With Logix™ Brand Integrated Ceiling Systems from USG, you can design ceilings that meet building requirements without being constrained by the limits of traditional acoustical ceilings. Logix transforms visual distractions such as lighting, air vents, and other utilities into dramatic design elements by concentrating these fixtures on narrow bands that run the length of a ceiling. This allows for open ceilings that are uncluttered by ceiling utilities.

A wide selection of acoustical and specialty panels as well as corresponding suspension system components and accessories are available to enhance and customize your design. Plus, with a wide selection of Logix partners, you can be assured that ceiling utilities will complement your design and integrate seamlessly into the ceiling.

This guide is a comprehensive resource for the critical dimensions of a Logix Integrated Ceiling System.¹

¹ The USG Logix yoke is an optional suspension system installation accessory that facilitates the spacing and suspension of parallel main tees with one hanger wire. The Logix yoke is compatible with both metric and imperial utility channel sizes. The yoke also keeps hanger wire wraps away from linear luminaires and can reduce the number of hanger wires required. The yoke also helps to brace the utility channel.
