Gramitherm: The Local Biobased Insulation Making a Difference


Gramithem

In the vast world of eco-friendly construction materials, Gramitherm stands out with its unique innovation: a biobased insulation made from grass. Yes, you read that right—grass from the mowing of waterways and highway edges is transformed here into a sustainable resource for insulating our buildings. This innovative product combines waste recovery with technical performance tailored to the current needs of the construction industry.


A Swiss Invention Taken Forward with Passion

Originally, Gramitherm was invented by Stefan Grass—an aptly fitting name for a grass-based technology, isn’t it? It's no coincidence that this natural product was brought to life by him. Today, thanks to the dedication of a passionate couple, Christian and Agnès, later joined by Florent, the technology has been revived and developed locally in Charleroi. The company has become a pioneer in the industrial production of biobased insulation materials.


The Benefits of Biobased Insulation

Gramitherm shares several advantages with other eco-friendly insulation materials, such as:

  • Summer Comfort: Its ability to keep buildings cool during heatwaves is a key asset for improving occupants' well-being.

  • Thermal Lag: It slows down the penetration of heat into the building, providing enhanced thermal comfort.

  • Moisture Regulation: Gramitherm regulates indoor humidity by absorbing and releasing moisture, contributing to a healthier indoor environment.


A Circular and Virtuous Resource

What truly sets Gramitherm apart is its virtuous production cycle. By recovering plant waste, grass, often seen as useless, the company transforms this material into a sustainable and high-performing insulation. This approach enables carbon storage in buildings, reducing their ecological footprint over the entire lifespan of the insulation.


Technical Performance Fit for Today’s Needs

In addition to its ecological qualities, Gramitherm offers sufficient technical properties to be integrated into most building systems:

  • Fire Resistance: While not the top insulator in the market on this point, it meets the necessary fire safety requirements for most projects.

  • Sound Absorption: Gramitherm contributes to acoustic comfort by absorbing sound, creating more pleasant living spaces.
