Product Description

Sonex® Harmoni Ceiling Tiles are the natural choice when looking to combine contemporary styling with excellent acoustical control at a moderate price.

The Sonex® Harmoni ceiling tiles are manufactured from a Class 1 fire-rated acoustic foam. Choose from a smooth flat pattern or a slightly sculpted appearance. These ceiling tiles are painted with an HPC coating for a durable clean look. Install these ceiling tiles by simply dropping them into any standard T-bar suspended ceiling grid system.

These are a perfect solution for classrooms, listening rooms, home theaters, conference rooms, retail stores, and any other interior areas where ceiling tiles are used.
