Hemp Hurds

Benefits

• Primary aggregate in hempcrete mixes, combining low weight with high carbon storage
• Naturally insulating due to the hollow structure of hemp stalks
• Renewable and biodegradable, with a negative carbon footprint when used in construction
• Compatible with lime binders for hempcrete, plaster, and loose-fill applications

Application

Hemp hurds—the woody, carbon-rich inner core of the hemp stalk—are the primary ingredient in hempcrete. When mixed with a lime-based binder and water, these hurds transform into a high-performance, bio-composite building material that doesn't just insulate; it breathes.

Hempcrete’s unique thermal mass and acoustic properties make it an ideal solution for:

• Exterior Walls: Creates a monolithic, airtight thermal envelope that regulates indoor temperatures year-round.
• Ceilings & Attics: Provides lightweight, breathable insulation that prevents heat loss while managing moisture levels.
• Insulative Floors: Acts as a solid, slab-like insulation layer that provides a warm underfoot feel and eliminates drafts.
• Interior Partitions: Naturally dampens sound between rooms, creating a quiet, peaceful living environment.
• Heritage Retrofits: The "gold standard" for historic preservation; its high vapor permeability protects ancient timber frames from rot and decay.
