i wonder does it work as good as the stuff we use now?

Sounds cool, but will Adrian come install it for me...please

KACIEJPC, it's actually better, across the board. Take a look at these facts I found online comparing cellulose insulation and fiberglass insulation:

Studies comparing blown-in cellulose insulation versus fiberglass insulation show that cellulose insulation was 38% tighter and required 26% less energy. A Princeton University study shows that a group of homes with blown-in cellulose insulation in the walls had an average of 24.5% reduction of air infiltration compared to fiberglass insulation, with only the walls insulated. A similar study, the Leominster MA Housing Project for the Elderly found that a building with blown-in cellulose insulation compared to a building with R-13 fiberglass batt insulation in the walls and R-38 fiberglass batt insulation in the ceiling had 40% lower leakage.

HeHe, go adrian! rock on w/ your insulation.

i recently retrofitted my place with cellulose, blown into the walls and roof cavity. i wanted airkrete (a cementitious insulation) or the denim adrian used, but airkrete was far too expensive and the denim isn't good for retrofitting closed cavities. i'm happy with the cellulose. in addition to being a good thermal insulator, it's also a decent acoustic insulator.
