Notes

  1. For the most up-to-date details, including construction variations, refer to the published assembly in the UL Product IQ™ database or GA Design Manual.
  2. Stud sizes and insulation thickness are minimum unless otherwise stated in the published assembly.
  3. Stud and fastener spacings are maximum unless otherwise stated in the published assembly.
  4. Panel orientation shall be as specified in the published assembly.
  5. Refer to applicable codes requirements to ensure compliance prior to construction.
  6. Where acoustical performance is provided in an estimated range, the values are based on laboratory test data of similarly constructed assemblies.
  7. Where design no. indicates “per”, the fire rating is based on laboratory test data of the referenced similarly constructed assemblies.
