G-Brick-Eco is a structural insulation panel made of plywood and an eco-insulation material that can be used for load-bearing walls and internal partitions, roofs and ceiling parts in wood construction of conventional buildings and tiny houses. It allows for very short construction times, the panels are very cost, energy and resource efficient. The innovation is based on the improvement of the panel’s core materials and on the enhancement of its design so that it can be used in high structural applications. The core insulation material of G-Brick-ECO is an ecological wood-based product, replacing the commonly used extruded polystyrene. In addition, wooden ribs in the core were included, to make it structurally more resistant and enlarge product’s working range.

Innovation details

Benefits / Impacts

- G-Brick-Eco panels are load bearing and thermally insulated building wall elements allowing for very short construction times both in renovation and new built.
- Suitable for diffusion-closed construction systems.
- Easy handling on site.
- Fire resistance for low- and midrise buildings.
- The mechanical resistance is enhanced by vertical ribs rigidly connecting both plywood surfaces
- When compared to competing products such as Cross Laminated Timber (CLT), G-Brick-Eco is much more cost, energy and resource efficient"

Technical Features

Two prototypes have been proven: 1) G-Brick with ribs and low-denisty bio-insulation material by VTT, 2) G-Brick without ribs and high-density insulation material from SOPREMA

Next steps, R&D needs

Potential improvements can be made by increasing the efficiency of the production process especially regarding the 2-steps of gluing ribs and insulation into the panel. Next steps :
1) Process optimization,
2) Ribs adhesion process,
3) Automation of the production process.
