Fiberock Panels are a unique, gypsum fibre product that includes a water-resistant core for supreme durability and superior performance. Easy to cut and install, these panels are highly desirable and durable in wet and dry environments alike.

Fiberock linings can be used in ceiling applications as well as interior walls, including exterior areas protected from direct exposure to rain such as alfresco dining, verandas, carports, soffits or eaves that are horizontal or incline down away from the building.

Key Features
  • Three product thicknesses for uniformity with other USG Boral Plasterboard systems
  • Exceptional impact resistance; at least as strong as 9mm Fibre cement and twice the strength of same thickness regular core plasterboard
  • Screws, nails, glues, staples and joints easily to provide monolithic finishes
  • Two way fire rated systems up to 60 minutes (single layer) and 120 minutes (2 layers)
  • High mass gives superior noise control, including inter-tenancy rated systems
  • Excellent substrate for paint and tiles, and a number of abrasion resistant coatings
  • Many fixtures can be attached without the need to screw into stud or nogs
  • No paper face to scratch, tear or delaminate
