While Al was in the attic with the hose blowing in the insulation, I was breaking up the cellulose insulation and filling up the blower. It's messy work, hard on the back but I wouldn't classify it as hard work.
When we built our house sometime ago we used panel insulation. It was a bit overwhelming because bits of fiberglass would cling to my clothing and would find their way to any exposed skin I had forgotten to cover up. But this process was a whole lot easier.
Setting the blower up was easy but you have to do it correctly for it to work efficiently. The bigger gauge(wire) and the shorter cord seemed to work better. The blower will shut itself off from time to time if something isn't connected correctly. Or it may not start at all, depending on what is wrong with the connection.
The blower works better when you break up the cellulose into small pieces, the bigger chunks take the blower longer to process. This fiber material is not the old fiberglass material, this is an 85% recycled material made from newspapers that includes a fire retardant. However, you still need to wear protective clothing - gloves and a breathing mask for sure. You do not want to breath in this stuff. I don't think I would do this if I had asthma or any respiratory issue. As with any project you endeavor always read all the instructions first.
So, that project is done. Onto the next one.
