Delta Drop® 2×4

Delta Drop® 2x4 brings faceted, dimensional geometry to your design, in a long, narrow panel. Plus, it offers easy installation, using quick torsion spring attachment across standard ceiling grid systems, or simple wall attachment using our Vertika channel system. Integrated backlighting is available if you want to add some light to your design, or try our Soft Sound® backer if you are looking for an acoustic solution. 


Key Features

  • Acoustic Performance

    Delta Drop®'s optional Soft Sound® backer material reduces the impact of noise from everyday annoyances like ringing, typing, and chatter resulting in a more pleasant and productive environment. The Soft Sound® backer works in concert with the design to help reduce and control reverberations leaving a lasting impression at scales ranging from assembly halls to to conference rooms.

  • Multiple Pattern Options

    Delta Drop® panels are preconfigured faceted solutions designed with a dynamic array of criteria and effects in mind. Choose from our library of patterns to uniquely impact your project.

  • Multiple Panel Types

    In addition to multiple patterns, select from various panel types including Standard, Transition, and Flat Panels. Use them together to create gradations and increase the aesthetic and functional versatility of the system

  • Easy Installation & Access

    Delta Drop® panels offer easy install and access across walls and ceilings through quick torsion spring attachment to standard grid systems and a simple hook-on attachment to our Vertika® channel system.

  • Design with Standard Panels

    We make it easy to create stunning faceted designs on a standard torsion grid. Mix and match our available panel sizes in stepped or continuous configurations. Choose from our library of patterns or create one that fits the unique needs of your project.
