As building systems are increasingly integrated into the ceiling, building owners and service providers require ready access to the space. Echelon from Hunter Douglas provides both noise reduction and swing-down access to the plenum. The acoustical ceiling system features a noise-reduction coefficient of 0.85, and its panels measure up to 4’ square. Echelon contains up to 30% recycled content and is Greenguard certified. Available in white as well as a range of colored, wood, and textured finishes.
