DONN® FINELINE® DXF/DXLF Acoustical Suspension System
-
A premium yet economical monolithic ceiling look. This ceiling suspension system provides aesthetics with the low cost, quick installation and access benefits of standard exposed grid. Hot-dipped, galvanized steel inhibits rust. DONN FINELINE High Recycled Content (HRC) is now available as part of the standard acoustical suspension system offering.
The DONN FINELINE ceiling suspension system provides a premium monolithic ceiling look and a narrow slotted profile with all the benefits of standard exposed grid, including low cost, quick installation, and easy access.
DONN acoustical and drywall suspension systems have the highest average recycled content in the industry. In fact, many of the components are available with High Recycled Content (HRC). HRC suspension components are classified as containing over fifty percent total recycled content. Total recycled content is based on product composition of post-consumer and pre-consumer (post-industrial) recycled content per FTC guidelines. Look for the green symbol on data pages to quickly identify HRC components.
Its narrow slotted profile, with a 9/16" wide face and a 1/4" reveal, hides the suspension system behind acoustical panels, yielding a smooth, clean ceiling plane with minimal exposed metal. Its 1/4" slot accommodates partition attachments and pendent mounted light fixtures. It accepts Celebration™ metal ceiling panels without requiring grid system changes.
Mitered intersections give FINELINE grid the crisp architectural detailing preferred in today’s office environment, and its all-steel construction means strength and dimensional stability at low cost. The system integrates with standard 24" x 24" or 24" x 48" lay-in light fixtures and standard lay-in air handling devices.
Grid components are connected with plug-in positive-lock insertion for quick installation. Main tees are available in both intermediate and heavy duty, and in 1-1/2 hour floor/ceiling UL fire-rated design G264, and 1 hour roof/ceiling UL design P254 in a 24" x 24" module size. USG M9 wall angle and MS 174 shadow molding with 9/16" flange coordinate the perimeter with the narrow FINELINE face. NOTE: An M7 wall angle must be used in fire rated installations.
The optional DONN Air Diffuser provides a clean, uninterrupted ceiling plane, supplying conditioned air to the modern office environment, while complementing the FINELINE system.
The system meets or exceeds all national code requirements, including seismic and load compliance specifications per ASTM C635.
