The details carry the design.
At R.L. Turner High School, SectisDesign Linear brings a warm wood tone to the ceiling and wall surfaces. Suspended ring lights sit below the ceiling, making its repeating lines part of the space's character.
GMB supported installer Tri Phase Interiors as the project team worked through SectisDesign Linear finish samples, backing options and ceiling-panel layouts.

Design intent
Keeping the wood tone continuous
The designer's intent was a consistent wood tone across the slats and the surface behind them. Sample review brought the exposed laminate finish and the backer finish into the same conversation: each affects how the linear system reads from below and across the room.
The team reviewed matte and fine-velvet laminate samples alongside wood-grain and acoustic backing options. Keeping those choices distinct helped frame the questions for the designer and manufacturer.
Installer coordination
Making the ceiling layout fit
Ceiling sections varied with existing column locations, and revised reflected ceiling plans changed the dimensions the team needed to work with. Panel lengths, the placement of joints and the supporting grid all needed to be considered together.
The coordination included a manufacturer proposal for paired shorter panels with a centered reveal, along with the support-spacing review that approach would require. These discussions show the work behind translating a continuous linear design into individual ceiling bays.
