How to increase the energy efficiency of buildings using low embodied carbon insulation products.
Gramitherm is an insulating panel made from natural grass. Gramitherm exhibits high thermal capacity, performance and sound absorption properties. Compared with other commonly used insulating materials, Gramitherm offers:
- A negative carbon balance, since the CO2 emitted during the different phases of production and product life is lower than the CO2 captured by the grass during its growth. 1kg of Gramitherm batt absorbs 1,405kg of CO2-eq.
- It is a natural, clean form of insulation both against cold and heat. The product has a thermal conductivity of 0,0405W/m.K, a thermal capacity of 1500 J/kgK and a with a phasing time of 9 hours (240mm). Gramitherm brings a sound absorption of 0,99 at 1000 Hz frequency.
- The energy used in the production of Gramitherm is 20% less than that consumed by insulation products such as extruded polystyrene. Life Cycle Assessment information is available.
Gramitherm costs 85 Euro per m3 (quoted pre-Brexit, please contact Gramitherm for accurate up-to-date pricing information).
