Waveform ® Spline G
PRODUCT OVERVIEW The Waveform ® Spline G Panel represents the evolution in architectural acoustics toward quantifiable, organic shapes. Developed using RPG’s powerful shape optimization software, the panels have an attractive multi-curved appearance and are designed to bring early diffuse reflections to the audience, increase intelligibility and enhance musical clarity and intimacy. One of the most powerful one-dimensional sound diffusers available today, the asymmetric Waveform ® Spline G Panel is constructed of non-combustible glass fiber reinforced gypsum (GFRG). They can be arrayed to reduce periodicity effects and be installed on walls or ceilings. SIZING • Standard Panel: 4' W x 8' L x 12-3/4" D • Material Thickness: 1/8" nominal (Additional thicknesses may be available) • Each panel weighs approx. 3.00 lbs/ft 2
Blue = Diffusion Coefficient Green = Scattering Coefficient Red = Absorption Coefficient - NRC = 0.15, SAA = 0.12

The Waveform ® Spline G Panel comes in a natural/raw GFRG finish and required to be painted on-site or factory color-matched to any paint color specification. INSTALLATION Overhead mounting of the Waveform ® Spline G Panel is achieved by suspending units from integrated hairpin loops using RPG-supplied engineered cables and hardware. Each panel is designed to hang freely as a separate “cloud” or screwed together along the long edge to create a linear canopy. Units can also be mounted directly to walls using RPG-provided integrated cleats.
