Insulation, Radiant and Vapor Barriers - Specific question about blowing Celluouse into a wall

Hello All,

I was looking at this video from This Old House and frankly, it seems too easy..

How to Retrofit Cellulose Insulation | Video | Insulation | This Old House (http://www.thisoldhouse.com/toh/video/0,,20047052,00.html)

For anyone who has done this can you please comment on this? The way it is done in the video the tube is stuck in the wall "straight on" i.e. not angled up or down.

I was always under the impression that you had to direct the tube up or down from where you insert it in the wall. This doesn't seem to be the case in the video. Is this really how it works? The celluose will spread out properly on its own?

Thanks for your insights, if this turns out to be true then it will make things easier for me.

Nope, that is the correct way. I am not a pro but I have used this machine 2 times on my house and garage. That is exactly how I did it, but instead of the shingle type siding I have wood lap, so I took off a strip of wood siding, drilled the holes in one weekend, then put the siding back up, then the next weekend we blew it in. My reducer, well it wasn't that nice. I had to buy one b/c the one that lowes was suppose to provide was already rented out.
I drilled my holes at 1 3/8". I went through 3 Irwin bits, they did great and held up great. I did use a coat hanger once and a while, but for the most part I could tell where the studs where b/c of the nails going through the planks behind the siding.
The angle of the hose was one of my questions when I first started doing research, but it doesn't matter. It blows in just fine and fills up evenly. All though this stuff will get hung up on elec. wiring and stuff like that. When I redid my bathroom, I tore the lath n plaster off and the one section was only partially full b/c of a wire.

Several years after I had blown my walls I did some major changes in the bedroom and had to remove some drywall from the floor to the ceiling. Every stud bay was uniformly packed with the cellulose and I had done nothing but drill the hole (about inch diameter) and inserted the cone and filled until the insulation stopped moving through the hose and it "blew back" slightly at the meeting of the cone and the hole.

So yes, it really is that simple.
