Black Mountain insulation is a general purpose natural sheep’s wool insulation product designed for use in loft, rafter, internal wall and inter-floor applications. Black Mountain is specified to match and surpass the Part L Building Standards with reference to Thermal, Fire, Mould Resistance and Structural performance. Black Mountain uses 100% virgin wool which is sourced from UK and Ireland, combined with up to 15% adhesive to bond the fibres together to maintain its thickness over the life of the product. The manufacture of Black Mountain insulation requires 90% less energy to manufacture than mineral wool insulation. In use, the durability and moisture control properties of wool allow for a higher level of performance and longevity – retaining its insulating properties for the life of the building. Black Mountain Wool is treated with boron salts so as to heighten its vermin and insect resistance for life of the product.
