What is loft insulation?
We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.
- Waste packaging removed
- Area under the cold water tank left clear so it cannot freeze
- Cables lifted clear of the insulation where possible
