Modffractal ™
PRODUCT OVERVIEW Modffractal TM is part of the evolution in architectural acoustics toward aperiodic sequencing of asymmetrical shapes. It provides full-spectrum sound diffusion in a single integrated diffusor by combining the self-similarity properties of fractals with the uniform scattering property of a phase-optimized sound diffuser. This unique and patented design expands the bandwidth and offers the broadest spectrum of sound diffusion available while also allowing optimized array sequencing for further improved performance. The inset wells can also be slotted for improved lower midrange absorption below the low-frequency diffusion cutoff. Units are available in a high recycled content, ULEF, Class A fire-rated and FSC ® -certified MDF core, and FSC ® - solid wood wells. SIZING • Standard Unit: 23-5/8" W x 47-1/4" L x 7-7/8" D • Maximum Unit: 23-5/8" W x 8' L x 7-7/8" D
Blue = Diffusion Coefficient (mid) Light Blue = Diffusion Coefficient (high) Green = Scattering Coefficient (mid) Light Green = Scattering Coefficient (high) Red = Absorption Coefficient - NRC = 0.30, SAA = 0.26
(Custom panel lengths are available) • Each panel weighs approx. 7.50 lbs/ft 2
CORE FIRE RATING Class A (per ASTM E-84) FINISH

Modffractal TM is available in various finishes, including solid woods (Ash, Birch, Cherry, Mahogany, Maple, Poplar, Red Oak, Walnut, White Oak) for acoustic wells, natural and engineered wood veneers, painted surfaces and laminates for vertical ribs and frames. RPG offers clear lacquer or factory color-matching of wood finishes and paint colors. INSTALLATION Modffractal TM is designed to be flush mounted to a wall or ceiling with factory-integrated blocking. They can be installed singularly or in an array across walls and ceilings.
