You GREW a House?! (Yes… and so can you!)
We didn’t just build a tiny house, we grew it. That’s right, the Mushroom® Insulation in the walls were literally alive and grew in place. This is a radical test of Ecovative’s Mushroom® Insulation.
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), and other plastic foam packaging parts. We’re now working to develop new products for building materials. This project 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.
