Gramitherm awarded the Solar Impulse Label
Gramitherm®, an innovative natural insulation made from grass fibers, has been granted the prestigious “Solar Impulse Efficient Solution Label” by the Solar Impulse Foundation. This international distinction, initiated by explorer Bertrand Piccard, rewards solutions that combine positive environmental impact with economic viability.
What is the Solar Impulse Label?
The Solar Impulse Efficient Solution Label was launched in 2018 by the Solar Impulse Foundation, created by Swiss explorer and scientist Bertrand Piccard. Its mission: to identify and promote more than 1,000 profitable solutions that help protect the environment.
Unlike many purely environmental labels, this certification is based on a rigorous evaluation process carried out by independent experts. Projects are assessed according to three main criteria:
- Technical feasibility
- Positive environmental impact
- Economic profitability
Only solutions that meet all three requirements are awarded the label, making it a mark of credibility and international recognition.
Why was Gramitherm awarded the label?
Gramitherm® stands out for its uniqueness: it is the first thermal and acoustic insulation material made from grass fibers. This innovation offers several key benefits:
- Ecological: bio-based, recyclable, durable (over 50 years), with a very low carbon footprint.
- Local: manufactured in Wallonia (Belgium) from an abundant and renewable raw material.
- High performance: certified with a European Technical Assessment (ETA) and an Environmental Product Declaration (FDES) listed in the INIES database.
- Circular economy: production valorizes a natural resource that is often underused.
These qualities convinced the Solar Impulse Foundation to grant Gramitherm® the label, confirming both its environmental and economic relevance.
The benefits of this recognition
Receiving the Solar Impulse label provides Gramitherm® with:
- Stronger credibility among construction professionals, architects, and investors.
- Increased international visibility, thanks to its inclusion in the foundation’s selection of sustainable solutions.
- The opportunity to join a community of innovators and decision-makers committed to ecological transition.
This label acts as a trust mark, opening the door to new partnerships and broader market adoption.
A step forward for sustainable construction
For Bertrand Piccard, founder of the Solar Impulse Foundation, “today there are solutions capable of protecting the environment while remaining profitable.” Gramitherm® is a perfect example of this vision.
By joining the network of labeled innovations, grass-based insulation proves that it is possible to build and renovate differently, combining energy performance, sustainability, and cost-effectiveness.
Conclusion
The Solar Impulse label marks a major milestone for Gramitherm®, strengthening its position as a pioneer in bio-based insulation. More than just a material, it is a solution for the future of a building sector in ecological transition.
