Gypsum Wallboard/Drywall Testing

Progressive manufacturers of gypsum wallboard products are looking for the next innovation to set the stage for their long-term success, which may take the form of value-added performance to existing gypsum wallboard products or diversification into new applications of their existing knowledge and technology. Forward-thinking manufacturers set the pace for new market-ready solutions when supported by a collaborative and innovative third-party partner such as ICC NTA.

ICC NTA laboratories are accredited to the ISO 17025 standard, which ensures that you and your customers can rely on the validity of our results. Our team also understands how important test results are for your business goals and objectives — all our team members work together with you to efficiently conduct tests and prepare the test reports you need. We conduct tests of gypsum wallboard for various characteristics, including but not limited to:

  • Ceiling board
  • Dimensions and tolerances
  • Exterior gypsum soffit
  • Fire resistance
  • Flexural strength
  • Gypsum sheathing
  • Humidified deflection
  • Nail pull resistance
  • Product sampling for testing
  • Shear strength
  • Water resistance
