mushroom insulation: renewable and green
Eben Bayer and Gavin McIntyre have formulated a renewable source of sustainable insulation from mushrooms that also acts as a firewall. Their studies at Rensselaer Polytechnic Institute, Troy NY, led to their new product 'Greensulate'.
The green insulation is created by pouring a mixture of insulating particles, hydrogen peroxide, starch, and water into a panel mold. Mushroom cells are then injected into the mold, where they digest the starch producing a tightly meshed network of insulating particles and mycelium. The end material is an organic composite board that has a competitive R-Value a measurement of resistance to heat flow (firewall).
Conventional insulation is neither eco nor renewable, so the duo have a promising development on their hands.
