Open-grid wood ceiling systems with blade spacing configured to your acoustic and design requirements.

Grille panels are the most recognized form of architectural wood ceilings. Vertical wood blades hang perpendicular to the ceiling plane, creating a rhythmic pattern of solid wood and shadow that changes character with the light throughout the day.

Penner grille systems are built to your project’s specifications. Blade width, depth, spacing, and species are all configurable. Need tighter spacing for higher NRC performance? Wider gaps for airflow and sprinkler access? A custom profile that doesn’t exist in anyone’s catalog? That’s standard work for us.

Every panel ships pre-assembled, factory-finished, and ready for field installation. No on-site staining, no alignment guesswork, no wasted labor.
