...a mixture of insulating particles, hydrogen peroxide, starch, and water [poured] 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, says Bayer, the son of a successful Vermont farmer.
Greensulate acheives an R-value of about 2.7 per inch, which is similar to conventional insulations. And, unlike conventional insulations, Greensulate is biodegradable. Read more at Keetsa. (photo by AP Photo/Mike Groll)
