RPG Acoustic Glass-Reinforced-Gypsum Diffusers:
Optimal acoustic performance is what RPG has delivered with molded GRG diffusers. Available as clouds and lay-in panels, RPG's "G" line of ceiling and wall products covers 1D and 2D diffusion, as well as reflectors. The stiff material eliminates the diaphramatic absorption seen with plastics, without the need for added insulation or thicker materials. Products include the Harmonix G, Waveform Bicubic G, Waveform Biradial G, Waveform Monoradial G, and many others. With a variety of appearances there's never been a better way to balance the performance of a ceiling with modern aesthetics.
