Hempcrete by EcoBouwSalland is a sustainable, bio-based building material designed for environmentally responsible construction. Made from hemp shiv, a lime-based binder, and water, it offers excellent thermal insulation, moisture regulation, and breathability while contributing to a lower carbon footprint.
Key Technical Specifications
- Density: ~275 kg/m³, ensuring a lightweight yet durable structure.
- Thermal Conductivity (λ): 0.06 W/m·K, providing high insulation performance.
- Compressive Strength: ~0.3 MPa, suitable as an insulating infill material in load-bearing frames.
- Flexural Strength: 0.3-0.4 N/mm², offering flexibility to adapt to structural movements.
- Fire Resistance: Rated at 1 hour (BS EN 1365-1:1999), enhancing building safety.
- Carbon Sequestration: Captures approximately 130 kg CO₂/m³, making it a carbon-negative material.
Material Composition
- Hemp Shiv: The woody core of the hemp plant, sourced sustainably.
- Lime-Based Binder: Provides durability, fire resistance, and natural pest prevention.
- Water: Ensures proper bonding and curing of the material.
Performance & Benefits
- Energy Efficiency: Reduces heating and cooling demands through superior insulation.
- Breathability & Moisture Regulation: Prevents mold and condensation by allowing walls to regulate humidity.
- Eco-Friendly & Carbon-Negative: Absorbs more CO₂ than it emits, contributing to sustainable construction.
