Slimmest Blown Cellulose Insulation Cavity?
Another question here. Hoping someone from the insulation community can give me an answer.
What is the slimmest insulation cavity that can be blown? Is it possible to blow 1.5″ to 1.75″ thick cavities? It seems like you could…you would just have to have a hose that was small enough right?
The reason for the question: if I wanted to build a strapped wall, install an air barrier between the strapping and the studs, and then fill that 1.5-1.75″ cavity with more insulation could I do it? I realize I could probably use fiberglass batts for this but let’s just say I don’t want to.
