Sheep Wool Loft Insulation Installation in Aberdeen Mrs. Bell sought a complete insulation renovation, transitioning from old fibreglass to Sheepswool insulation.Our process began with the removal and proper disposal of the old insulation. We then meticulously cleaned the loft, sweeping and vacuuming thoroughly. Next, we installed 240mm of Sheepswool insulation and added BBA Approved raised boarding to ensure a high-quality finish.
