A plant-based, easy to use thermal insulation that is high performing and scalable for safe and healthier indoor environments. It consists of 92% decorticated hemp fibers, grown sustainably in rural communities across the United States and 8% polyester binder.

RESOURCES
HempWool is made of 90% hemp fiber and 10% binder, using a rapidly renewable, plant-based material instead of petroleum-based insulation. Hemp grows quickly, requires relatively low inputs, and supports regenerative agricultural systems. The batt-style panels are designed for wood and metal framing systems with a friction-fit installation that prevents sagging over time.

ENVIRONMENTAL IMPACT
HempWool has a negative carbon footprint, meaning it stores more carbon dioxide during hemp growth than is emitted during manufacturing. With an R-value of R-3.7 per inch, it provides competitive thermal performance, improving building energy efficiency and reducing long-term operational emissions.
Its plant-based composition reduces reliance on high-energy materials like fiberglass and mineral wool while supporting carbon sequestration.

HUMAN HEALTH
HempWool is VOC-free, non-toxic, and non-irritating, making it safe to handle without gloves. Unlike fiberglass, it does not release airborne fibers that can irritate skin or lungs. It is mold-resistant, pest-resistant, and acts as a natural humidity regulator (phase shift regulator), contributing to healthier indoor air quality.

SOCIAL EQUITY
By supporting hemp agriculture, HempWool contributes to more sustainable farming systems and renewable material supply chains. Its safer handling properties also improve job-site working conditions compared to traditional insulation products that require protective gear.
