Mach 4 - Flat Wood Ceiling Panels

Wood wall and ceiling system in an architectural project

Mach 4 – Flat Panels

Flat panels are the most common architectural wood ceiling. Real wood, flush to the ceiling plane, no visible mechanical systems. The look is clean. The engineering is straightforward.
Penner builds flat panels in three configurations within one product family:
Standard (Mach 4) is the solid wood surface. No perforations, no slots. Use it where absorption isn’t required or where a continuous wood plane is the priority.
Perforated (Mach 4.1) adds precision-drilled holes backed by acoustic fleece. Sound passes through the perforations and gets absorbed by the backing material. Hole diameter and spacing are configurable to hit your NRC target.
Slotted Acoustical (Mach 4.2) uses linear groove patterns on the face with backside perforations for higher NRC performance. The grooves add a textured look while the dual-mechanism construction (face slots plus back perforations) increases absorption beyond what either approach achieves alone.
Same core construction and attachment methods across configurations. Switching from standard to perforated doesn’t restart your timeline or change your install method.

Documentations

Panels lay into grid systems, clip to concealed rails, or screw to direct-mount substrates. Each panel arrives factory-finished with attachment hardware installed and configuration marked, so the installer isn’t making decisions in the field.

The same panel construction works on ceilings, walls, and transitions. One scope, one finish standard, even when the ceiling turns a corner and runs down the wall.

Lead time note: custom perforation patterns and non-standard panel sizes add 2-3 weeks beyond standard configurations.

Multiple North American hardwood species available. Every configuration can be stain matched to your project’s color palette. Finish is applied in controlled conditions so perforated, slotted, and standard panels installed side by side match in color and sheen.

Send us your drawings. We’ll recommend the right configuration and quote it with specs and lead times.
