In Chile, a company called Rootman has created wall insulation made from 100% biobased materials that also resists fire up to one hour.

Dubbed Radicular Mattress, the material is made from the seeds of various plants produced via hydroponics. According to the company, the seeds can be produced in all weather and do not require large amounts of water.

Rootman General Director Roberto tells InterestingEngineering.com the material offers more thermal protection than expanded polystyrene and polyurethane, the most effective insulators on the market. “[Also], Styrofoam burns in three seconds, followed by fiberglass at 15 seconds and polyurethane in 1 minute, [while] the [Radicular Mattress] burns in 60 minutes,” he adds. The material is produced in Los Angeles, Chile.
