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.

Questions about blown loft insulation in Portstewart

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