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.

Through our unique understanding of building materials and the construction process we provide the most energy efficient materials available to create comfortable and healthy indoor spaces.

Many of our products are made from recyclable and recycled materials, ensuring the minimum impact on the environment and allowing you to create a true eco home.

If you'd like to get in touch to discuss your project, we'd love to hear from you. We're always happy to talk things through and share our ideas on how to make your sustainable building project a success.

How do I internally insulate an old building?

July 20, 2016

Can you suggest any materials for internal insulation of an old building? For internal insulation you could use our UdiIN or UdiINRECO systems which are both wood fibre insulation board based system that are fixed to the interior of the walls to insulate. They are extremely good at managing moisture and help dry buildings out. In addition to the internal insulation you would need to look at the exterior of the walls as it becomes important to ensure that driving rain does not accumulate in the walls. We would normally recommend that the exterior is either rendered or has an impregnating, water repellent cream applied to it to ensure weather tightness. For roofs I would suggest the UdiIN wood fibre insulation...

Introducing a wood fibre insulation board specifically designed for uneven surfaces

July 20, 2016

How does UdiRECO compare to Polystyrene or PIR boards? The 80mm UdiRECO board has an overall conductivity of 0.044 W/m2K so would be equivalent to 60mm of grey EPS or around 40mm of PIR. However, neither of the other two are able to manage moisture and I would never recommend that they be used internally. They are very likely to allow the accumulation of moisture within the wall construction which in turn is likely to allow the decay of the joist ends or lintels in your wall. Wood fibre manages this extremely well and will, with the right wall preparation, prevent this accumulation occurring. How does UdiRECO compare to insulating plaster? Compared to Baumit DP85 insulating plaster, the UdiRECO system...
