A truly sustainable insulation produced using British Wool and manufactured in the UK.
Great for loft insulation, wall insulation and floor insulation. It has high acoustic insulation properties so it is also great for partition walls, campervans and as part of a soundproofing system.
Sheep wool insulation has a very low embodied energy, and acts as a moisture buffer by absorbing and releasing excess moisture (can absorb up to 30% of weight for weight in 100% relative humidity conditions). Like all Thermafleece wool products, it is long-lasting, safe to handle, itch free * and can contribute to a healthier indoor environment by acting as a moisture buffer and absorbing indoor pollutants such as formaldehyde in the building fabric.
This product may smell sheepy, which can become more apparent when in close proximity to it. If you are sensitive to this please consider another product. Given time to air any smell will dissipate.
