Wool. Smart Technical Fibre
Manages cold and hot conditions
Wool is a superb thermal insulator. That is what it evolved to do. It is comparable or better than either stone or glass "wool"
But it also manages warm conditions far better. It has a high Specific Heat Capacity and high thermal mass helping to keep your property cool in summer
Helps manage damp, humidity and moisture
The exterior of a wool fibre is hydrophobic so it doesn't feel wet. The interior is hygroscopic meaning it can absorb moisture vapour in times of high humidity and release it in the form of heat in times of low humidity. Hygroscopic materials are very important in managing the health of the building and the health of occupants. Managing humidity within a building also has an effect on energy demand and therefore cost
Good for old and new buildings
Sheep wool insulation is fully breathable and can manage the conditions of both old and new buildings
Healthy people
Sheep wool absorbs and locks away Volatile Organic Compounds such as formaldehyde which are found in many common household goods. It therefore can contribute to a healthy indoor environment
