2. To be effective, the surface aiding the blow in insulating material needs to be air-sealed.

Blow inside insulation can be not the excellent atmosphere barrier. In other key phrases, air flow passes right via that. When air can be permitted to pass through efficiency that looses it can insulation capacity.
