Rockfon Koral ceiling panels
offer great sound absorption, high light reflectance and lightly textured white surface
Blending aesthetics, performance and ease of installation, Rockfon® Koral™ stone wool acoustic ceiling panels feature a lightly textured, painted white surface, good sound absorption, high light reflectance, fire protection and humidity resistance. Rockfon Koral panels are well suited to create modular ceiling designs such as open-plan offices, retail centers, commercial kitchens and baths, long corridors, large classrooms, and convention centers.
“The attractive, lightly textured, painted white surface of Rockfon Koral panels has high light reflectance with an LR of 0.86. Maximizing the use of natural light may allow the number of light fixtures to be reduced; lowering electronic light loads and reducing cooling costs,” said Cory Nevins, ROCKFON’s director of marketing for North America. “These panels also deliver great speech privacy performance and very high sound absorption with an NRC of 0.85.”
Rockfon Koral’s high Noise Reduction Coefficient (NRC) mitigates what is known as the “cocktail effect,” explained ROCKFON’s district manager for Ontario and western Canada, Scott Debenham. “When a large group of people gathers in an open space, they escalate the volume of their voices, competing to hear one another. This makes it increasingly difficult to hear the individual conversations taking place. Our stone wool ceiling panels’ high sound absorption makes it easier to hear one another without raising your voice, as well as enhances speech intelligibility to hear a speaker addressing the large group.”
Contributing to building’s environmental goals, Rockfon Koral ceiling panels contain up to 34 percent recycled content. ROCKFON’s extensive portfolio of stone wool acoustic ceiling solutions has earned UL® Environment’s GREENGUARD Gold Certification for low-emitting products.
Available with either a square tegular, square tegular narrow or square lay-in edge, Rockfon Koral may be specified in 2-by-2-foot or 2-by-4-foot sizes. As with all of ROCKFON’s stone wool ceiling panels, these panels also are 50 to 75 percent lighter than other ceiling panels for easier installation. Providing low maintenance and long-term durability, ROCKFON products supplied in North America are supported with a 10-year product and 30-year limited system warranty.
