Anyone know if I can blow in cellulose insulation into my walls myself.
I'd really like to get that insulation that sticks to the walls, and
then you cut it flush with the wood. Can this be done yourself.

Thanks

The stuff you blow into the walls has more moisture and requires a special
machine to blow in. If you can get one of those, then you can easily do it
but I don't know of anyone who rents them and they are prohibitively
expensive. In the alternative, you can use some barrier (one manufacturer I
know of makes a mesh netting) which you staple to the studs in order to hold
the cellulose in place. It's a hairbrained idea though and I wouldn't go
this route becuase, regardless of whatever anyone tells you, the standard
blowers just don't have enough power to compact the cellulose to specs.

Exactly, Crhras,

even though you can rent the blower equipment (I am not from US, but as
far as I know it costs some 50+ USD daily and some 50 - 100 USD deposit
upfront), usually you need much more than just a good blower, it is the
matter of technique... and the vertical walls are the most difficult
job for the cellulose insulation.

Rather just let it on profi, JayMay,

When I purchased this house (built in the 40's) the first thing I did
was insulate the enire thing. I blew cellulose in the walls and in the
attic space with a rental unit from Lowes for FREE. I did this first
because P.G.& E. was offering a rebate that virtually paid for it.
Since then I have opend up several walls for various reasons and I was
very impressed with how completely it was filled and compacted. This
ofcourse was done with the drywall already on.

hmm..

Really hate paying for something that I can do, and it looks pretty fun
to boot. I gutted our house 4 years ago and had a company re-insulate
the walls by putting up cheese cloth and then blowing the cellulose
into it.

Problem is, if you DIY your drywall, it will take you awhile to put it
all up I hung 170 sheets in a little over a month. Some of the drywall
is really hard to get on because the cellulose starts buldging out of
the walls. Some cases I had to hold the drywall up, push the cellulose
back in, and then attempt to screw the drywall to the stud without
having the screws pop through. REAL PITA.

Also, since the ceiling drywall wasn't up, they couldn't blow cellulose
up there. Instead they put netting up, and blew in really light
fiberglass. I don't think that stuff insulates that well at all.
