Blowing loose fill cellulose insulation into your walls is a pretty neat process (even though the insulation contractors were really crappy and we had to make them come back twice to fix all the many spots they missed).
They cut lotsa holes all over your walls, then take tiny little fuzzy bits of recycled paper (treated to make ’em fireproof and unappealing to critters), load ’em into this big blower fluffer machine, and then shoot the stuff through incredibly long hoses run up from the street into all the holes until your walls are filled up! Whew. So much dust everywhere… Hard to believe none of the workers ever wears a dust mask.
