Middle Atlantic AUO22PT1G1SLG ORI Acoustic Ceiling Tile — Plateau 1, Silver Gray
Overview
The AUO22PT1G1SLG is a 2' x 2' acoustic ceiling tile from Middle Atlantic's ORI acoustic ceiling tile system, finished in Silver Gray with a Plateau 1 surface profile. Built from 100% PET Felt polyester, it drops into standard 15/16" exposed-grid layin ceilings — the most common commercial grid type — making it a direct fit for conference rooms, AV equipment rooms, and open office deployments where acoustic performance and a clean finished ceiling are both required. At 2 in. (5.1 cm) height and 2 in. (5.1 cm) width per tile, the Plateau 1 profile sits low relative to deeper acoustic modules, so it works in spaces with limited ceiling plenum clearance. The Silver Gray colorway integrates with standard commercial ceiling mount and grid hardware without requiring custom finishing. If you're specifying a full technical furniture or rack enclosure installation with overhead cable management, these tiles maintain the room aesthetic while providing sound absorption above the workspace.
Compatibility
Designed for use with the Middle Atlantic ORI acoustic ceiling tile system. Requires a standard 15/16" exposed-T layin ceiling grid — the tile rests in the grid without additional hardware, so no tools or fasteners are needed for basic installation. Not compatible with 9/16" narrow-bar or concealed-spline grid systems. Verify your existing grid bar width before ordering; the 15/16" layin spec is non-negotiable for a flush drop-in fit. For spaces using acoustic panels alongside equipment racks, confirm the ORI system tile depth (2 in.) clears any recessed lighting fixtures or above-ceiling cable trays in the same grid bay.
Installation Notes
Drop-in layin installation requires no adhesive, fasteners, or special tools — lift the tile and set it into the 15/16" T-bar grid. Confirm grid opening dimensions match the 60.33 x 60.33 cm (nominally 2' x 2') tile footprint before installing. PET Felt material is lightweight, which reduces handling fatigue during large-area installs but also means tiles can shift if subject to airflow pressure from nearby HVAC diffusers; position accordingly.
