Combine structural strength, architectural freedom, and environmental excellence with three prefabricated TimberROC® wood-based concrete systems. Fast installation and high industrial quality ensure full control of both schedule and costs.
CS2 – TimberROC® load-bearing wall with integrated concrete reinforcement
As a primary structural solution, the CS2 system combines the lightness and strength of TimberROC wood-based concrete. Prefabricated panels leave the plant ready for reinforcement placement and casting of vertical and horizontal tie beams — saving time on site while ensuring full structural continuity.
With the CS2 system, you get a ready-to-use low-carbon wall that supports the structure while providing optimal hygrothermal comfort inside the building — one panel, multiple functions!
Applications
For residential, multi-family, and commercial buildings up to four storeys; vertical extensions possible.
Public buildings (categories 1 to 5), industrial or agricultural facilities up to 8 m high.
Seismic zones 1 to 4 and wind zones 1 to 4 in France.
Complies with ATEx case A n° 3044_V3 (CSTB)
Construction and operation benefits
- Fast installation: integrated lifting anchors and optimised panel layout.
- Controlled quality: licensed production under CCB Greentech supervision.
- Poly-finishing: rendering, ETICS or ventilated cladding.
- Low maintenance: rot-proof, frost-resistant, and insect-resistant material.

FP2 – TimberROC® self-supporting (non-load-bearing) wall panel
The FP2 system is a prefabricated wood-based concrete panel designed to be fixed onto an existing post-and-beam structure. Each panel rests on the one below, forming a continuous, biosourced façade. Ready for rendering or cladding, it is installed after the main structure is completed — without extending the project timeline.
The FP2 combines lightness, thermal performance, and fast installation — a façade that speeds up construction without compromising on carbon impact.
Applications
- Suitable for residential and multi-family buildings up to four storeys, and public-access buildings (categories 1 to 5).
- Also applicable to non-residential, industrial, or agricultural buildings up to 8 m high.
- Approved for seismic zones 1 and 2, and wind zones 1 to 4 in France.
- Compliant with CSTB ATEx Case A No. 3152_V1.
Construction and operation benefits
- Sequenced installation: fitted after concrete pouring — zero interference with the structural works.
- Industrial precision: controlled tolerances, integrated edge strips and rebates.
- Architectural flexibility: spans up to 7 m, multiple finishes.
Low-carbon performance: ready-to-use façade solution meeting RE2020 requirements up to the 2031 threshold.**

FP3 – TimberROC® façade anchored to the slab edge (non-load-bearing)
The FP3 principle uses the TimberROC® panel, but attaches it directly, level by level, to the slab nose of the concrete shell.
Used in the structural work cycle, it enables :
speed up work by secondary trades,
a clean, controlled worksite,
a high-performance carbon envelope.
The panels are prefabricated in the factory, delivered just-in-time, then secured with anchor brackets.
Applications
- Residential buildings: single-family or multi-family (types 1 to 3, categories A and B)
- Non-residential buildings
- Public-access buildings (ERP): categories 1 to 5
- Industrial or agricultural buildings: up to 8 m high
- Seismic zones 1 to 4
- Wind zone in France from 1 to 4
RE2020 project and Bâtiment biosourcé label
Conforme ATEx cas A n° 3152_V1 (mêmes règles que FP2).
Construction and operation benefits
- Implementation according to the structural work cycle
- Casting of the N+1 floor slab against the facing edge of the level N panels, with a rock wool insulation layer.
- Connection with mounting brackets
- Integrated slab and column plates
- Rockwool between panels, and between panels and concrete structure
- PU foam on both sides of each post
