Queens Award winners in 2004, Second Nature UK Ltd is at the forefront of developing natural and sustainable insulation. Our collaborative research is aimed at developing products and markets from non-food crops such as wool and other materials that would otherwise go to waste.

Our Thermafleece range is the only natural fibre insulation in the UK to hold a BBA approval for use in loft, sarking and timber frame applications. When you specify Thermafleece, you can be confident that you are using the ‘best in class’ and ensure that the insulation used maintains its performance throughout the life of the construction.
