Features of decorative acoustic ceilings
Dual-Sided Sound Absorption · Unobstructed Plenum Airflow · ASTM E84 Class A Fire Rated
A lightweight, vertically suspended acoustic blade system engineered for high-ceiling architectural volumes and exposed open-plenum structures. With both faces exposed to ambient sound fields, these 100% recyclable polyester baffles deliver superior sound absorption per square foot of ceiling area—eliminating flutter echoes while maintaining unobstructed clearance for HVAC ducts, fire sprinklers, and linear pendant lighting.
Dual-Sided Sabine Absorption
Both faces and exposed edges actively capture rising sound waves, providing up to 2.2× higher acoustic absorption efficiency than flush ceiling tiles.
Zero HVAC & MEP Obstruction
Vertical parallel blade orientation permits uninhibited thermal convection, return-air circulation, and compliant fire sprinkler discharge coverage.
Ultralight Overhead Safety
Weighing only ~1.5–3.2 kg per blade, PET baffles impose minimal structural dead load on open-web steel joists and standard ceiling grid wires.
ASTM E84 Class A Fire Rated
Strict commercial fire compliance (Flame Spread < 25, Smoke Developed < 450) required for public transit hubs, schools, and offices.
