Anyone here ever blow their own cellulose insulation in their attic? I did the rolls of batting in my old house and it made a noticeable difference but there wasnt barely any insulation up there. I was thinking of adding like 6-12 in in my current house to further increase my insulation. I think I have about 8-12in of blown in glass fibre currently. But during my home inspection, when we bought the house, the dude told me it needed more. In the summer its hard to get my house to cool down with the AC running nearly non stop during the 90F days. Its a 2000sq foot ranch.
I heard the cellulose was better all around insulator and I would like to do this myself maybe renting the machine soon before it gets too hot to be up there.
Yes, we did this 2 years ago, rented the machine from Home Depot and blew in about 6 more inches of insulation into the attic.
Its a 2 person job, 1 person has to feed the insulation into the machine, while the other person blows the insulation in. The feeding process can be a damn mess, so what we did was make sure we rented like 30 feet of blowing hose, so we could keep the machine itself outside in the driveway, and just fed the hose through a bedroom window and into the hallway where the attic door is.
now, this is all well and good and everything was running smoothly and easily until...
I'm up in the attic blowing the insulation while my wife is in the driveway feeding packages of insulation into the machine. The insulation pauses every once in a while during the re-loading process, the machine just keeps blowing constantly, its turned on and off at the machine, theres no controls on the hose, you just hold it and shit shoots out. At one point the insulation stops blowing, I figure she's reloading. But a few more minutes go by, and a few more minutes, so I stick my head down out of the attic and yell WTF is going on?. She can't hear me because the machine is loud as all hell, and she's outside the house to boot. So I go down the ladder, go outside and see her standing there, feeding insulation in like normal. I ask her why she stopped for so long, she says she didnt. Hrmmmm. I go back in the house and into the bedroom where the hose is coming through the window...INSULATION EVERYWHERE. To get the hose long enough to work for our setup, we had to rent 2 hoses and duct tape them together. Well, that had split apart and ALL the insulation for the previous 10 minutes was just blowing straight into the bedroom. The bedroom was filled wall to wall with about a foot of insulation. I stick my head out the window and yell at my wife to turn the goddamned machine off. We spent the next 3-4 hours shoveling insulation from the bedroom floor into trash bags, so it could be dumped back into the blowing machine, and we spent the next 6 months vacuuming up insulation in that room. It seemed to never end, just when we thought it was clean we'd fine more. It was a goddamned nightmare.
So have fun
