Back to Earth provides essential knowledge and materials to those seeking to improve building performance.


The solutions we offer at Back to Earth are practical, robust and above all, simple.

We offer design and installation guidance on all of our products so if these materials and systems are new to you or you need any advice, just call or email us with any questions and we’ll do our best to help.

We take a ‘Fabric First’ approach to construction which focusses on the materials used to build or renovate your home before deciding on the systems that will heat, ventilate and cool it.

Our focus is on roof, wall and floor insulation and how they can help keep you warm in winter, cool in summer and improve resilience.

This way we can help you create highly efficient, low energy or Passivhaus homes which stay comfortable in a warming world.

The materials and systems you see here are an investment into the fabric of your home, one that helps reduce your reliance on heating, cooling and excessive ventilation.



The products are selected from companies who demonstrate high levels of both technical and practical understanding.

This ensures we can give you the help you need to use them and that you’ll be happy with the final results.

Understanding A Building's Thermal Performance Using U-values

November 16, 2016

The U-value of a building element, such as a wall, roof or floor, is a measure of the thermal transmittance of that element. The lower the U-value, the slower the flow of heat is through that element once it has reached a steady state (meaning the flow of heat through...
