Scope of Use

High-performance gypsum-fiber roof board for use in low slope commercial roofing systems

  • Exceptional bond and low absorption in adhered systems
  • Moisture and mould-resistant
  • Excellent wind-uplift performance
Limitations on Use
  • USG Boral Securock Gypsum-Fiber Roof Board is engineered to perform within a properly designed roof system. The use of USG Boral Securock Gypsum-Fiber Roof Board as a roofing component is the responsibility of the design professional.
  • Keep USG Boral Securock Gypsum-Fiber Roof Board panels dry before, during and after installation. USG Boral Securock Gypsum-Fiber Roof Board should not be installed during rain, heavy fog or any other conditions that deposit moisture on the surface of the board. Apply only as much USG Boral Securock Gypsum-Fiber Roof Board that can be covered by final roof membrane system in the same day. Avoid exposure to moisture from leaks or condensation.
  • For reroof or re-cover applications, existing roofing system must be dry throughout prior to application of USG Boral Securock Gypsum-Fiber Roof Board.
  • USG Boral recommends maximum asphalt application temperature for Type III asphalt of 235°C when using USG Boral Securock Gypsum-Fiber Roof Board. Application temperatures above these recommended temperatures may adversely affect roof system performance.
