Is blown insulation better than rolls?
It performs about the same for the same depth. It is the faster and neater option in lofts that are awkward to work in, and rolls are better where you want boarding later.
Is it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
