Revolutionary Building Material

One Wall.

Not Seven Layers.

Biofill™ is a breathable, carbon-negative monolithic (one) wall system for custom homes. Replacing fiberglass, drywall, formadehyde, sheathing, and vapor barriers with one healthy pour.

For Homeowners & Custom Builders

Too many layers, too little performance.

A conventional exterior wall stacks seven synthetic layers to try to do what one Biofill™ wall does naturally.

Conventional Wall

7 Layers

Too many layers, too many trades.

Conventional walls are prone to mold risks, energy inefficiency, low durability, and high carbon footprints.

Off-gassing · thermal bridging · mold-prone · short life span

Biofill™ Wall

1 Layer

Monolithic hemp-lime pour

Insulation, sheathing, air barrier, thermal mass, and interior substrate - in one breathable, load-supporting wall.

Zero VOCs · self-regulating humidity · Class A fire · 100+ yr lifespan

The result: fewer trades on site, fewer failure points in the wall, and a home that gets stronger over time.

For Custom Home Builders & Precast Manufacturers

Biofill™ pours from a standard mixer, sets in 45 minutes, and eliminates weeks of tamping or specialty crews. Delivering healthier homes at the same installed cost as conventional stud-frame construction.
