Gavin McIntyre, and Eben Bayer invented Greensulate in 2006 when they were seniors at Rensselaer Polytechnic Institute in Troy, N.Y.
It’s organic, biodegradeable and the ingredients are simple: water, flour, oyster mushroom spores and perlite.
It is also highly fire-resistant, especially compared to your typical foam insulation
They are currently testing to make sure that mold does not grow even when saturated with water.
“The 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 result is an organic composite board that has a competitive R-Value a measurement of resistance to heat flow and can serve as a firewall.”
