It is combined with recycled jute fibres and a recycled polyester binder to produce one of the most sustainable forms of insulation on the market.

Ecological Building Systems, a supplier of natural building products for sustainable construction, has introduced this exciting sustainable insulation to the UK and Ireland.

Resistant to mould, Gramitherm has natural hygroscopic properties, which help regulate humidity within the building envelope and enhance breathability.

The innovative product has secured an Environmental Product Declaration (EPD). It demonstrates that 1kg of Gramitherm sequesters 1.5kg of CO2, equivalent post-production, making it a highly efficient and eco-friendly insulation choice.

In addition to an EPD, Gramitherm holds European Technical Approval, which confirms compliance with relevant standards, sustainability credentials, and low environmental impact.

Gramitherm is carbon negative (cradle to gate) and has achieved A+ ratings in VOC (Volatile Organic Compounds) emission tests as a natural, sustainable product. Highly sustainable, each hectare of grass can produce 200m³ of insulation.

Containing over 90% bio-based content, Gramitherm materials are sourced from within 300km of the manufacturer, reducing transport emissions and lowering its carbon footprint. The production process is also highly sustainable, utilising heat from biogas, a by-product of grass fermentation, for drying.
