Havelock Wool resists mold and mildew
Mold and Mildew are not part of a Healthy Home
A damp and moldy environment is detrimental to your health so it’s crucial that your home insulation resists mold and mildew to avoid an unhealthy living environment. Havelock Wool is a protein-based keratin thus naturally mold resistant.
Moreover, the outside of a wool fiber consists of overlapping cuticle cells that naturally repel water (hydrophobic). So water is not easily available on the surface for mold to grow.
Wool actively manages Relative Humidity
In a brilliant twist of evolution, the interior of the wool fiber is actually hygroscopic meaning it has a high moisture buffering capacity. Water vapor is able to pass into the interior of the fiber. This is how wool can absorb up to 33% of its own weight in water and still feel dry to the touch. So wool traps moisture inside the fiber (where mold spores cannot get to it) which moderates the relative humidity of your wall cavity and your living space.
