Hemp Block Insulation – Less Is Now Officially More!

At The Hemp Block Company, we’re redefining what’s possible in sustainable construction across the UK. The latest development marks a major leap forward in hemp block innovation, offering exceptional insulation performance with even less material.

Improved Thermal Efficiency, Independently Verified

Independent testing, confirmed by our partners at Senini, has shown that our hemp blocks now achieve an impressive thermal conductivity of 0.044 W/m·K.

This enhanced performance means that builders, architects, and homeowners can now enjoy better insulation from a thinner wall — reducing both material use and overall construction costs. In other words, less really is more.

Why ‘Less’ Means More for Your Building Project

  • Lower build costs & reduced embodied carbon through the use of less raw material
  • Thinner wall construction, freeing up valuable internal floor space
  • Superior insulation performance, reducing energy use and improving comfort all year round

This breakthrough reinforces The Hemp Block Company’s position as a UK leader in eco-friendly, high-performance hempcrete block supply — allowing low-impact building solutions that don’t compromise on quality or sustainability.
