What is blown loft insulation?
The machine stays outside or on the landing and the hose runs up to the loft. We hold a board or tray at the eaves so the loose fill cannot block the ventilation path. More about blown loft insulation.

Is it messy?

Mineral wool loose fill settles a little, which is allowed for in the depth we install. The depth markers let you check it later.
