Sheep Wool Loft Insulation Installation in Cawsand Ross wanted an eco-friendly insulation solution for his pre-1920 home in Cawsand. After discussing options, he chose sheep’s wool insulation. We began by removing all existing loft insulation and vacuuming the loft floor to eliminate fibres and debris. We installed 240mm of sheep’s wool insulation, including insulating the exposed gable, and added eaves vent trays for proper ventilation. The project was completed with the installation of a store floor and boarding for added functionality.
