Bringing together structural design and thermal performance!
Section 1 : Introduction to Hempcrete
Hempcrete has excellent insulating properties, providing thermal regulation by allowing the building to breathe and reduce moisture build-up. The thermal conductivity of hempcrete is typically in the range of 0.06 to 0.07 W/mK, which is about half the thermal conductivity of concrete.
One of the primary advantages of hempcrete is its sustainability. Hemp sequesters carbon dioxide from the atmosphere during its growth, making it a carbon-negative material.
The 25 cm block is perfect as interior or exterior insulation, it is highly efficient and can be used as a wall block in any construction system. Its thermal resistance of more than 35 m²K/W guarantees high energy efficiency, for optimum comfort in multitude of climates and in any season of the year. It regulates humidity and insulates acoustically.
