In the form of vapor, condensation or water- moisture will inevitably make its way into your walls. You need an insulation that actively manages that moisture, helping keep your house dry and free of mold and mildew. Unlike any other insulation, wool is naturally able to absorb moisture while still retaining it’s high insulative properties. When the ambient air dries (>65%) wool will release the moisture into the air. The result is a long lasting, non-slumping, high performance insulation that keeps your walls dry, temperatures more constant and energy bills low.
