Baffles & Clouds — Acoustic Material Guide
Suspended acoustic baffles and cloud panels hang below the structural soffit to absorb sound on both faces. They are the go-to solution when exposed services, ductwork, or structural elements prevent a continuous suspended ceiling. Available in mineral wool, polyester, metal, and fabric-wrapped formats.

Installation Notes
Baffles and clouds require structural fixings to the soffit and must be suspended at least 200mm below the deck for optimal performance. Spacing between baffles typically equals baffle depth for maximum absorption efficiency.
Typical thickness: 40-100mm
