HempWool
What it does
HempWool® is a natural-fiber batt insulation produced by Hempitecture in Idaho from U.S.-grown industrial hemp. It delivers competitive thermal performance with the moisture-resilience, sound-dampening, and indoor-air-quality benefits that distinguish plant-fiber insulation from petrochemical and stone-wool alternatives.
Pre-cut to fit standard 16″ and 24″ on-center cavities in both wood and light-gauge-steel framing, HempWool installs cleanly with a serrated knife and friction-fits between studs without itch, dust, or off-gassing.
When to use it
- Exterior wall cavities in framed construction (wood or steel)
- Above-grade and basement walls
- Floor and ceiling assemblies
- New construction and retrofits where IAQ matters
- Projects targeting carbon-negative material specs
Key benefits
- Carbon-negative — sequesters more CO₂ than is emitted during production
- Class A fire-rated; no added flame retardants
- Naturally moisture-resilient — does not rot, mold, or attract pests
- Sound absorption competitive with stone wool at equivalent thickness
- Non-toxic and biodegradable; safe to handle without PPE
- VOC-free; meets ASHRAE 62.2 indoor air quality criteria
Format
Pre-cut natural hemp-fiber batts in 16″ O.C. (15.25″ wide for wood, 16.25″ for light-gauge steel) and 24″ O.C. (23.25″ wide for wood, 24.25″ for light-gauge steel), available in a range of thicknesses.
