Hemp Slap Eco-construction

Premium-grade, raw hemp inner core (hurds) specially processed for on-site hempcrete and plaster applications. Raw, Untreated Core: Clean, locally sourced hemp hurds—no added chemicals or coatings—preserving natural breathability and insulating properties. Optimized for Blocks: Fiber length and bulk density calibrated for pumpable, form-stable hempcrete mixes; achieves consistent compaction and bonding when cast into block molds. Fine-Grade for Plaster: Screened to a finer consistency for seamless lime–hemp renders that buffer moisture swings and deliver a breathable, mould-resistant wall finish. Mix Ratio Guidance: Use a 1:3 volume ratio of lime to hemp hurds to create an effective scratch coat (≈225 ft³ total mix for 2,696 ft² of wall surface), with a 10 % waste allowance (≈200 ft³ of hurds)

Precision-cut, pre-cast hempcrete units engineered for fast, carbon-negative wall construction. Standard Dimensions: 1 ft (length) × 6 in (height) × 6 in (depth), yielding 0.25 ft³ per block Thermal & Carbon Performance: Delivers an R-value ≈9 per course and sequesters up to 110 kg CO₂ per m³ of hempcrete. Installation Efficiency: Corner-exclusion design maintains full stone thickness at junctions, while uniform block size simplifies layout and reduces cutting waste.

High-loft, loose-fill hemp fiber insulation for roof and wall cavities—perfect for thermal, acoustic and moisture control. Under-Slate & Ceiling Insulation: Fills gaps (e.g., 5 in under slates) to form a continuous thermal barrier. Thermal Barrier: Locks in warmth and buffers heat loss, eliminating drafts and reducing energy use. Moisture Management: Naturally hygroscopic, it prevents condensation and mold in enclosed cavities. Fire Safety: In combination with under-slate plaster and plywood, achieves 1-hour fire resistance at eaves.

High-density panels and beams manufactured from compressed hemp fibers and bio-resin—designed to replace conventional plywood and MDF in both structural and finish carpentry. Sustainable Source: Made from upcycled hemp hurds and long-fiber waste, our Hemp Slap Wood panels reduce deforestation and sequester carbon throughout their life cycle. Structural Strength: Available in standard board sizes (4′×8′ sheets at ¾″, 1″ and 1½″ thickness), plus custom-engineered beams up to 6″×6″—with bending strength and screw-hold comparable to pine. Moisture & Pest Resistant: Naturally resistant to rot, mold and insect attack; ideal for kitchens, bathrooms and exterior soffits when sealed with eco-friendly finishes. Acoustic & Thermal Benefits: The hemp core dampens sound transmission by up to 20 dB and adds R-value (≈R-0.5/inch), improving indoor comfort and energy efficiency. Easy Workability: Cuts, sands and routs like wood—compatible with standard woodworking tools and fasteners.
