The Primacoustic StratoTile 24 x 24" T-Bar Acoustic Panel (12 Pack) is a high-performance black ceiling tile designed to fit into existing T-Bar systems. It is made from high-density glass wool for added absorption in the critical voice range. This helps improve intelligibility by attenuating flutter echo and reducing first order reflections. The StratoTile features 3/4" thick (20mm) high-density 6lb per cubic foot glass wool constriction for maximum sound absorption and is encapsulated in fine micromesh with sealed edges to retain the minute glass fibers. The front surface is finished in black latex but can be repainted to suit. Each tile installs into ceiling tile frames that accommodate 24 x 24" tiles. These tiles feature a "trim" edge that mounts the tile flush against the ceiling tile frame.

Unlike low-cost mineral wool tiles, StratoTiles will not sag due to moisture. This makes them particularly well suited for use in regions with fluctuating temperatures and humidity levels. StratoTiles have been fully tested to meet ASTM-E84 fire and smoke development requirements for Class-A designation and safe use anywhere.

Once in place, StratoTiles work with the air space above the panel called the plenum to absorb all frequencies down to 125Hz delivering a truly linear performance throughout the voice range. This makes StratoTiles well suited for installations in call centers, boardrooms, offices, restaurants and classrooms where excessive reverberation and echo inside the room can make conversations difficult.
