Carbon - Storing Walls Meet Hempcrete

Hempcrete = carbon‑storing, low‑impact, great insulation. Here’s why more teams are testing it for walls & retrofits.

 

Carbon accounting: Biogenic uptake during hemp growth + binder carbonation can yield net‑negative GWP at the assembly level in many studies.

Envelope performance: Low density and high porosity improve phase shift and damp temperature swings—boosting comfort and reducing cooling loads in hot‑humid climates.

Design notes: Use appropriately graded hurd; consider pre‑cast blocks/panels to reduce on‑site variability; ensure vapor‑open interior finishes to preserve drying potential.

Risk management: Detail window/door interfaces and base flashing to avoid capillary uptake; specify curing times and protection from early rain.
