Gramitherm is the first insulation to be produced from grass, which is sourced from public parks and grass verges, combined with recycled jute fibers, plus a recycled polyester binder, to produce one of the most sustainable forms of insulation on the market and is available from Ecological Building Systems in the UK and Ireland.
Resistant to mold, Gramitherm has natural hygroscopic properties which helps to regulate humidity within the building envelope and enhance breathability. Additionally, Gramitherm sequesters CO2. Each hectare of grass can produce 200m3 of insulation. The production process is also highly sustainable, utilizing heat from biogas, a by-product of grass fermentation, for drying.
Gramitherm is extremely versatile and can be installed in rafters, joists, walls, ceilings and floors. The insulation is both flexible and rigid, ensuring a snug fit, without settlement. It has a high density due to the unique fibrous structure of grass. It is extremely straightforward to install and safe to handle.
Gramitherm has excellent acoustic properties, absorbing 99 per cent of sounds at 1000 hertz, therefore reducing noise transmission. This makes it compatible with creating quiet and comfortable indoor environments.
