Prefab hemp-lime wall systems

Cancret produces patented prefabricated hemp‑lime wall elements that replace conventional insulation and façade systems in modern timber construction. These walls are CO₂‑negative, cost‑efficient, and ready for industrial scale, making climate‑positive building both practical and profitable.

What the product is

A lightweight, prefabricated wall element made from hemp, lime and a timber frame.
It arrives on the construction site ready to install — fast, clean, and highly efficient.

What it does

• Stores 105 kg CO₂ per m³, turning every building into a long‑term carbon sink

• Provides excellent insulation without additional materials

• Regulates humidity naturally and improves indoor air quality

• Is fire‑resistant, sound‑absorbing and fully recyclable

• Reduces construction time and on‑site complexity

Why it matters

Our patented production method cuts costs from CHF 800 to CHF 200 per m², making hempcrete for the first time competitive with conventional materials.
This unlocks a massive global market for sustainable construction — and positions Cancret as a scalable technology provider in a sector growing 11–14% annually.
