Your instructor

“Chris had been a builder and has built his own beautiful Passivhaus, so, unlike most importers of building materials, he completely understands what goes into every aspect of building a house, he really knows his materials and how they fit into an entire house build.”

This course has been expertly curated by Chris Brookman, founder of Back to Earth. Chris has over 21 years of experience working in sustainable construction.

During that time he’s worked on numerous building projects, ranging from major residential developments to one off, self-build projects. You can find out more about his work here. Chris has developed this course to allow others to gain a deeper understanding of wood fibre insulation and how to use the material effectively.

If you are an architect, builder or even self-builder and are considering using wood fibre insulation, this course is designed for you.
