We were recently commissioned to complete a loft insulation project where, at the client’s request, we installed sheep’s wool insulation instead of the Knauf glass wool we typically use.

While this natural material comes at a higher cost, it is steadily gaining popularity due to its environmental and performance benefits. Sheep’s wool is a sustainable, renewable resource that requires minimal processing, making it an eco-friendly alternative.

It also offers excellent thermal performance, helping to regulate temperature effectively throughout the year, and has the added advantage of being breathable, which can reduce the risk of condensation and damp issues in the loft space.

Additionally, it is safer and more pleasant to handle during installation, as it does not irritate the skin or release harmful fibres. This project highlights the growing demand for greener building solutions, even where they come at a premium.
