Modern engineered material perfectly suited for CNC manufacturing. Engineered to prevent edge chipping and fiber tear-out in CNC applications, to be carbon-negative. Non-structural decor elements lasting 100 years. Easy instalation. Lower cost comparing to Oak or Stone.
Grüneholz Engineered Hemp Hardwood is a dense industrial composite material developed for precision CNC machining
and dimensional stability in premium interior applications.
Designed as an engineered alternative to solid oak, it enables repeatable industrial production while maintaining
structural consistency and machining accuracy.
Sharp milling results with minimal fiber tear-out. Suitable for high-detail architectural components.
Engineered structure minimizes movement under humidity and temperature variation.
Reduced transport load and easier on-site handling compared to solid oak.
Consistent density and performance across batches. Optimized for scalable manufacturing.
Developed using renewable hemp fibers within an engineered composite matrix.
Architecture-grade material direction with manufacturing-first thinking (not artisan craft).
Black & white base. Large uppercase typography. Generous whitespace. Industrial workshop photography. Subtle fade only — no heavy gradients, no loud effects.
We are onboarding a limited number of development partners for 2026 pilot projects. Partners receive early production access, prototype collaboration, and direct technical support during integration into architectural and manufacturing workflows.
