The ability of wool insulation to absorb and release moisture from the surrounding air, while maintaining its thermal performance, is a unique advantage. When wool insulation fibers absorb moisture, they generate tiny amounts of heat. This warmth acts to prevent condensation in construction cavities and creates a natural buffering effect, stabilizing heat changes that occur with relative humidity. This reduces the need for adjusting heating or cooling levels as wool insulation will keep a building cooler during the day and warmer during the night.
Being made from a naturally produced fiber, Sheep Wool Insulation requires less than 15% of the energy required to produce than fiberglass insulation. Wool is a sustainable and renewable resource that has zero ozone depletion potential and at the end of it’s useful life can be remanufactured or biodegraded. It can also absorb and break down indoor air pollutants, such as formaldehyde, nitrogen dioxide and sulphur dioxide.
Because the wool is natural, it is safe to handle and does not require special equipment or safety clothing. You can fit it anywhere – from external or internal walls, under timber or concrete floors to the attic/loft or between the rafters. If you want to make existing attic/loft insulation more effective, you can roll out Sheep Wool Insulation over the existing insulation rather than having to remove it. This can also be safer than removing hazardous material.
