Mushroom Insulation For Tiny Homes

“We’re not just building a tiny house, we’re growing it. That’s right, the Mushroom® Insulation in the walls is literally alive and growing. This is a radical test of Ecovative’s building materials that are under development.

    Ecovative uses mycelium (mushroom “roots”) to bond together agricultural byproducts like corn stalks into a material that can replace plastic foam. We’ve been selling it for a few years as protective packaging, helping big companies replace thousands of Styrofoam (EPS), EPE and other plastic foam packaging parts. We’re now working to develop new products for building materials. This is an exciting, radical and innovative approach to try a bunch of ideas, learn a lot, and grow something really awesome.

   Here’s how it works. Mushroom Insulation grows into wood forms over the course of a few days, forming an airtight seal. It dries over the next month (kind of like how concrete cures) and you are left with an airtight wall that is extremely strong. Best yet, it saves on material costs, as you don’t need any studs in the wall, and it gives you great thermal performance since it’s one continuous insulated wall assembly. The finished Mushroom® Insulation is also fire resistant and very environmentally friendly. …”

    How cool is that?!!

    cool? i would not touch it. i have so many allergies, hard time believing this would be good idea.

    in about fifty more years i will give it a "look see".

    I think this type of experimenting is awesome.
    To Anonymous – this not mold, this is mycelium, essentially the root structure of a mushroom. Once dried, it's no longer living and probably not much different than using woodchips, sawdust or cellulose. Even wood is dried living matter (OMG – wouldn't put that in my walls!)

    The idea of growing a house is one we might all have to embrace one day. Killing living trees to produce houses ( or worse, paper) the way it is done now, bring about its own issues ( and may indirectly be causing a lot of the allergies people face today).

  4. is the end product eaten by any insects?

  5. Love this, so much! <3

    ah..okay, not living, but still have my concerns…

    at the very least, if one did this, and hard times hit, might one be okay to eat it/as one eats dried mushrooms? — really, not being smarmy…if it were still okay to eat..insects also might find it tasty.

    If hard times hit, perhaps the last thing you would consider is eating the walls of your shelter!
    I'm sure dried mycelium is about as palatable to humans as eating straw.

    As for insects, well, I think we should be worrying about the building materials we use that are not palatable to anything at all and therefore would never break down or not in a period of time that humans can understand.

    I think all carbonaceous materials are food for something. That includes us!

    But like wooden buildings today, we have ways to mitigate the consumption of our homes by insects. Same rules would apply here, I would think.

    The real advantage here is that the 'material' is induced to grow to the form desired rather than being harvested, shaped in factories and then transported. Of course, the substrate still has to be moved and it's questionable whether the mycelium growth can occur on site (ie: in any conditions), so it's probably still limited at the moment.

    to daltxguy, sure enough, wouldnt be good to eat one's shelter…grin…

    all the rest is good points, however, me, i am still a hard sell, ……………..

    wonder what the fire rating/sound proof value/durability, etc..? ah well, in time no doubt that too will be posted/news.
