Sheep Wool Insulation products have unrivalled environmental credentials, making it them the "greenest" choice of any insulation product on the market. Sheep's wool is a naturally occurring fibre, so it is a renewable and sustainable source of raw material. Wool has zero global warming potential and is carbon neutral, so choosing Premium means your insulation will have no environmental impact. Sheep Wool Insulation also requires only a fraction of the energy to produce in comparison to other insulation materials. At the end of its useful life, Premium can be reused as insulation, recycled into other wool products or buried where it will eventually biodegrade.
