Ecological system
The Gramitherm® production process involves the extraction of cellulose fibers from the grass, with the remaining juice used to produce bio-gas or as a nutritional concentrate for animals. This ensures that all the components of the grass are fully utilized without creating waste.

Primary raw material: grass
Natural, “residual”, local grass (wetlands, canal margins, airports, nature reserves...)
Sufficient quantities of available raw materials
From 1 ha of grass, 200 m³ of Gramitherm can be produced and 3 to 4 houses can be insulated.
Material origin
Gramitherm® insulation panels consist of more than 90% natural materials, making them one of the most environmentally friendly options for insulating buildings. In addition to thermal insulation, they also provide effective protection against summer heat, absorb sound efficiently, maintain constant humidity, and are resistant to fire and mould.

Made in the EU
Bio-based thermal insulation material manufactured in Belgium (Sambreville).
Local resources
The production cycle uses regional resources to produce for local markets (short supply chains).
Carbon footprint
The production of Gramitherm® has a negative carbon footprint; 1 kg of product absorbs 1.5 kg of CO₂ equivalent. Grass is a rapidly renewable resource that does not require ploughing or costly treatments nor chemical spraying, contributing to the sustainability of the product.

Sufficient production capacity
Production capacity 200.000 m³/year. Potential to build additional capacity nearby in case of significant local interest.
Universal use
Gramitherm® is suitable for a variety of building and renovation applications such as floor, wall and roof insulation. It is easy to process, free from irritants and resistant to mould growth, making it a healthy choice for indoor environments.
Contact usUse on roofs
Does not contain irritants
It is not allergenic.
No risk of allergic reactions or irritation of mucous membranes already during installation.
Use in floor and ceiling
Grass fibers are naturally resistant to moisture and biodegradation.
The material retains its volume and insulating properties for many years.
The ability to self-dry reduces the risk of moisture build-up that could lead to degradation.
Use as a wall
It has high resistance to mold and biological pests.
Its natural ability to self-dry extends the life of the material.
