strand board (OSB)
  • Plywood
  • Wood panel siding
  • Formaldehyde emissions from wood-based panels
  • Particleboard
  • Medium-density fiberboard (MDF)
  • Proprietary wood structural panels
  • Proprietary sheathing
  • Structural wood-based and engineered wood products
  • Laminated wood structural panel
  • Oriented structural straw board
