Building Insulation

The Future of Sustainable Insulation

Myco Foam, now proven to replace plastic foams for protective packaging, is coming next to insulation. Today's most common insulation materials have some serious negative environmental consequences. We're developing natural, rapidly renewable Mushroom® Insulation as a healthy, easy to install insulation product that performs.

Cradle to Cradle CertifiedCM is a certification mark licensed by the Cradle to Cradle Products Innovation Institute.

We Grow Insulation


Ecovative offers an R-value guarantee; unlike plastic foams, the aged R-value of Mushroom Insulation will not decrease over time.

Mushroom Insulation is intended for above-grade applications and should be protected from weather similarly to wood.

Coming Soon: Insulated Sheathing

Myco Foam Insulated Sheathing can be used on new construction or retrofits to meet requirements for continuous insulation (CI) or to meet deep energy retrofit goals. Continuous insulation increases thermal performance without any thermal bridging, and taped seams create a continuous air barrier for greater energy efficiency. Mushroom Insulation is bonded to a weather resistive barrier, allowing for use as a drainage plane under siding, and protecting your building from moisture problems.

In Development

We see great potential for Mushroom Insulation to be used in a wide range of products and building methods. Click below to get a peek at what we're working on.

Acoustic Panels and Ceiling Tiles

Mushroom Acoustic Panels and ceiling tiles have ultra low VOC emissions, no chemical binders, and offer excellent sound dampening to making your space look and sound great. Panels can be produced in standard or custom sizes and designs to fit your high-end eco-interior.

Structural Insulating Panels

A lot of smart designers and builders appreciate the quick assembly and high performance walls that are made possible by structural insulated panels (SIPs). Many people have concerns about the environmental consequences of a house with walls that are entirely filled with EPS or Urethane foams. Mushroom Insulation can provide comparable strength and insulating performance, with a lighter environmental footprint. Furthermore, Myco Foam is more thermally stable as compared to plastic foams. So joints between Mushroom Insulated SIPs are less likely to open up over time, resulting in a tighter building envelope.

Exterior Insulated Finishing Systems

Exterior Insulated Finishing Systems (EIFS) generally consist of EPS adhered in a continuous layer to the sheathing of a building, and then covered in a durable and aesthetic stucco type product. During the process of installation, EPS is rasped, which results in little EPS beads and fragments that often blow into the environment and onto neighboring properties, where they cannot be cleaned up. With Mushroom Insulation used in EIFS, rasping would make mulch, not pollution. The superior thermal stability and flame resistance of Mushroom Insulation show promising potential for use in EIFS.

Loose Fill Mushroom Insulation

Loose fill cellulose insulation (which is made from recycled newspaper) is often touted as one of the greenest forms of insulation available today. In order to meet fire code, manufacturers have to add expensive chemicals so that the paper based insulation won't go up in flames. Mycelium is naturally fire resistant. We're working on methods of growing a fire resistant insulating mycelium coating on loose fill particles as a drop in replacement for standard cellulose insulation.

Grow-In-Place Mushroom Insulation

What if you could literally grow a house, or at least the insides of the walls? The Ecovative team has been playing around with that idea, growing Mushroom Insulation right inside of walls, rather than with our standard factory equipment. Properly engineered wall assemblies can be filled with live Mushroom Insulation and grown in-place under controlled conditions. The insulation solidifies, sets, and dries out over the course of about a month. The result is an airtight, highly insulated structural wall assembly without the ecotoxicity and global warming impacts associated with spray foams. We believe that this radical construction method has exciting potential for a revolutionary new pre-fabricated building system, but it is not appropriate for renovations or outdoor construction.

And More!

Insulated metal panels, door cores, architectural elements, modular office walls, and more are possible with Mushroom Materials. Ecovative aims to partner with leading companies to develop and bring these disruptive innovations to market.

Ecovative is also developing Myco Board, a tree-free and formaldehyde-free alternative to engineered wood products like particle board and fiber board.
