Problem Addressed

How to increase the energy efficiency of buildings using low embodied carbon insulation products.

Solution Overview

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 low carbon material. 1kg of Gramitherm batt absorbs 1,405kg of biogenic carbon during the growth of the grass. 
  • 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).
