The durability and versatility of prefinished Gridstone ceiling panels

Mar 7, 2024

Gridstone gypsum ceiling panels are USDA approved and install easily in standard exposed grid systems


From commercial kitchens and food-processing facilities to hospitals and schools, suspended ceilings are a popular design choice given their versatility and ease of installation. These ceilings are typically constructed using a 15/16" exposed metal grid system suspended with wires from the building structure. The ceiling panels create a finished appearance while still providing access to the plumbing, electrical, fire suppression and other equipment located above.

National Gypsum Company, through its affiliate Gold Bond Building Products, LLC, provides three variations of Gold Bond® Gridstone® gypsum ceiling panels, each offering unique benefits based on project location.

  • Gridstone® Gypsum Ceiling Panels feature a sturdy vinyl laminate with a smooth, durable, washable surface. They are USDA approved and suitable for use in kitchens and food-service areas.
  • Gridstone® CleanRoom Gypsum Ceiling Panels feature a vinyl laminate on the top and the bottom and sealed edges to help maintain low levels of airborne particulates in clean rooms, server rooms and other areas requiring high levels of cleanliness.
  • Gridstone® Hi-Strength Ceiling Panels are 40% lighter than standard gypsum ceiling panels for easier installation. These panels, which also feature a vinyl laminate, are USDA approved and suitable for use in kitchens and food-processing areas.

Aesthetics meets functionality

Backed by a 15-year limited warranty, Gridstone ceiling panels feature a noncombustible gypsum core and a 2-mil, vinyl laminate, which combines high light reflectance with easy cleanability.

“Gridstone panels are ideal for interior commercial ceilings, as well as unexposed exterior ceiling applications, such as soffits and parking garages. And because the panels are factory finished with a sturdy vinyl laminate, they do not require painting.”
